Elliptical Machine vs. Treadmill: Which Cardio Machine Will Be Best for Your Workouts?
"CARDIO MACHINE" HAS become a catch-all term to describe exercise bikes, treadmills, rowers, and ellipticals. Categorizing an entire section of your commercial gym can be practical, sure—but the unique benefits of each type of apparatus get lost in that label. Not all cardio machines are created equal, and the one that works best for you will depend on several factors, like your goals, your weight, and your injury history, and more.
Two of the most popular options are the treadmill and elliptical. You'll find them in virtually every gym, from mom-and-pop shops to big-box chains. Both allow you to get moving and raise your heart rate—but that's where the similarities stop.
To help you figure out whether you're #TeamTread or #Elliptigain, we spoke to Chris Parnell, an NYC-based personal trainer and Men's Physique competitor in the World Natural Bodybuilding Federation.
The Differences Between Elliptical Machines and Treadmills
Let's start with the commonalities these two cardio titans share. Both have controls that allow you to alter the speed, incline, and resistance of your workout; they enable you to jack up your heart rate, and they let you move on a fixed path in the sagittal plane (movement when your arms and legs move forward and backward).
Other than that, the look of these cardio machines and how they feel when you use them are completely different. Here's how each machine moves, feels, and fits into a workout.
The Treadmill
The treadmill is a long platform with a motorized belt tread that allows you to run in place. Runners of all levels use treadmills for training, both as an all-weather option and for specific workouts designed to maintain a consistent pace or incline level, which can be a useful approach to improving performance and fitness.
Many folks gravitate to treadmills because they let you walk and run indoors, they're great for performing intervals since you can easily hop off them, and if you crank up the incline, they provide a killer hamstring and glute workout.
'The treadmill is the most practical machine to progress a client with,' says Parnell. 'Most clients come to me to improve body composition, so I'll start them with walking, progress to a brisk walk, and eventually incline walking. The goal is to keep the heart rate between 60 percent and 80 percent of their max. There are plenty of calculators online to help estimate that.'

The Elliptical Machine
On the other hand, elliptical machines are clunkier-looking rigs with two upper-body handles and two foot pedals that rotate back and forth on a fixed track in an elliptical motion. They're meant to mimic the movement patterns of running and walking, but don't require striking a surface with your foot.
'This is a low-impact aerobic machine, which is advantageous for promoting joint protection,' says Parnell.

Benefits of the Treadmill
Allows for Running Training
Ellipticals may mimic the motion of running, but only the treadmill lets you actually walk, jog, or run. 'The specificity of how humans move is the treadmill's biggest strength,' says Parnell.
Running in place in a controlled environment might have some purists foaming at the mouth—but no machine better replicates actual running mechanics than the treadmill. And there are some advantages—treadmills let you run uninterrupted by traffic lights, uneven sidewalks, or unpredictable weather.
Supports Sprinting and Intervals
Treadmills are ideal for structured interval training. Many models include built-in timers or interval modes that let you program speed shifts every 30 seconds or minute. Even without those features, transitioning between sprints and rest is seamless—you can straddle the belt during recovery and jump back on when it's go time.
Allows for More Challenging Workouts
Many treadmill models allow you to manipulate the incline to challenge your posterior chain. Crank it up, and your glutes and hamstrings will fire as you drive up the slope.
One of the most popular examples is the viral 12-3-30 workout: set the incline to 12%, speed to 3 mph, and walk for 30 minutes. It sounds simple…until you try it. The climb creates more muscular demand than a flat jog.
Benefits of the Elliptical
Easier on Your Joints
Ellipticals have large foot-shaped platforms you stand on, as you glide back and forth like you're in La La Land. Because your feet never leave the pedals, there's no pounding or ground reaction force with each stride.
That means you lose out on the bone-loading benefits of treadmill walking but gain something arguably more important for many lifters: Less joint impact.
If you have a preexisting injury, always check with a medical professional before using a cardio machine. That said, the elliptical is generally considered a safer option for people with lower-body joint issues than high-impact options like running.

Friendlier for Bigger Builds
If you're carrying more weight—whether muscle, body fat, or both—the elliptical may be the more comfortable choice for cardio. Since it's a zero-impact machine, you're not putting stress on your joints with every stride like on a treadmill.
