Why is exercise good for the body when you’re literally straining and destroying the body’s tissues every time you exercise?
In: Biology
Because your body responds to (minor) damage by healing stronger than it was before. Although this isn’t a conscious process, your body is basically going , “Well, *this* part obviously wasn’t strong enough because it got damaged. So I better make it stronger/more flexible/more durable/whatever for next time.” This is an evolutionary response to adapt us to be at strong/durable as we need to be to survive in our current environment without spending more energy than necessary.
Proper exercise is the art of straining your body enough to trigger the healing/strengthening process *without* doing so much damage that you permenantly lose capability.
Your tissues are constantly dying & being replaced…the mere fact that cells are being damaged/dying and healing/replacing is just part of being alive and isn’t inherently bad. Exercise is channeling that process so that we end up in better physical condition than we were.
