More exercise isn’t always healthy: CMC Vellore doctor explains how much running, walking, strength training is safe
While regular exercise is widely praised for improving fitness and reducing lifestyle-related health risks, medical experts warn that too much physical activity can harm the body instead of helping it. According to a senior doctor from CMC Vellore, the balance between moderate activity and overtraining is crucial for long-term health. Activities like walking, jogging, and strength training deliver significant benefits when done in safe limits, but excessive workouts can cause muscle strain, joint injuries, hormonal imbalances, and even cardiovascular stress. The expert emphasizes that adults should aim for a mix of aerobic and strength-building exercises spread throughout the week, rather than pushing beyond their body’s natural capacity. Walking briskly for about 30 minutes a day, combining it with moderate running or light resistance training, is generally considered safe. The key lies in consistency, rest, and understanding one’s fitness level to prevent exercise from becoming harmful.
