I am on a winny, fina cycle and am trying to do about 8 reps per set and going to exhaustion on each set so I make sure that I am breaking down my muscles in about 3 sets. Problem is that after I do 8 reps for the first set at a certain amount of weight, I can only do about 6 reps at that same weight the other two sets. Is there anything wrong with this? Thanks for the info.