There's also a coordination factor. Treadmills require more balance and rhythm to walk or run fluidly on a moving belt. If you're on the heavier side, that can feel awkward. The elliptical, on the other hand, locks you into a fixed path, reducing the chance of tripping or misstepping. It keeps your movement smooth, controlled, and safe.
Better for Long, Slow, Steady State Workouts
Some guys want to hit the gym and just move for extended periods, with a TV or a book for company. If you like to read or stream while you do cardio (no judgment here), the elliptical is your best bet. Because it requires less balance and coordination than a treadmill, there's a much lower risk of wiping out mid-episode.
And if you're logging 30 minutes plus per session, pairing your cardio with a show or book can turn a slog into something you actually look forward to. Think of it as a smart way to double-dip on your 'me time.'
Which Machine Burns More Calories?
Calorie burn will be largely variable depending on individual factors, so shouldn't choose your cardio machine based solely on numbers. If you train hard, stay consistent, and manage your nutrition, both machines can help you torch fat and boost endurance. The quick answer, though: Running on a treadmill will likely burn more calories than a hard elliptical session.
According to the Compendium of Physical Activities, running on a curved treadmill at 7 MPH burns 11 metabolic equivalents, or METs. METs are a unit of measurement of your working metabolic rate versus your resting metabolic rate. They scale, so the more intense the activity you're doing, the more your METs multiply. Comparatively, using an elliptical at a 'vigorous' effort burns 9 METs.
Once you know your METs, you can determine your total caloric burn using this formula: METS x 3.5 x BW(KG) / 200 = kcal per minute. Say you weigh 180 pounds, using this calculation, you'd burn 15.5 calories per minute running on a treadmill or 12.7 calories per minute during a brutal elliptical workout. You can also use this calculator to get an idea of how many calories you burn during various types of exercise.
Which Cardio Machine Should You Use?
There isn't a wrong answer to this question. Both the elliptical and the treadmill are solid ways to add cardio training to your routine. Some people might have better experiences with one over the other, though, depending on their individual needs. Here are some factors you can consider that will help you choose the best cardio machine for your training days:
If You're a Runner: Treadmill. Since the treadmill lets you run freely, this is the best option for folks who are focused on run training.
If You Have Achy Joints: Elliptical. Since the elliptical is a zero-impact machine, you won't risk aggravating your knees, hips, or ankles.
If You Prefer Long Steady State Cardio Sessions: Elliptical. Again, it's a no-impact machine that requires less coordination, making it a safer pick for lengthy workouts.
If You Want to Do Sprints or Intervals: Treadmill. You have better control over your sprinting mechanics (hip extension and knee flexion) and can easily hop on and off the belt.

Mushroom boom hits your sips and snacks
Mushrooms are sprouting up all over the place: in coffee, soda, chocolate and meat blends. Why it matters: Centuries after they were considered medicinal, mushrooms are today's go-to "functional" food — with a brain-boosting, sustainable aura. State of play: "Mushrooms have such a health halo," says Chicago-based registered dietitian Janet Helm. Plus, they're versatile. "Particularly with Gen Z, if you put it in a beverage, they love it." That's largely because of sustainability and brain-boosting reasons. And mushrooms are a key ingredient for the emerging category of part-veggie, part-meat foods. The big picture: "It's not just your white buttons anymore," Helm says. Specialty mushroom varieties have doubled in sales in the past decade, according to Mushroom Council president Amy Wood. Between the lines: We're not talking about "magic" mushrooms. "Functional" mushrooms include lion's mane, chaga, reishi and cordyceps (something "The Last of Us" fans might be familiar with). Zoom in: Mushrooms are a good source of the antioxidant ergothioneine and B vitamins, which could all support the brain, Helm says, referencing a growing body of research on mushrooms' cognitive health benefits. By the numbers: Sales of food and beverages with functional mushrooms are up over 450% in the U.S. since 2021, according to NielsenIQ. Mushroom coffee is one driver of that growth. Dollar sales are up about 55%, and with volume sales up 74% so far this year (through July 13) compared to the same time last year, that's a clear sign it's gaining momentum, according to Circana industry adviser Darren Seifer. Reality check: Mushroom coffee is still a "very, very tiny" slice of the coffee market, making up less than 1% of sales, he says. Catch up quick: After mushroom coffee company Four Sigmatic kicked off the trend about a decade ago, starting the day with a mug of mushrooms caught on. How it works: To make the "coffee," mushrooms are blended with coffee beans or tea, or they're often used as part of a coffee alternative powder that might contain added caffeine. The drinks don't taste mushroomy, per se, but can err on the "earthy" side. Often, though, they're made with sweetener and prepared with milk, so the flavor is more "chai" or "mocha latte" than "topsoil." 💭 Carly's thought bubble: Consuming mushrooms is a vibe.

