Why is exercise good for the body when you’re literally straining and destroying the body’s tissues every time you exercise?
In: Biology
There’s a difference between the muscle damage that occurs during normal exercise vs the muscle damage you’d get from trying to catch a 200-pound weight that someone threw to you.
Normal exercise creates microtears that easily heal, and in the process they stimulate new growth in that area. That makes the muscle bigger and stronger over time.
Total destruction (like large tears in the muscle) is different, and can take some time to heal before you can use that muscle again.
