A 70-year-old cardiologist and longevity expert now emphasizes strength training as the missing piece in a lifetime of aerobic exercise. In a recent interview with TODAY, he admitted that focusing mainly on running and cycling made him overlook resistance work. After a year of dedicating at least an hour of strength training three times per week (or shorter sessions more often), he reports greater strength and fitness than in his younger years. “If I’m going to be old, I’d rather be strong and old,” he said, a message that resonates with Thailand’s rapidly aging population.

A growing body of research and expert analysis warns that High-Intensity Interval Training (HIIT)—long promoted as the ultimate quick and efficient fitness solution—may pose serious health risks for adults over 50. As Thailand’s population ages, understanding which exercises truly benefit longevity and wellbeing is critical for turning back the clock not just on the surface, but deep within our bodies.

The concern over HIIT and similar high-intensity workouts lies in how older bodies respond to extreme exercise. According to the recent article published by Journee Mondiale (journee-mondiale.com), fitness professionals and medical researchers no longer consider HIIT universally safe for the over-50 crowd. The main culprit appears to be the body’s stress response: HIIT can trigger a surge in cortisol, the so-called ‘stress hormone.’ For adults over 50—especially women undergoing menopause—this cortisol spike may amplify hormonal imbalances, contribute to sleep issues, spark chronic inflammation, and promote fat accumulation around the waist, all maladies already associated with aging. Sports medicine specialists note that the long-term elevation of cortisol could counteract the cardiovascular benefits of exercise, raising the risk of heart problems.

A growing body of research warns that high-intensity interval training (HIIT) may not be the universal best choice for adults over 50. As Thailand’s population ages, it’s essential to identify exercises that truly support longevity and well-being for longer, healthier lives.

Experts say the body’s response to extreme effort changes with age. A recent analysis suggests HIIT is not universally safe for those over 50. The primary concern is the stress response: HIIT can trigger a spike in cortisol, the body’s stress hormone. For people approaching or beyond menopause, this cortisol surge can worsen hormonal imbalances, disrupt sleep, promote chronic inflammation, and encourage fat accumulation around the waist. Over time, sustained cortisol elevation may blunt cardiovascular benefits and raise heart risk.

New research is shedding light on the fascinating cognitive benefits that come from regularly using your non-dominant hand—a practice that could bring fresh hope for brain health and manual dexterity, from the kitchen table in Bangkok to rehabilitation clinics worldwide. While it may seem like a minor challenge, switching hands for everyday tasks is backed by compelling scientific evidence showing that this novel training helps activate underused parts of the brain and refine motor skills. Experts say that both the short- and long-term benefits, from sharper focus to improved brain connectivity, could make this small shift a surprisingly impactful part of daily life—especially for Thai readers interested in lifelong learning and healthy aging.

New research suggests that regularly using your non-dominant hand can boost brain health and manual dexterity. This small daily habit could support healthy aging and rehabilitation, from Bangkok kitchens to clinics across Thailand. The evidence indicates that switching hands for common tasks engages underused brain regions and enhances motor skill control. Both short- and long-term benefits — improved focus, quicker reactions, and stronger brain connectivity — may make this a practical addition to daily routines.

A groundbreaking 12-year study has revealed that building and maintaining muscle strength, rather than focusing solely on cardio exercises, could be the best strategy for living a longer and healthier life. Published in the Journal of Strength and Conditioning Research, the large-scale research tracked over 14,000 adults aged 50 and older and found a surprisingly strong link between grip strength—a simple measure of overall muscle health—and mortality risk, challenging prevailing beliefs about the sole significance of cardiovascular workouts for longevity.

A new wave in fitness is gaining traction globally — and it’s as simple as walking, but with a twist. The Japanese interval walking method, now popular on social media and the subject of emerging scientific research, promises to boost cardiovascular health, reduce blood pressure, increase muscle strength, and support overall well-being through a simple but structured walking routine.

Originating in Japan as Interval Walking Training (IWT), this approach alternates short bursts of high-intensity walking with periods of slower-paced recovery. Proponents say it’s a smarter way to walk, delivering health results often associated with more strenuous exercise — and recent anecdotal reports, like one published by Tom’s Guide, suggest the method is accessible and enjoyable enough for sustained practice (Tom’s Guide).

A simple activity is catching global attention: walking with purpose. The Japanese interval walking method breaks walking into short, brisk bursts followed by recovery, delivering noticeable health benefits. Enthusiasts say it’s approachable, enjoyable, and effective for cardiovascular health, blood pressure, strength, and overall well-being.

