Stark warning against fitness trend loved by Molly-Mae’s sister &Molly Smith

A FITNESS trainer has warned against a viral exercise trend loved by stars including Molly-Mae Hague’s sister Zoe, saying it could lead to “physiological shock”.

The Hyrox craze – dubbed a “race for everybody” by organisers – has swept the globe since the competition was launched in Germany in 2017, with millions of people now taking part in over 30 countries, including the UK and China.

Competitors are tasked with running 1 kilometre, before hitting a functional workout station of various different exercises – which is repeated eight times.

“(Hyrox is) designed to accommodate all participants and 99 per cent of our athletes reach the finish line,” it reads on the Hyrox website.

Following the race, participants appear on a leaderboard, which are then added up ahead of a World Championship at the end of the season.

Videos of the competitions regularly appear on TikTok, with Zoe and other famous faces including ex Love Island star Molly Smith and 90s popstar Suzanne Shaw sharing their own experiences on social media.

However, exercise pro and personal trainer Emma McCaffrey has warned against taking part in the competition if you’re a beginner, insisting it’s a “high-intensity competitive event” rather than a “starter programme”.

“Jumping from the sofa to a one km run and a functional station circuit repeated eight times is a massive physiological shock,” she told the Daily Mail.

Emma added that the loud music, “high-octane environment” and “influencer pressure to perform” often leads to beginners ignoring their body’s natural signals to stop.

“As we’ve seen with cases of heart stress and panic attacks, ‘powering through’ can have serious, even fatal, consequences when the cardiovascular system isn’t conditioned for that level of load,” she said.

Meanwhile, weight loss coach Rachael Sacerdoti called it a “recipe for burnout and injury”.

She added that people “suddenly exposing” their bodies to “high-force, high-velocity training” without the proper preparation and conditioning can lead to injuries – with problems in achilles, patella and rotator cuff among the most common.

“When you’re exhausted, your form breaks down, and that’s when injuries happen,” she warned.

“Most beginners don’t have the strength, technique or movement patterns to maintain good form under that level of fatigue.”

Among those who have suffered following a Hyrox event include fitness fan Ashley Whelan, who had a heart attack after his first-ever Hyrox event.

The 37-year-old had trained for months before the competition and, while he didn’t feel 100% on the day itself, he thought it was just “race day nerves”.

However, after he completed his last lap, his heart rate shot up to a whopping 220 beats per minute.

And once he’d finished the event, he started to experience pain in his chest, arm and back – with on-site paramedics quickly completing an ECG test which showed he was in the middle of a heart attack.

What your trainer choice says about you…

Deputy Fashion Editor, Abby McHale, says “the ‘in’ trainers to be seen in can move as quickly as the next big fashion trend”.

Adidas = fashion ‘sheep’

Adidas has taken over as the top ‘it’ trainer brand of the past few years and they don’t seem to be going anywhere anytime soon. 

Starting strong with the Sambas, a trainer which this year will have been around for 75 years, the trainer style became so popular that videos were going viral last year showing a multitude of people wearing them on the same train.

Skechers = boring

The American brand has been around on the footwear market for the best part of three decades, but has never been seen as the trendiest of trainers. No matter what celebrity has been promoting the product the brand still does come with a certain stigma.

Practicality is at the heart, cushioned soles, easy to slip on and breathable, they come with a lot of functions for those who think comfort is key. 

Vans = living in the past

Originally made as a skateboarding brand, it went mainstream in the 2000s with its classic black and white checker board trainers that were deemed the height of cool.

Whilst they were never the style of trainers worn to the likes of the gym, they were great worn with the likes of jeans, trousers and dresses for the skater girls. However these days they’ve fallen slightly off the radar, which means if you’re still wearing them you live in the past.

Hoka = fitness fanatic

A trainer brand specialising solely in running shoes the brand was launched in 2009 and has become a staple in runners wardrobes all across the world. 

Consistently voted as some of the best running shoes you can buy, they have trainers categorised depending on what kind of exercise you are doing, from road running to hiking and even recovery trainers.

And while they may be great when it comes to exercise, that is where they should stay.

Nike = millennial

A long standing competition with Adidas, Nike has also been one of the market leaders when it comes to trainers, with the Air Force 1’s being the brands best selling shoe of all time.

They may have been the in shoe back in 2018, but they’re not in 2025, meaning if you still rock a pair you want to keep to a trend but aren’t a stickler, you know a good made trainer when you see one and love the cleanliness the all white style brings. 

Veja = tight

The French footwear brand has been around since 2005 but only gained major popularity a few years ago.

They have been seen on every celebrity going, even royalty hopped on board the trend with both the Princess of Wales and the Duchess of Sussex seen out in a pair.

However, the buzz around these has now died down and the fashion crowd have moved onto their next pair of trainers. Meaning that those left wearing Veja’s are the kind of people who get their wear out of everything until it falls apart.  

He was rushed to hospital, and was found to have a left coronary artery blockage, for which doctors had to shock him with a defibrillator to try and get his heart to beat regularly again.

Ashley has since made a full recovery, but is now warning others to listen to their bodies while taking part in events such as Hyrox.

“It’s still up in the air as to why I got this clot but when I’ve looked into it, deep emotional stress and high-intensity exercise can cause it,” he said.

He said he credits the “strength of” his mind and body to get him through the terrifying health scare, and knows he is “so lucky to be alive”.

“I’m living proof that it can happen to ultra-fit people as well,” he added.

“It’s a case of listening to your body.”

Hyrox has been contacted for comment.

