I have not lifted for over a year and would like to start again. My goal again is to put some mass on and just get into shape. I have trained on a 4 day split in the past with one body part a week. My question is should I start again with one body part a week or something else. Reading all these magazines you see pro bodybuilders doing one body part a week, once you acheive your goal do you go with a one body part a week to maintain or can you start out with that? Some magazines say you can put mass on by doing two body parts a week:upper/lower twice a week. What should I start out with???
