I did these 3 dumbbell exercises for summer-worthy arms — no gym required
What if just three exercises could help sculpt stronger, more defined arms in time for the summer? Good news — they can.
Well-defined arms can boost your confidence in the warmer months, but if your upper body isn't quite there yet, don't worry. Personal Trainer Dr. Robin Barrett from the Ladder workout app has designed a quick routine that delivers visible results in just five minutes a day.
This five-minute workout uses compound movements to engage multiple upper-body muscles simultaneously, targeting the biceps, triceps, shoulders, and upper back. No gym? No problem — all you need is a pair of the best adjustable dumbbells so you can scale the weight as you go.
'Dumbbells are a great way to challenge yourself with limited kit,' says Dr. Robin. 'They require you to stabilize the load and control the movement path, which makes the workout more effective. Plus, you can do a huge variety of exercises with them, which keeps things fun and helps you stay consistent — and that's how you get results.'
'This workout uses compound exercises that hit multiple muscle groups and push the upper body to total fatigue,' says Dr. Robin. 'You'll burn a lot of calories in a short amount of time.'
Use it on its own or pair it with other strength routines for a well-rounded program.
Perform one set of each exercise for 12–15 reps, back to back, with minimal rest between moves. Repeat the circuit three times. If you've got more time or energy, go for an extra round (or two)

Reps: 12–15
Why: This variation of the lateral raise rotates the wrists so your palms face up, increasing activation in the middle deltoids while also challenging grip and shoulder stability. It's a subtle shift that delivers a serious burn.
How:
Reps: 12–15 each side
Why: This move targets the front of the shoulders (anterior deltoids) while improving strength and stability. Alternating arms reduces fatigue and allows you to focus on good form.
How:
Reps: 12–15
Why: This combo move hits the shoulders, traps, and rotator cuff in one smooth sequence, improving both strength and mobility.

The proof is in the pudding — I'm proud of my sculpted arms, and enjoyed adding this workout to my routine for a week. There's no complicated routine or heavy weights — just a set of dumbbells and a few focused moves.
My arms burned as I got to the final few reps, but at just five minutes long, it was over before I knew it. I love the confidence sculpted biceps, triceps, and shoulders give me. What are you waiting for? Grab a set of dumbbells and give this one a go.

New Genetic Test Could Diagnose Brain Tumours in 2 Hours
Researchers at the University of Nottingham have developed a new genetic test that can diagnose brain tumours in as little as 2 hours The test, called ROBIN, uses PromethION nanopore sequencing to deliver rapid methylome classification. The researchers said results could be available intraoperatively, allowing clinicians to make faster, more informed decisions. The same assay can also be used for next-day molecular profiling, including detection of single nucleotide, copy number, and structural variants. DNA methylation-based classification is now essential for diagnosing and managing many brain tumour subtypes. Current diagnostic methods rely on additional microarray-based assays to detect pathognomonic somatic mutations and structural variants. These steps often delay final diagnosis. Delays Cause Distress and Postpone Treatment Due to the high capital costs, current analytic tests are restricted to specialist tertiary care centres with high throughput, requiring samples to be sent across regions. Tests are sent to centralised facilities, meaning that clinicians have to wait six to eight weeks or longer before they receive full results. This delay can cause significant anxiety for patients and postpone the start of treatment. New Test Offers 2-Hour Turnaround In a study published in Neuro-Oncology , the Nottingham team of scientists and medics tested ROBIN's classifier performance on 50 prospective intraoperative cases. ROBIN, a software tool based on the P2 PromethION nanopore sequencers The test achieved a diagnostic turnaround time under 2 hours. Tumour classification began within minutes of sequencing. It was able to detect single nucleotide variants, copy number variants, and structural variants in real time. In many cases, methylation classification and identification were achieved within a few hours of sequencing. In 90% of classifiable cases, the test provided a complete integrated diagnosis within 24 hours. Its classifications matched the final diagnosis in 90% of cases. ROBIN was able to provide a full integrated diagnosis, with a mean turnaround time of 24 hours for the ultra-fast pipeline. Classifier performance demonstrated concordance with the final integrated diagnosis in 90% of prospective cases. Researchers say nanopore sequencing can improve diagnostic turnaround and offer reliable, clinically actionable intraoperative classification. The test also requires minimal tissue, enabling diagnosis from small samples, such as those obtained via stereotactic biopsy. "Revolutionary" Speed and Accuracy Study co-author Dr Simon Paine, consultant neuropathologist at Nottingham University Hospital, noted both the speed and accuracy of the test. "It really is revolutionary," he said in a press release. According to Cancer Research UK, about 12,700 people are diagnosed with brain tumours annually in the UK. More than 5000 die each year Incidence has increased by 24% since the early 2000s. Ten-year survival remains low, at just 11%. The Nottingham team believes that ROBIN could significantly improve care for thousands of UK patients each year. The researchers hope to see the test adopted across NHS trusts. However, they stressed that clinical trials are needed to confirm its utility in routine practice. The BRAIN MATRIX trial, funded by The Brain Tumour Charity, will assess how ROBIN can help match patients to personalised clinical trials. Dr Simon Newman, chief scientific officer at the charity, said in a press release that rapid diagnosis could reduce uncertainty for patients and speed up access to care. 'The potential to combine so many separate tests into one and deliver at a local level is a game changer,' he said.