IWT originated in Japan as Interval Walking Training. It alternates three minutes of brisk walking with three minutes of relaxed pace. This cycle lasts about 30 minutes and is recommended three to four times per week. The approach emphasizes structure over sheer volume, contrasting with the traditional 10,000-step target. Proponents argue that it offers a smarter way to walk and achieve fitness gains tied to more intensive activity.

A large 12-year study suggests that building and maintaining muscle strength may be more important for a longer, healthier life than cardio alone. The research followed more than 14,000 adults aged 50 and older and found a strong link between grip strength and death risk. Grip strength, a quick measure of overall muscle health, emerged as a practical predictor of longevity.

For Thai audiences navigating endless longevity tips online, this study offers clear, actionable insight. While common advice focuses on steps, protein, or sleep, grip strength provides a simple, modifiable target. The study found that participants with weaker grip strength faced about a 45% higher risk of death during the study period. Data from Thailand’s aging population makes this especially relevant: the World Health Organization projects that those aged 65 and older will constitute around 20% of Thailand’s population by 2040, signaling rapid demographic change and a need for practical health strategies.

The Japanese walking method, also known as Japanese Interval Walking Training (IWT), has become one of the latest global health trends, captivating both fitness enthusiasts and health experts alike. The method—which alternates three minutes of low-intensity walking with three minutes of higher-intensity walking, repeated for a total of 30 minutes—has shown promise not only as an accessible workout, but also as a scientifically backed approach to improving cardiovascular health, metabolic function, and overall wellbeing. As this movement continues to gain adherents worldwide, recent research underscores its potential, particularly for Thai society grappling with rising rates of non-communicable diseases.

A simple walking routine is catching global attention: the Japanese Interval Walking Training (IWT). This approach alternates three minutes of easy walking with three minutes of brisk effort, repeated for a total of 30 minutes. Studies suggest it can improve cardiovascular health, metabolic function, and overall wellbeing. As Thailand faces rising rates of non-communicable diseases, IWT offers an accessible, evidence-based option that fits urban life.

Originating in Japan, IWT was designed as a public-friendly form of high-intensity interval training. It does not require special equipment or venues. Parks, sidewalks, and indoor spaces are all suitable. This makes IWT especially adaptable for busy Bangkok streets or village paths across Thailand.

Pelvic floor health is often misunderstood, but new research and expert guidance are reshaping how people approach this topic. A recent Guardian piece highlights five common myths about pelvic floor care and offers evidence-based takeaways that are highly relevant for Thai readers.

The pelvic floor is a key group of muscles at the base of the pelvis. These muscles support the bladder, bowel, and reproductive organs, and they play a crucial role in continence, sexual health, and spinal stability. Many people remain unaware of their function until problems arise. Health professionals note that education about pelvic health is limited across ages, which can delay seeking help.

Pelvic floor health has long been shrouded in misconceptions, with a new wave of research and expert opinion now challenging what many take for granted—especially the belief that Kegel exercises are the universal remedy. A recent article from The Guardian, released on 20 May 2025, shines a spotlight on five prevailing myths surrounding pelvic floor care and offers evidence-based insights that could reshape how people in Thailand think about their own well-being The Guardian.

A personal experiment has sparked global discussion about static holds in fitness. After ten days of daily isometric core work, a writer reported a dramatic doubling of core strength. The result has drawn interest from researchers and fitness experts and now resonates with Thai readers who favor practical, low-cost health strategies.

Static holds, or isometric exercises, keep the body in a fixed position with no joint movement. Observations from a detailed account show forearm planks, side planks, and hollow-body holds led to nearly doubled plank endurance and improved stability, with less lower back discomfort. This rapid progress challenges the idea that strength must grow slowly, prompting ongoing scientific debate.

A recent firsthand experiment has ignited global interest—and scientific debate—about the power of static holds in fitness training. After just ten days of performing isometric core exercises, a writer reported a dramatic doubling of core strength, a result that has not only surprised fitness enthusiasts but is now being substantiated by research and expert opinion. For Thai readers, familiar with both traditional bodyweight exercises and contemporary health trends, this news points to a practical, low-cost strategy for improving core stability, posture, and overall wellbeing.

A short, daily brisk walk could sharpen mental faculties as people age. Recent international findings from researchers at the University of South Australia and AdventHealth Research Institute show that even five minutes of moderate-to-vigorous activity can boost cognitive function in older adults. The study, published in Age and Ageing, analyzed how daily activity patterns relate to cognitive performance, including processing speed, working memory, and executive function.

Thailand is rapidly aging, and experts stress the urgency of practical ways to preserve cognition. The World Health Organization notes that by 2030, one in six people globally will be 60 or older. In Thailand, more than one in five residents are over 60, underscoring the need for accessible health strategies as families manage senior care and public budgets respond to rising demand. The new findings offer a simple path: small, purposeful bursts of activity can yield meaningful brain benefits.

