Question

why do we feel exhausted after excercising

Answer 1

Exercise is supposed to make you feel energized — not exhausted. But if you're feeling lethargic after your workout, you're not alone. When you exercise, you burn calories and expend energy. Depending on the length and intensity of your workout, you may be physically taxing your body, requiring water, nutrients and rest to recover. Talk to your doctor before starting any new exercise program, particularly if you have health conditions or injuries.
