Right now I'm on a 4 day upper/lower split. Monday: Upper Tuesday: Lower Wednesday: Rest Thursday: Upper Friday: Lower Saturday: Rest Sunday: Rest However, I feel like I get worn out and I have too much to do on my upper body days, so I was thinking about splitting my upper body workouts up. Monday: Chest/Tris Tuesday: Lower body Wednesday: Back/Bis Thursday: Rest Friday: Chest/Tris Saturday: Lower body Sunday: Back/Bis Thoughts? Should I stay with what I'm doing or switch to the 6 day split? I get plenty of sleep if that is a concern with recovery time.