A brisk five-minute walk may be all it takes to give your brain a cognitive boost as you age, according to a groundbreaking international study just released by researchers at the University of South Australia and AdventHealth Research Institute. The findings, published on April 4, 2025, in the journal Age and Ageing, shed light on how even modest bursts of moderate-to-vigorous physical activity—such as quick-paced walking or light jogging—can significantly improve mental agility in older adults (source).

A groundbreaking new study has revealed that women gain more substantial mortality and cardiovascular benefits from exercise compared to men—and can do so with less time spent working out. This research, published in 2024 in the Journal of the American College of Cardiology, sheds new light on how physical activity impacts health differently based on sex, prompting calls for women in Thailand and worldwide to make exercise a non-negotiable part of daily life.

A recent feature highlights the soleus, a small but mighty calf muscle that powers runners through every step. In Thailand’s vibrant running scene, coaches say attention to the soleus can boost performance and cut injury risk, complementing the usual emphasis on glutes and hamstrings.

Experts explain that the soleus stays active throughout the gait cycle, helping absorb impact and propel the body forward. It may carry up to 80% of the force generated by the calf muscles. Yet many runners neglect targeted soleus training, potentially limiting efficiency and elevating injury risk.

A recent feature in Fit&Well shines a spotlight on the soleus muscle, a crucial yet often neglected muscle in the lower leg that plays a pivotal role for runners and active individuals of all levels. While most fitness routines for runners in Thailand focus on strengthening the glutes and hamstrings, a prominent running coach emphasizes that the soleus is arguably the most important muscle for performance and injury prevention—a point especially relevant for the Kingdom’s vibrant running community and the rising popularity of marathon events nationwide (Fit&Well).

New research shows women gain greater mortality and cardiovascular benefits from exercise than men, and they can achieve these gains with less time. The study, published in 2024 by a leading cardiovascular journal, highlights sex-specific responses to physical activity and underscores exercise as a daily health priority for women in Thailand and around the world.

The study analyzed health data from over 412,000 American adults aged 27 to 61, collected between 1997 and 2017. Researchers linked activity patterns to mortality outcomes through national records up to 2019. Findings reveal that women who reach at least 150 minutes of moderate-to-vigorous activity weekly cut their all-cause death risk by up to 24 percent, compared with inactive women. In men, the reduction was about 15 percent at the same activity level. Notably, women achieved equivalent benefits with roughly 140 minutes, compared with men needing about 300 minutes, indicating higher efficiency of activity for female physiology.

Anyone who has rushed up Bangkok stairs or temple steps may have wondered why the ascent takes the wind out of them. New insights from fitness science show that getting winded on stairs is not a sign of poor health or low fitness. Rather, stair-induced breathlessness is a normal response as the body switches from rest to sudden, high-intensity effort.

For Thais working in vertical environments—from bustling transit hubs to multi-story shopping centers and hillside temples—this understanding is especially meaningful. Breathlessness on stairs is common and not something to fear. Recognizing this helps people set realistic health expectations and adopt practical steps to improve.

A new research study from Uppsala University sheds fresh light on the long-held belief that higher physical fitness dramatically reduces the risk of premature death, suggesting these benefits might not be as substantial as previously thought. The findings challenge established wisdom in the fields of health and public policy, carrying important implications for how Thai society and policymakers approach physical activity initiatives (Uppsala University).

The prevailing narrative—supported by countless observational studies—has been that individuals with higher fitness are far less likely to die prematurely from causes such as cardiovascular disease, cancer, or all causes combined. The new investigation, however, warns that these links may be significantly overstated due to hidden factors in earlier research designs, and highlights the need for a more nuanced conversation as Thailand continues its campaigns promoting widespread exercise and healthy living.

A large new study from Uppsala University questions the extent to which higher physical fitness lowers the risk of early death. While fitness remains important for health, the researchers caution that the life-extending effects shown in earlier studies may be overstated due to hidden factors in observational designs. This has clear implications for Thailand’s public health messaging and activity programs.

Traditional studies have linked higher fitness with markedly lower risks of cardiovascular disease, cancer, and death from all causes. In this study, researchers initially replicated those associations, noting substantial reductions in mortality among the fittest individuals. But they then applied a “negative control” approach—asking whether high fitness in adolescence also reduces deaths from random, unrelated accidents like car crashes or drownings. Surprisingly, the link persisted for accidental deaths as well, suggesting the observed associations could reflect other, unseen factors rather than fitness alone. As one senior researcher explained, observational studies can produce strong but misleading estimates if groups are not truly comparable.