Here's When You Can Expect To See Results From Your Workouts, According To Experts
"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links." If you've just started a workout routine for the first time—or maybe you're trying out a different style of training than you're used to—you might find yourself wondering, "How long is it actually going to take before I see results?!" Whether you're hoping to see changes in the mirror, on the treadmill numbers, or in your energy levels, this is one of the most common questions people have when it comes to exercise. The reality is, seeing changes to your physical and mental health looks different for everyone and doesn't happen overnight, but there are clear signs you can expect in both the short and long term that show what you're doing is working. Exactly how long it takes to see results from working out varies widely, says Danyele Wilson, CPT, trainer for the app EvolveYou. Those noticeable physical changes from exercise (be it muscle growth, fat loss, or a lower resting heart rate) depends on the person and their baseline level of fitness. "My [clients] generally see initial changes within four to six weeks, and actual results within eight to 12 weeks," Wilson says. And, no two people have identical goals or workout programs to reach them, meaning that the general timeline (eight to 12 weeks) to see results of any kind from working out is pretty malleable. Below, fitness experts delve into how long it takes to see results in aerobic capacity, weight loss, muscle definition, mental health, and more—and what it actually takes to get there. Meet the experts: Danyele Wilson, CPT, is a trainer for the app EvolveYou. Jason Machowsky, RD, CSCS, is a sports dietitian and clinical exercise physiologist. Brooke Taylor, CPT, is a personal trainer and owner of Taylored Fitness NY LTD. N'Namdi Nelson, CSCS, is an exercise physiologist at the NYU Langone Sports Performance Center. Chloe Carmichael, PhD, is a WH advisor and a New York–based clinical psychologist. How Long It Takes To See Improvements In Aerobic Capacity The verdict: Eight to 12 weeks Upping your cardiovascular endurance and shaving minutes off your racing time doesn't just result in a serious self-confidence boost—you're likely to gain a trove of other health benefits, too. In fact, marathon training can help to decrease stiffness in your arteries and combat high blood pressure, according to a 2020 study in the Journal of the American College of Cardiology. Of course, scoring a new PR and lowering your heart rate a few beats per minute (when your cardio endurance improves your resting heart rate usually goes down) are two very different goals—with varying timelines. If your aim is the latter—to generally boost your cardiovascular health—eight to 12 weeks is a fairly solid period to do so, says Brooke Taylor, a a New York City-based personal trainer and owner of Taylored Fitness NY LTD. 'This involves a minimum of 30 minutes of moderate-intensity cardiovascular exercise three times per week,' Taylor says, noting that several other factors—from sleep patterns to even your menstrual cycle—can play a role in your resting heart rate. If you're a beginner, you'd ideally want the exercise to get you to 30 to 40 percent of your heart rate reserve. To calculate your heart rate reserve, subtract your resting heart rate from your maximum heart rate. Maximum heart rate can be calculated by multiplying your age by 0.7, then subtract that from 207. (So for a 30-year-old, it's 207 minus (30 x 0.7), which gives 186.) Resting heart rate is how many times your heart beats per minute when you're just sitting around—not stressed, caffeinated, or moving. You can get this number at home by simply placing two fingers on your wrist or neck and counting the beats for 60 seconds. A supercharged style of aerobic exercise like interval training and high-intensity interval training (HIIT) can improve your resting heart rate, possibly even faster, Wilson also points out. 'An athlete can typically start to lower their heart rate within a couple of weeks of training,' she says. 'Evidence suggests that interval training is the superior method to do so.' Another 2020 study published in the Journal of Translational Medicine found that HIIT in particular can have a greater impact on reducing resting heart rate than both moderate-intensity interval training and moderate-intensity continuous training, like jogging. As for an improvement in your speed and endurance, Wilson and Machowsky explain that it depends on the individual, and it's largely based on your training history and current fitness level. For instance, endurance-wise, your aerobic capacity might feel better in four to six weeks, but it'll take longer for there to be objective improvements. 'If you are currently inactive, you can see improvements to your VO2 max capacity within four to six weeks,' Wilson says. 