I'm new to this forum, and although I've been going to the gym for a year and a half I've just realized that I'mdoing a lot wrong.
I keep readin how important it is to let a muscle rest for days after working it so that it can heal and grow. Is it bad if I play a sport that uses a muscle the day after I work it, or should I only not lift weights with it again. For example, yesterday I worked my biceps and triceps and I have a softball game today. Will throwing the ball/swinging the bat inhibit my muscle growth, or will it not matter as long as I dont lift a heavy weight?
