A groundbreaking new study reveals that just five minutes of eccentric exercise each day can significantly improve strength, flexibility, and mental well-being in people who previously led mostly sedentary lives. The findings, published in the European Journal of Applied Physiology in March 2025, challenge the notion that effective exercise requires a big time commitment—offering a practical path to better health for busy Thais grappling with limited time and space for fitness.
Eccentric exercise may sound unusual, but it’s simply the muscle-lengthening part of common movements—like the “down” dip during a squat or when lowering yourself in a push-up. In these new findings led by researchers at Edith Cowan University in Australia, participants spent two weeks maintaining their normal routines, then completed a 4-week program of just one slow set each of chair squats, chair reclines, wall push-ups, and heel drops every day. The key twist: each “down” phase was slowed to five seconds, while the “up” was performed in a single second.
Why does this matter to readers in Thailand? Many people here—just like in other parts of the world—struggle to find time, motivation, or access to equipment needed for lengthy or strenuous workouts. Thai office workers especially can spend long hours hunched over desks or in traffic, which contributes to stiff joints and weak muscles. With illnesses like obesity, diabetes, and depression on the rise in the Kingdom, accessible exercise regimens offer hope for improving both physical and mental health among those who feel they cannot “fit in” fitness.
During the study, 22 sedentary adults aged 32 to 69 performed these slow-movement workouts—either at once or spread throughout their day. They tracked steps with FitBits, underwent strength and endurance tests, and filled out wellness surveys before and after the program. Results showed big gains in several areas: participants improved lower body strength, push-up and sit-up endurance, flexibility, and cardiovascular fitness, even though there were no major changes in weight, blood markers, or hand grip strength. Most compelling was the mental health boost: 81% felt stronger, 71% felt fitter, and 78% said they felt healthier overall. Nearly 90% enjoyed the program, and none said they planned to stop exercising afterward, with most reporting new confidence and motivation (“reduced perceived time burden” was a key reason for their adherence) The Well News.
How did these short sessions stack up against other, more traditional programs? Previous research supports these results, showing that the eccentric phase of exercise, where the muscle lengthens under tension, is most effective for muscle growth—known as hypertrophy—and enhances flexibility NDTV, PubMed. Importantly, eccentric movements are easier for beginners than explosive or high-intensity efforts, which makes it more likely that people will stick with the program, a finding supported by the more than 80% of participants who stayed engaged Medical XPress.
Expert opinions echo these findings. Dr. Ken Nosaka, an exercise expert at Edith Cowan University, has long advocated for the inclusion of eccentric training in both clinical and home settings, noting, “What’s most encouraging is how even such a small commitment leads to measurable health improvements, which could help people adopt a more active lifestyle over time.” Thai personal trainers such as Sakda Teerachai add, “This approach is perfect for Bangkokians pressed for time or for seniors who want a gentle but effective way to improve strength without heavy weights.”
Looking at the wider context, Thailand already faces an aging population with increases in lifestyle-related diseases. Simple movement programs that do not require equipment or gym membership are well suited for local apartment living or even breaks in office settings—ใส่ใจสุขภาพได้แม้อยู่ในคอนโด (“you can care for your health even in a condominium”). The study’s participants themselves gradually chose harder versions of the exercises as they got stronger, moving from chair squats to single-leg squats, and many started considering other activities (yoga, resistance training, cardio) after completing the four weeks—a sign of building long-term positive habits. This echoes traditional Thai health wisdom about moderation and steady progress, found in sayings like ค่อยเป็นค่อยไป (“go slowly but surely”).
Historical context helps us understand the impact: Thailand has a strong tradition of community exercise, from early morning aerobic groups in parks to the popularity of Muay Thai. However, modern life is eroding participation. Programs like “5-10-15 สุขภาพดี” (“5-10-15 Good Health”), which encourage short bursts of daily movement, are gaining popularity and dovetail with the latest ECC (eccentric) research, providing “bite-sized” activity guides for the public.
What does the future hold if more Thais adopt this method? The long-term health benefits could be substantial, especially if small successes motivate people to move more. Medical experts point to the principle of specificity: the body gets stronger in whichever motions it routinely practices. Eccentric training, with its ability to build muscle, flexibility, and endurance (without high injury risk), is likely to be a key tool in preventing frailty as Thailand’s population ages Health. It also supports recovery from periods of inactivity—a major issue during the COVID-19 pandemic lockdowns and for desk-bound workers Medical XPress.
Scientific reviews highlight another benefit: eccentric exercise is particularly good at resisting injury and jump-starting adaptation, thanks to the “Repeated Bout Effect” that builds muscle memory and resilience over time PubMed, 2024.
For practical action, Thai readers are encouraged to try 5-minute routines of slow, controlled squats, push-ups against the wall, and gentle heel drops. No equipment or large space are needed—just a commitment to go slowly on the “down” phase, aiming for five seconds per lowering motion. Experts recommend starting simply and gradually progressing to more challenging options as confidence and strength improve. Importantly, consult a doctor before making changes if you have health concerns, and remember that the key goal is to create a regular habit—making fitness a natural part of everyday life, just like the Thai proverb สุขภาพดีไม่มีขาย อยากได้ต้องทำเอง (“Good health can’t be bought—you have to create it yourself”).