Group Exercise Boosts Cognition, Fitness in Dementia

Group Exercise Boosts Cognition, Fitness in Dementia

In a groundbreaking advancement poised to revolutionize dementia care, researchers have announced a comprehensive study protocol examining the influence of community-based structured group exercise programs on both cognitive and physical functions in older adults living with dementia. This randomized controlled trial, detailed in a recent publication slated for BMC Geriatrics in 2026, aims to explore the untapped potential of structured physical activity as a non-pharmacological intervention to slow cognitive decline and improve overall quality of life.

Dementia, a progressive neurodegenerative condition characterized by deteriorating memory, thinking, and motor skills, remains one of the most pressing global health challenges, especially as populations age worldwide. Traditional approaches have primarily focused on symptom management and pharmacological treatments, which often come with limited efficacy and undesirable side effects. Against this backdrop, physical exercise has emerged as a promising avenue, backed by neurobiological theories suggesting that physical activity may promote neuronal plasticity, enhanced cerebral blood flow, and reduced neuroinflammation.

The study underlines the importance of a community-based framework, which holds immense promise for scalability, accessibility, and sustained engagement. Community-based interventions leverage social support, environmental context, and local resources, creating an ecosystem that encourages consistency and motivation among older adults. It also introduces structured group exercise as opposed to individual exercise routines—infusing a social and interactive element believed to synergistically bolster cognitive engagement alongside physical exertion.

At its core, this research protocol delineates a comprehensive systematic design featuring randomization — the gold standard for clinical trials — ensuring that participants are evenly distributed among intervention and control groups to minimize bias. The intervention includes carefully tailored exercise regimens that combine aerobic, resistance, balance, and flexibility training. These multifaceted routines aim to target various physiological systems implicated in dementia progression, from cardiovascular health to motor coordination and muscle strength.

Emerging studies have shown that aerobic activities stimulate hippocampal neurogenesis, critical for memory and learning processes often impaired in dementia. Resistance training, meanwhile, supports muscular strength essential for daily activities, reducing fall risk and enhancing autonomy. Balance and flexibility exercises further contribute by improving proprioception and joint mobility, thereby mitigating mobility-related comorbidities. By integrating these elements into structured group calendars, researchers anticipate synergistic effects accumulating over the trial timeline.

Cognitively, the engagement associated with group exercise acts as a dual catalyst. Beyond the direct neuroprotective benefits of physical activity, the social interaction inherent in group settings stimulates cognitive domains such as attention, executive functions, and emotional regulation. Social isolation and loneliness have been consistently linked to accelerated cognitive decline; thus, group dynamics within this exercise framework may serve as a potent protective factor by nurturing community bonds and meaningful interpersonal connections.

The outcome measures designed for this trial span a range of validated neuropsychological and physical assessments. Cognitive outcomes include evaluations of global cognition, memory, executive function, and processing speed conducted via standardized instruments like the Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA). Physical parameters are meticulously assessed using tests such as gait speed, handgrip strength, and the Timed Up and Go (TUG) test, presenting a multidimensional view of functional status.

Importantly, the protocol emphasizes longitudinal follow-up to determine the persistence of any cognitive and physical benefits post-intervention, which is pivotal in discerning sustainable impacts rather than transient improvements. Additionally, the researchers have accounted for confounding variables including baseline physical activity levels, comorbidities, and medication use, thereby ensuring the robustness and generalizability of the findings.

The implications of positive outcomes from such a trial are vast. Demonstrated efficacy could reshape public health policies and clinical guidelines, reinforcing physical activity as an essential component of dementia management. Community centers, healthcare providers, and caregiving organizations might adapt to include tailored structured group exercise programs, thus democratizing access to an affordable, scalable intervention with minimal side effects.

Moreover, this research aligns with growing interdisciplinary perspectives that advocate for holistic management approaches — ones that incorporate biological, psychological, and social determinants of health. The integration of physical activity into care plans reinforces a paradigm shift from reactive to proactive and preventative models that empower older adults with dementia to maintain independence and dignity.

While challenges remain in delivering consistent, well-supervised exercise programs adapted to heterogeneous patient needs and functional capacities, this trial’s community-rooted design mitigates many logistical and motivational barriers. Leveraging local infrastructure and peer support creates a dynamic environment conducive to sustained participation—a crucial factor given historically high dropout rates in exercise interventions.

From a neurobiological standpoint, this initiative supports the evolving understanding of dementia as a modifiable disorder where lifestyle and environmental factors play significant roles. The interplay between exercise-induced neurotrophic factors such as brain-derived neurotrophic factor (BDNF), reduced oxidative stress, and enhanced cerebral angiogenesis may offer mechanistic insights into how structured physical activity slows neurodegenerative processes.

In conclusion, the launch of this randomized controlled trial heralds a promising avenue for dementia intervention research by meticulously investigating the dual benefits of physical exercise on cognitive and physical realms in a structured, community-based setting. Its innovative combination of rigorous scientific methodology and practical community implementation presents an exciting frontier in mitigating the global dementia burden.

For families, caregivers, healthcare professionals, and policymakers alike, this trial offers hope through a vision of dementia care that transcends pharmacological limitations and centers on empowering individuals via movement, social connection, and holistic well-being. The ultimate testament to this research will be its translation from protocol to practice—transforming insights into real-world impact.

Do you have sore hips? I asked a pain specialist why this happens and how to improve it

Hip soreness is a terribly common issue—it’s something that I certainly suffer with—so I’m always trying to get to the bottom of where this soreness originates from and what you can do about it.

According to Dr Shady Hassan, MD, an interventional pain and sports medicine physician and the founder of NefraHealth, immobility is the root cause of this discomfort.
