What happens to the body when you stop exercising? The body adapts to higher doses of testosterone, adrenaline, and endorphins when exercising regularly. Heart fitness decreases when doing light exercises in those who are accustomed to doing more intense exercises.
The rate of loss in muscle strength depends on age, diet, sleep quality, and your health condition. After 12 weeks, the amount of weight that we carry can significantly decrease, and the muscle fibers that are used can decrease as a result of lack of exercise.