New brain tumour test a 'game changer', say experts
A new test has been developed that reduces the time it takes to diagnose types of brain tumours from weeks to just hours, researchers say. Surgeons have described the "ultra-rapid" method of genetic testing as a "game changer" and say it could improve care and treatment for thousands of patients. The method has been developed by scientists at the University of Nottingham in partnership with clinicians at Nottingham University Hospitals NHS Trust (NUH). The research has attracted interest from across the UK, with other NHS hospitals setting up their own testing alongside their existing regimes to gather more evidence about its effectiveness. A study published on Wednesday reveals the method has already been used in 50 operations at NUH and has had a 100% success rate in diagnosing the exact type of tumour. There are currently more than 100 identified types of brain tumour, and clinicians need to identify which kind a patient has to determine the most effective way to treat them. Traditionally, samples of tumours are extracted during surgery to be taken away, tested, and examined under a microscope in a pathology lab. While the process is mostly accurate, it can take up to eight weeks to definitively diagnose the type of tumour. Stuart Smith, NUH consultant neurosurgeon, said: "Sometimes once we do get the full diagnosis back from the laboratory, we realise it's a type of tumour that would really benefit from what we call more radical surgery to remove every last piece of tumour, if that hasn't been done at the first operation. "Sadly, sometimes that does mean a patient has to undergo a second, or sometimes even a third operation, to ensure that all the tumour that can be surgically removed has been." However, the new technique has seen results returned in as little as 90 minutes, and Mr Smith said it was possible to get a diagnosis while a patient was still in the operating theatre for their original procedure. It means surgeons would be able to perform more radical surgery, if needed, at the time. Mr Smith also said faster classification could allow patients to get radiation treatment or chemotherapy, more quickly, and that the quicker diagnoses often reduced the anxiety patients felt while waiting for test results. "It is a game changer," he added. Prof Matt Loose, a biologist at the University of Nottingham's School of Life Sciences, developed the new method using software dubbed ROBIN. Using nanopore genetic sequencing, he said, scientists are able to choose which parts of the DNA to look at in detail, delivering a faster result. He said: "Sadly most brain tumours are incredibly aggressive and waiting six to eight weeks, or however long, for every subsequent test may be too long for that patient. "Now we can get the results within hours and that can happen within an operation while a patient is still in theatre." Gemma's daughter Nancy was diagnosed with a brain tumour aged just one in 2023. The now two-year-old had two brain surgeries, then high-dose chemotherapy treatment to prevent the cancer from coming back. Gemma, from Castle Donington in Leicestershire, said: "From Nancy's first surgery to finding out what that tumour was, it was two weeks, and that was two weeks of pure hell and anxiety. "But to have it done that quick it could have saved her that extra brain surgery." Nancy is now in remission and has become the face of a national TV advert for Young Lives vs Cancer, a charity that supported the family during her treatment. Charles Trigg, who lives near Market Harborough in Leicestershire, was diagnosed with a stage four aggressive glioblastoma tumour in April. He was told his tumour was the size of a golf ball. The 45-year-old, who has been treated by Mr Smith, said: "To have knowledge is power and it could be the worst knowledge you have, but it gives you certainty, and having that certainty actually makes life a hell of a lot easier. "The fact they've been able to get back data very quickly that allows an extensive team of people to conduct detailed reviews feels like an amazing blend of science and medicine. "The pace is phenomenal, and it gives you that certainty and clarity, regardless of whether you like the information, I can't change the information, but what I can do, is take the information I've been given early - and absorb it, feel it and start to plan for the next stage." Brain tumours are the biggest cancer killer of children and adults under 40, according to The Brain Tumour Charity. Dr Simon Newman, the charity's chief scientific officer, said: "The delivery of an accurate diagnosis within hours of surgery will be transformative for all patients ensuring rapid access to the optimal standard of care and - crucially - removing the uncertainty patients face when having to wait weeks for their diagnosis and prognosis." Queen Elizabeth Hospital Birmingham, and Great Ormond Street Children's Hospital and Kings College Hospital in London, are among those now setting up their own testing of the method alongside their existing processes.
