To properly grow your muscles you don’t only need to strain them, you also need to have proper diet, good sleep schedule and most importantly rest. It’s why personal trainers suggest spacing out your workouts, never the same muscles in two consecutive days, to give them ample time to repair the damage and make them stronger.

Back hurt is typically caused by people sitting in a chair every day for too long. It doesn’t give time for the back muscles to rest and properly heal and grow.
