Up until Monday I was on a split similar to the WBB routines. I've done this routine for about 2 months.
I switched to the following routine on Monday.
When I was doing R2 for back and bicep I was using weight very close to the ones in R1. However today when I did shoulders/tricep I could only lift significantly less weight than I was doing before. Roughly 30 pounds less on the shoulder press for example. Is using less wight going to hurt me, or is it fine since I've used the same muscles a few moments before in the preceeding exercises? I'm doing all chest, then all shoulder, then all tricep.
The second routine nails your triceps on the chest/shoulder/tricep split. If your tris are the weaker link in your chest and shoulder movemebts (which all use tricep for the lockout) then I can see how you may end up losing 30lbs.
The question is in which of the three exercises were you losing 30? if it was chest or shoulders you may want to think again of a different split (the first one looked ok to me but there are far more experienced members here who can help with splits)
...but if the 30lb loss was in tricep isolation exercises I really wouldnt be too worried. The tris are already getting nailed pretty good and i would expect to see a strength loss in them by the time you get to the isolation stuff simply becasue tris are the commom muscle in all the previous exercises. The tricep fibers are already getting plenty activated and the isolation is finishing them off really.
Thats my take anyhow.