'Depending on the training program, a beginner can be half marathon-ready in roughly 12 to 20 weeks.' (VO2 max is basically the maximum amount of oxygen your body can consume and deliver to your organs and muscles, according to the American Council on Exercise. The higher your capacity, the longer, and stronger, you'll be able to engage in cardiovascular exercise.) How Long It Takes To Lose Weight (And Keep It Off) The verdict: Eight to 16 weeks First thing's first: The decision to lose weight is a highly personal one. And not everyone is at the same starting point when it comes to shedding pounds. If you have a history of being overweight (or a family member who does), have been diagnosed with a hormonal disorder, have a chronic health condition, are experiencing a mental health issue (like depression or anxiety), or are on certain medications, it might be more difficult for you to lose weight compared to someone who does not. Extraneous factors preventing weight loss aside, burning more calories than you consume—a.k.a. a 'calorie deficit'—still remains king for weight loss, notes Taylor. Basically, in order to lose one to two pounds per week, you need to create a 2,000 calorie deficit per week. If you're trying to measure weight loss through waist circumference or body fat percentages, generally wait eight to 12 weeks to notice a difference, or even upwards of 16 weeks, Machowsky says. (If you're following a specific weight loss program, it could take less time to see differences, he says.) As for when that weekly deficit will result in meaningful changes that you notice? That depends on a number of factors (10 pounds might look different on your average 5'2' woman as opposed to a 6'3' competitive athlete). One 2015 study from Social Psychological and Personality Science found that a 2.93 change in BMI (or body mass index) was what it took to make weight loss (in your face, at least) apparent. And while *technically* you could create that calorie deficit through exercise alone, think about it: Although it could take you minutes to consume 300 calories, burning that same amount could take upwards of an hour! That being said, if there's one exercise that can considerably boost a weight-loss effort, it's strength training. A review of studies in Metabolism found that the best way to boost your basal metabolic rate, or how many calories you're able to burn at rest, is to have more muscle mass. And the magic ingredient behind increased muscle mass? You guessed it: hitting up the weight room. WH-Approved Dumbbells To Level Up Your WorkoutsHand Weights $14.81 at Dumbbells $151.98 at Bars $55.00 at HIIT might also contribute to a longer-lasting calorie burn, according to a 2017 study from the European Journal of Applied Physiology. When compared to steady-state, moderate-intensity cardiovascular training, participants in the study who engaged in HIIT continued burning calories long after their training was over. (The study notes that, while there's a modest calorie burn after a moderate-intensity workout, it's not nearly as much as HIIT.) Of course, to reiterate (over and over), weight loss is a multifaceted, complicated journey. Taylor believes that the combo of an adequate calorie deficit, strength training, and cardio training is the most efficient and healthiest way to reach your goals. 'When a client is onboard [with those three changes] and is willing to adapt, big changes can happen within three to six months,' she says. 'Again, however, it depends on how well the client adheres to the program.' How Long It Takes To See Results From Lifting Weights The verdict: Six to eight weeks, or as soon as four weeks for beginners Unlike improving your cardiovascular health or losing weight, you might see increased muscle gains from a strength training program after a single session, experts say. That's due to a phenomenon called 'muscle pump,' which is just a casual term for the increased blood, oxygen, and lactic acid that's being moved to your muscles during a super-intense lifting session. (Granted, it's only a temporary movement of fluids, but hey, it's something!) Machowsky adds that strength gains can initially happen within four to six weeks if you're new to lifting because of neuromuscular adaptation—a.k.a., your body is becoming "more efficient using the existing muscle to move the weight," he says. It's less about an increase in muscle mass and more about the efficiency of the muscle, he adds. Consider that initial boost in your muscle size a preview of gains to come—which occur roughly six to eight weeks into a strength training program if you're a beginner, and eight to 12 weeks if you're more advanced, says Wilson. However, she says, 'this is going to look different for everyone because there are a lot of factors that play into muscle hypertrophy.' But there's another factor at play here. "Muscle definition is usually tied to things like body composition," Machowsky says. "Definition has to do more with your body composition than the strength itself." I.e., you can be stronger without looking "leaner," if you're not following a calorie deficit, so you're still the same weight. One of the biggest factors in expediting your gains, according to Wilson? Protein. 