workout question
 

When working out how many days should you rest each muscle group before working them again? I have heard anywhere from 3 times a week to once a week.

48 hours it's alright normally you are fully recovered.

48-72 hours normally, depends a bit on how hard you
train that muscle group as well.

Check out this guy. He detailed his routine from chub to stud last year and he's keeping it up.
