A celebrity personal trainer thought she had to do intense cardio to see results. Now, she strength trains and walks instead — and looks and feels better.
  • The personal trainer Sana Shirvani used to regularly do intense workouts and restrict her diet.
  • She ended up burned out, so shifted her focus to strength training and eating a balanced diet.
  • Shirvani said she feels better physically and mentally.

Personal trainer Sana Shirvani learned the hard way that pushing her body more and more doesn’t yield better results.

The London-based trainer, whose clients include Halle Bailey and her fellow cast members of the 2023 live-action remake of “The Little Mermaid,” told Business Insider that doing too much intense exercise of varying types burned her out.

“I was always that gym bunny who would go to a million HIIT classes and completely batter myself and think that’s the right way to get results,” Shirvani, 32, said.

“I always used to pour from an empty cup. I’d have multiple burnouts a year and it got to a point in 2022 where I had such a bad burnout that it took me six months to recover,” she added.

Her approach to fitness has evolved “massively” since then. Seeking help from other trainers to reduce her workload, having a less restrictive diet, focusing on longevity, and replacing HIIT with strength training and low-intensity cardio have helped her feel better about her appearance and feel less anxious and stressed, she said.

“It was such a big wake-up call for me,” Shirvani said. “I was mentally really not in a good place for a long time.”

Shirvani is among those who have realized in recent years that more is not always better when it comes to fitness. Focusing on recovery has become more important to many, reflected by the increasing demand for smartwatches and rings that measure how well you’ve recovered as well as moved.

Here’s how Shirvani’s priorities have changed.

Low-intensity exercise to minimize stress

While short spells of intense exercise can bring health benefits such as improved cardiovascular fitness, research suggests multiple, long HIIT classes each week can put stress on the body. However, personal thresholds vary depending on lifestyle, stress, and fitness levels.

Instead of regular hardcore workouts, Shirvani does low-intensity steady state (LISS) cardio, such as walking, climbing on a stair master, or incline walking on a treadmill.

She uses the time to relax and listen to a podcast or just be with her thoughts.

Strength training for longevity

Shirvani does a minimum of four resistance training sessions a week — two lower body, two upper body — and a full body workout, plus rehab exercises if she has time for a fifth session.

Strength training has helped Shirvani build muscle, but her health is a bigger priority than her appearance. She wants to continue moving well and being pain-free and preparing her body for potentially carrying a child, as well as the menopause. She hopes the workouts will prevent age-related muscle loss, and maintain joint health, balance, and stability, she said.

Research shows that strength training is crucial for healthy aging as it helps combat age-related muscle and bone density loss.

“Every single human on this planet should be strength training in some sort of capacity,” Shirvani said.

However, she stresses that as someone without children who works in the fitness industry, her routine may not be manageable for most people.

“You can still reap those benefits with two or three weekly strength training sessions,” she said.

Eating a balance of protein, carbs, and fats

Shirvani used to think she had to eat plain meals like chicken, broccoli, and rice and stick to “crazy” calorie deficits to be healthy and leaner.

Now, she feels better for eating more and has learned that she can make nutritionally balanced dishes that are flavorsome using spices and sauces.

Shirvani doesn’t eliminate any foods, and still enjoys chocolate and desserts.

“Moderation is such an annoying word, but it’s genuinely everything in moderation,” Shirvani said. “Food is there to be enjoyed.”

Eating enough protein is her priority because it helps her body recover from workouts. Her staple meals include chicken salads topped with cheese, shepherd’s pie, and homemade turkey burgers.

She’s also started paying more attention to her energy levels as she’s got older. On days when she ate a high-carb breakfast, such as a bowl of oatmeal, she found she was hungry a couple of hours later and felt her energy levels slump.

In contrast, when she has a high-fat and high-protein breakfast, she feels satiated for longer.

“This is so personal though, this does not apply to every single person. I know people who have oats in the morning and they’ve got so much energy,” Shirvani said.

Sleeping for recovery

Sleeping well is Shirvani’s top priority when it comes to recovery, and for that reason, she never goes on her phone in bed.

“That’s helped me massively,” she said.

Research suggests that blue light exposure from screens such as phones could disrupt sleep.

Shirvani takes saunas when she can to relax in the evening. She always gives herself time to wind down before sleeping, rather than working late and going straight from emails to bed, she said.

She’s also a fan of offloading her brain through journalling and ice baths a couple of times per week.

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.