'Your daily protein intake plays an important role in muscle growth,' she says. Experts recommend aiming to consume 25 to 30 grams of protein per meal to promote healthy body composition and satiety. As for the training pattern to get you to that point, Wilson says that three to five strength training sessions per week, using six to 12 repetitions for three to five sets at 75 to 85 percent of your one-rep maximum (1RM), is your best bet. If you're not sure what your 1RM is, choose a weight that, on the final one to two reps, feels super-challenging but not impossible to do with proper form. Oh, and keep your rest in-between sets to no longer than 60 seconds, adds Wilson (this keeps the heart rate in that sweet spot to trigger physiological change). But what if your goal isn't to have bulging biceps—but to lift the heaviest possible weight you can (to build strength, not hypertrophy)? Once again, food comes into play big time, says Wilson. 'Think of your nutrition as your fuel,' she explains. 'If you're not eating enough calories to sufficiently fuel your body, you won't have the energy required to meet the maximal demands of strength training. If you want to improve strength, a calorie surplus is generally recommended.' (What this means: You'd generally need to be consuming more calories than you're burning.) As for the type of training that will get you to that point, Wilson recommends two to four sessions of strength training per week containing four to six sets of one to five reps at 85 to 100 percent of your 1RM, and three to five minutes of rest in-between each set. Resistance training helps you form lean mass, which "helps kind of tell your body to maintain its muscle as you lose weight," Machowsky adds. How Long It Takes To Lower Blood Pressure The verdict: Two to three weeks for modest improvement; four to 12 weeks for meaningful changes This health marker may not sound as hot as building muscle or knocking off a race PR, but it is oh so important to overall well-being. With a consistent workout routine (think at least four workouts a week that get your heart rate up), you can see a decrease in blood pressure and resting heart rate in as little as two to three weeks, according to N'Namdi Nelson, CSCS, an exercise physiologist at the NYU Langone Sports Performance Center. Here's how it works: As you increase your cardio capacity, you're exerting yourself, so your heart rate increases to pump blood around your bod faster. For example, when someone who's sedentary joins a HIIT class, their heart rate will shoot up very faster compared to someone with more aerobic training experience. Their cardiac muscles aren't used to the stimulus, so it results in a greater effect. However, as that same person works out more, their blood pressure will decrease, and as their body adjusts, so will their resting heart rate. Resting heart rate naturally follows. "The lower the resting heart rate, the better," says Nelson. Studies have shown that a low resting heart rate is linked with longevity, Nelson explains. A healthy resting heart rate to aim for is between 40 to 60. That's a sign of solid cardio health. If your heart rate is a bit higher, that's okay, However, a resting heart rate in the 80s or 90s is a sign you need more physical activity in your routine to bring it down, she adds. Keep in mind the two-to-three weeks timeline is on the speedy side. It may take four to 12 weeks to see the blood pressure and resting heart rate numbers drop, Machowsky adds. "You would need consistent activity for three months to feel like you can move the needle in an objective way," he says. (Think 20-30 minute sessions and five days a week of moderate aerobic activity or three days of higher intensity activity weekly, according to ACSM guidelines.) Like the other workout goals above, the time it takes to change blood pressure varies for each individual and how quickly someone responds to exercise, says Machowsky. How Long It Takes To Impact Mental Health The verdict: You can see immediate benefits, and long-term effects over four to six weeks Brace yourselves, as little as five minutes of moderate exercise can produce a mood boost, according to the American Psychological Association. That's right, five minutes to turn that frown upside down! It goes deeper with more time (four to six weeks), according to Nelson. "Research is very solid, showing that it is very helpful with helping fight depression and improving mood, and things like anxiety," Machowsky says. It also helps you become more confident when it comes to aesthetic ~gains~, Nelson adds. "Exercise releases endorphins and dopamine, both of which are associated with improved mood," says WH advisor Chloe Carmichael, PhD, a New York–based clinical psychologist. "The increase of feel-good chemicals in the question above improves the mood, which can mitigate anxiety and depression." Plus, when you commit to an exercise routine, it improves your sense of self-efficacy, or the sense that you can do what you say you do, according to Carmichael. These thoughts reinforce positivity, countering negative or depressive thoughts. "One of the hallmark features of depression is a sense of helplessness," so when you work out and increase these self-efficacy feelings you can potentially mitigate depression, Carmichael also eases feelings of anxiety because it "boosts our belief that we can handle challenges, she adds. Plus, it's a healthy outlet for stress.

