I have been doing a 2 on, 1 off split and having good results! I think part of this is due to changing up my workout in general but also doing lower weight and higher reps. I am moving more into the 12-15 range for a while, rather than the 6-8 I was concentrating on. Every now and then I will dip into the 10-12 range if I am trying a new weight.
One thing about Robert's routine above and it would be cool if he commented.
........is that I am not a fan of hitting any muscles two days in a row! I don;t like that he shows chest and biceps on day one and then hits back on day two! I would think Chest and triceps may be better on day one and then back day two. Biceps could be put off till Thursday.
