I lift about 5 times a week with each day focusing on one body part, ie chest, legs, arms, shoulders and back. This is the style most weight lifters have told me to use to maximize rest. But how do u combat muscle overlap. For example when you do back you are working your biceps as well. Most chest workouts hit your triceps, a lot of shoulder excercises work your chest and back. So aside from doing legs, most body parts are going to be worked multiple times. How do you ensure they are getting the proper rest?
