Exercise is essential for a healthy heart and an active lifestyle, but experts warn that too much of it can sometimes do more harm than good. The key, they say, lies in balance and moderation.
According to Dr. Amiya Adyur, a leading cardiologist, while regular physical activity supports both cardiovascular and overall health, high-intensity workouts — such as marathons and triathlons — can strain the heart and cause irregular heartbeat or muscle fatigue in the cardiac walls.
She recommends at least two and a half hours of moderate exercise per week, including brisk walking, cycling, or swimming. Beyond this limit, the benefits plateau and may even turn counterproductive.
Research suggests that individuals who engage in over 75 minutes of intense daily exercise face a greater risk of calcium buildup in the arteries, which can lead to long-term cardiac complications.
Experts stress that the benefits of exercise have a threshold — beyond which overexertion offers no additional advantage. “The goal is to keep the heart fit, not to exhaust it,” Dr. Adyur noted.
They advise tailoring workouts to one’s age, physical condition, and lifestyle, and seeking medical advice before undertaking high-intensity routines — especially for those with heart or respiratory issues.
