yeah, the last week I have had it kind of like...

Day 1- Back and Chest
Day 2- Arms and Abs
Day 3- Legs
Day 4- Shoulders and Abs

I am trying to gain and I have a hard time with it as it is, and I have a decently active life so I don't do cardio a lot anymore. I do it usually when I feel like I have a lot of energy.
