#MuscleSoreness

A growing body of research argues that pain after exercise is not a necessary sign of progress. While delayed onset muscle soreness (DOMS) often follows workouts, experts say it does not indicate better gains or optimal adaptation. This shift in thinking aligns with safer training practices and has clear implications for Thai athletes, students, and anyone pursuing healthier habits.

While gym culture has long linked effort with pain, researchers explain that discomfort can signal effort but is not a reliable measure of improvement. A leading voice from the University of Bath emphasizes that you may gain more with a touch of soreness, yet pain alone does not drive growth or health benefits. This nuanced view helps to separate effort from injury and to promote sustainable training patterns.

“Feel the burn” and “no pain, no gain” are common mantras in fitness circles, but new research is challenging the idea that muscle pain is a necessary marker of exercise progress. According to a recent feature published by The Guardian (theguardian.com), experts argue that while muscle discomfort—especially the delayed onset muscle soreness, or DOMS—often follows exercise, it is neither a prerequisite for gains nor always a sign of positive adaptation. This timely revelation aligns with growing global awareness around safe exercise practices and has direct implications for Thai fitness enthusiasts, athletes, and anyone embarking on a healthier lifestyle.

A new wave of medical research and expert consensus is dispelling age-old myths about muscle soreness following exercise and highlighting what it really means for health and fitness enthusiasts, including Thai readers exploring their own fitness journeys. Contrary to the popular adage “No pain, no gain,” the latest findings suggest that post-exercise soreness, known as delayed onset muscle soreness (DOMS), is neither a requirement for progress nor an indicator of workout success, challenging beliefs that have been glorified in both international pop culture and Thai fitness circles for decades (The Guardian).

New medical research and expert consensus debunk long-running myths about muscle soreness after exercise. For Thai readers, the message is clear: soreness is not required for progress, and pushing through pain can hinder gains. Contemporary science shows that delayed onset muscle soreness (DOMS) does not signal a successful workout or necessary adaptation.

DOMS typically emerges 12 to 24 hours after unfamiliar or strenuous activity, peaking between 24 and 72 hours, and then fading. The old belief that lactic acid buildup causes next-day soreness has been debunked. A clinical assistant professor at a leading US university notes that lactic acid is cleared within an hour after exercise and is not responsible for subsequent muscle ache. Instead, microtrauma in muscle fibers from new or intensified movements triggers a temporary inflammatory response that explains the discomfort.

Feeling sore after exercising is almost a rite of passage in fitness culture, but new research and a recent analysis by international experts reveal that muscle soreness isn’t the badge of honor many believe it to be—and it may not be necessary for fitness gains at all. For Thai readers increasingly participating in gyms, boot camps, or traditional Muay Thai classes, understanding the truth about post-workout pain could transform how the nation trains for both health and happiness.

Soreness after exercise is a familiar badge of effort, but new research challenges the idea that pain equals progress. For Thais flocking to gyms, Muay Thai classes, or community fitness sessions, understanding the truth about post-workout discomfort can reshape training for health and happiness.

The old “no pain, no gain” mindset has shaped attitudes toward fitness in Thailand and beyond. Delayed onset muscle soreness (DOMS) has long been seen as proof that muscles are learning and growing. Yet leading researchers say soreness is not required for fitness gains. As a senior clinician notes, soreness does not determine overall fitness level, and many effective workouts leave us feeling little to no DOMS. That means office workers in Bangkok joining evening classes and seniors joining community aerobics should not equate pain with progress.

Many athletes in Thailand rely on massage after workouts, hoping it speeds recovery and flushes lactic acid. New analyses, grounded in recent reporting and scientific studies, show massage clearly eases discomfort but not for the reasons many believe. The strongest effect tends to be psychological—what Thai readers might call the mental boost from feeling cared for and relaxed.

Research indicates massage provides tangible comfort after intense exercise, but the supposed physiological boons—rapid toxin removal or accelerated muscle recovery—are not strongly supported by evidence. A scholar from an Australian Catholic University highlights that athletes favor massage because it feels good, even though the robust physiological benefits remain unproven. In other words, massage is a popular aid for mood and perception, not a guaranteed engine of physical recovery.

Many athletes and fitness enthusiasts turn to massage as their primary recovery strategy after a hard workout, convinced it aids muscle recovery and removes lactic acid from their bodies. However, recent research reveals that while massages do offer real relief, the underlying reasons might differ from what most people—both in Thailand and around the world—have long believed.

The new insights, featured in a recent article by The New York Times and supported by emerging scientific literature, highlight that massage can make you feel noticeably better following strenuous physical activity. Its main benefit, however, appears to be more psychological than physiological. Despite the prevalence of massage stations at running events and the booming sales of massage guns from popular companies, robust scientific evidence supporting claims of accelerated muscle recovery or lactic acid ‘flushing’ is weak at best. As shared by a professor of exercise science at Australian Catholic University, “If you talk to athletes, massage is one of their favorite recovery strategies…because it feels good…[but] most of the purported physiological benefits of massage aren’t backed by strong evidence” (The New York Times).
