Thai runners could shave minutes off race times by embracing VO2 max-focused training, new research and expert guidance suggest. Recent fitness analyses indicate that high-intensity interval training (HIIT) and targeted interval runs can lift VO2 max—the body’s maximum rate of oxygen use during intense effort—within about six weeks. For a country where heat, humidity, and crowded urban landscapes pose unique training challenges, these findings offer a practical path to faster pace without endless mileage.

In glossy studios across Bangkok and beyond, the hottest trend isn’t just the music or the mirrors—it’s the temperature. Hot workout classes, from heated yoga to high-intensity interval sessions in warm rooms, have surged in popularity as gym chains tout benefits from increased calorie burn to better flexibility. But the latest research reveals a more nuanced picture: heat can alter how hard the body works, improve heat tolerance with regular exposure, and sometimes blunt the gains you’d expect from exercise in cooler air. For Thai readers, where outdoor heat and monsoon humidity already test the body, these findings matter for everyday fitness, public health messaging, and the design of exercise spaces in our own communities.

A growing body of international sports science warns that five popular exercises undermine muscle growth across Thailand’s expanding fitness scene. Led by evidence-based training expert Dr. Mike Israetel, this analysis highlights movements that often seem beneficial but hinder hypertrophy, offering important implications for Thailand’s wellness sector and the millions pursuing strength training goals.

Thailand’s fitness market has boomed from Bangkok’s city centers to provincial towns, with social media-driven trends shaping practices. While Western methods influence many enthusiasts, Thai culture also emphasizes functional movement and martial arts, making scientifically guided exercise selection crucial for real progress. For many gym-goers—from urban professionals to university students in Chiang Mai, Phuket, and Khon Kaen—the challenge is translating popularity into measurable results amid busy lives and finite recovery time.

Leading international sports scientists have issued urgent warnings about five extremely popular exercises that are actively undermining muscle-building efforts across Thailand’s rapidly expanding fitness industry, potentially wasting millions of baht and countless hours that Thai gym-goers invest seeking meaningful physical transformations. This comprehensive scientific analysis, spearheaded by renowned evidence-based training expert Dr. Mike Israetel and recently featured in major international fitness publications, identifies specific exercises that appear beneficial but actually hinder hypertrophy progress—a revelation with profound implications for Thailand’s booming wellness sector and the millions of Thais pursuing strength training goals.

A new wave of scrutiny has hit the weight room as top sports scientists call out some of the most popular exercises for muscle hypertrophy—highlighting that certain so-called “smart” moves may actually be holding Thai fitness enthusiasts back from real muscle growth. In a recent feature published on July 30 by Men’s Health UK, sports scientist Dr Mike Israetel, a revered voice in evidence-based strength training, candidly declared five commonplace exercises as “bottom tier” choices for anyone serious about building muscle mass. With exercise trends from YouTube to Thai gyms shaped by global fitness fads, these insights have major implications for how locals plan their resistance programs—and how they can avoid wasting precious gym time.

A landmark study has shattered the myth that hours in the gym are necessary for effective muscle growth, revealing that only thirty minutes of targeted resistance training twice a week is enough for significant results. This breakthrough comes from an eight-week clinical trial led by an exercise scientist at Lehman College and published in Medicine & Science in Sports & Exercise, offering new hope to time-starved Thais eager to improve their health without upending busy schedules (Earth.com).

A recent eight-week study shows you can build noticeable muscle with just two 30-minute resistance workouts each week. Conducted by researchers at Lehman College and published in Medicine & Science in Sports & Exercise, the findings challenge the idea that long gym hours are essential. For busy professionals, students, and older adults in Thailand, this offers a practical path to better health without major schedule changes.

The trial involved 42 experienced lifters who were not professional athletes. Participants completed a core routine of nine movements—squats, rows, lat pulldowns, leg presses, and more—twice weekly. Each session lasted exactly 30 minutes, including warm-ups and brief rests. Half trained to absolute failure, the other half stopped two reps short as a safety measure. After eight weeks, both groups showed similar gains in muscle size and strength.

A recent study from the Capital University of Physical Education and Sports in Beijing has drawn global attention by showing that the order of workouts may influence fat loss, especially visceral fat linked to heart disease and other chronic conditions. For Thai readers, these findings offer practical insights to optimize gym routines with science-backed strategies.

The study, announced in mid-June 2025, followed 45 overweight men aged 18-30 over 12 weeks. Participants were assigned to three groups: cycling before resistance training, resistance training before cycling, or continuing their usual activity as a control. After three months, both exercise groups lost weight and gained muscle, but the weights-first group achieved notably greater reductions in total and visceral fat.

A new study led by researchers at the Capital University of Physical Education and Sports in Beijing has sparked interest worldwide, suggesting that the order in which we exercise may make a substantial difference in fat loss—especially the harmful visceral fat associated with heart disease and other chronic illnesses. For Thai readers seeking to optimise their gym routines or find science-backed weight management strategies, these findings shed light on simple tweaks that could lead to more effective fat burning and better health outcomes.

A groundbreaking 12-year study tracking over 14,000 adults aged 50 and above has revealed that building muscle strength, rather than simply prioritizing aerobic exercise, is essential for living longer. Published in the Journal of Strength and Conditioning Research, the study measured participants’ grip strength—a simple but reliable indicator of overall muscle health—and linked it directly to risk of early death. Adults with weaker grip strength were found to have a 45% higher risk of mortality over the study period, challenging conventional advice that places cardio at the centre of healthy aging regimes (Tom’s Guide).

A 12-year study tracking more than 14,000 adults aged 50 and above shows that building muscle strength matters more for longevity than cardio alone. The research used grip strength as a simple indicator of overall muscle health and found that weaker grip was associated with a 45% higher risk of death during the study period. The finding challenges traditional aging advice that centers cardio as the main path to a longer life.

A new study from the University of New South Wales in Sydney challenges the idea that creatine supplementation reliably boosts muscle growth. The findings suggest that, for some individuals, adding creatine to a three-month weightlifting program may not lead to bigger muscles compared with training alone.

The research drew broad media attention by testing participants in a structured resistance training plan. Results showed no significant difference in muscle mass gains between those who took creatine and those who did not. While creatine remains popular among athletes and gym-goers for potential performance benefits, this study invites a more nuanced view of its role in hypertrophy.

A recent study conducted by researchers from the University of New South Wales (UNSW) in Sydney, Australia, has stirred the fitness community, questioning the long-held belief that creatine supplementation significantly boosts muscle growth. Despite creatine’s popularity among athletes and gym-goers as a performance-enhancing supplement, this new research suggests that its efficacy in building additional muscle mass may be overestimated.

The UNSW study, which gained substantial media attention, involved participants engaged in a structured three-month weightlifting program. Surprisingly, the findings indicated no significant difference in muscle mass gain between those who supplemented with creatine and those who did not. The study’s results challenge the conventional wisdom that has fueled the widespread use of creatine among bodybuilders and athletes aiming to maximize muscle hypertrophy.
