There’s a big difference between “stressing” a muscle and something non-muscle.
A muscle gets stressed and the body says “I need more muscle here” if it happens enough.
Your ligaments, bones and such just get damaged. The cartilage in your knee can’t be repaired. The disc in your back is more like a bag, over stress it and it deforms permanently