Trump, tech giants want to make it easier to share health records: What it means for you
President Donald Trump and his top health officials are pursuing a new initiative that will allow people to share their personal health and medical records with doctors and hospitals. Technology giants Apple, Amazon, Google and Open AI as well as health industries companies UnitedHealth Group and CVS Health are among more than 60 companies that have agreed to develop standards to share health information across computer systems. Trump touted the idea of eliminating redundancies such as filling out paperwork at multiple health providers offices. "This will allow patients to easily transmit information from one doctor to another," Trump said during a July 30 briefing with Health and Human Services Secretary Robert F. Kennedy Jr. and Centers for Medicare & Medicaid Services Administrator Mehmet Oz. Trump emphasized the initiative will be voluntary and require patients to opt in. He added there will be no centralized, government-run database storing patients' personal records. "People are very concerned about the personal records," Trump said. "That's their choice ... it will be absolutely quiet." Large hospital systems and some doctors allow patients to share health information, fill out forms and schedule appointments through websites and mobile apps. And health tech companies have developed apps that allow people to track their health information, but these apps often can't access medical records from health providers, said Amy Gleason, acting administrator of the Department of Government Efficiency, or DOGE. Companies operating 21 networks have agreed to an "interoperability framework" to meet Centers for Medicare & Medicaid Services criteria, according to the Trump administration. Hospital systems and electronic health records vendors have agreed to cooperate in the effort, according to CMS. Participating apps would help people manage obesity and diabetes, including the use of AI assistants to help check symptoms or schedule appointments, CMS said. Privacy, data security remain top worries The health care industry and tech companies have been attempting to reduce paperwork and seamlessly share electronic health records for three decades, said Chris Pierson, CEO of BlackCloak, an Orlando, Florida-based cybersecurity company. Hospitals, doctors, labs and vendors that directly handle such sensitive medical records are subject to a federal privacy law, called the Health Insurance Portability and Accountability Act, or HIPAA. To make health information and records more portable and accessible, consumers need to be guaranteed strong privacy protections and granted control over what information is shared, Pierson said. A consumer might be willing to share their sensitive information with doctors, hospitals or labs. But the same person might want to block an app from sharing records with third parties such as exercise equipment vendors or nutritional supplement retailers. Pierson said such apps would likely still need to comply with HIPAA and other federal and state laws. Given that the apps are voluntary and require consent, they likely would comply with privacy laws, Pierson said. Companies also would need to safeguard information technology security to protect the sensitive information from data breaches. Hackers target health records Digital medical records are a popular target for hackers seeking sensitive health information, bank records and a person's identifiable information such as dates of birth and Social Security numbers. The number of attacks has surged in recent years and are often carried out by organized hackers, often operating overseas, who target the computer systems of health providers and the vendors and companies that serve them. HHS investigates whether breaches involve violations of health information privacy and security laws and publicly reports attacks that affect 500 or more on its website. In July alone, more than two dozen data breaches compromised the records of more than 3 million people, HHS records show. The largest hack in recent years involved the February 2024 attack on UnitedHealth-owned subsidiary Change Healthcare. The attack disrupted the health care industry because doctors and hospitals were unable to collect payments for weeks when computer systems went down.
