Exercise is described as medicine for the heart, and for good reason. Regular physical activity can lower blood pressure, improve fitness and reduce the risk of heart disease and stroke. But there is a point where the question changes from “How much exercise is good?” to “Is the body getting enough time to recover?”
That distinction matters, especially as intense workouts, marathon training, long-distance cycling, high-intensity gym sessions and fitness challenges become increasingly popular. The pressure to run farther, lift heavier or train every day can make exhaustion look like progress.
The heart normally responds to exercise by beating faster and pumping more blood. That is a healthy adaptation. The concern is not that exercise itself is harmful. It is what can happen when very demanding exercise becomes a repeated physiological stress, particularly when recovery, hydration, nutrition and sleep do not keep pace.
“Exercise increases the workload on the heart, but this is a healthy, normal physiologic response. It’s not the length of an exercise, but what happens to the cardiovascular system when it is subjected to extreme physiological stress on a regular basis,” said Dr Devika G, Cardiologist at HOSMAT Hospital.
So, where does healthy training end and excessive training begin?
