Hey /fit/ does muscle grow during the exercise period? or the rest period? I've been thinking about this for some days, what do you think /fit/?

when you exercise, you make tiny tears in your muscles, and when they're built back while you're resting, the body builds them up thicker... like callouses kind of. that's what makes your muscles grow

that's why you have to be careful not to over-exercise and to rest enough, or else you could damage the muscle with too many microscopic tears and injure yourself
