Wouldnt I be better off doing 6 sets til failure on squats, then just doning 3 sets til failure on squats and 3 sets til failure on leg press. Either way it is 6 sets of failure on quads. Wouldnt it make more sense to stick to squats for all 6 failure sets? Same goes for Back, wouldnt I be better off doing 6 sets of failure on barbell row in stead of 3 on barbell row, and 3 on cable row? Im really confused on sets til failure. Is it ok that each set I would have to drop the weight to make my reps again on the next set? Because after doing my first set of 12 on squats with 225 of failure, there is no way I could make 12 on my next set at the same weight. I would have to strip like 10 to 20 lbs off each subsequent set. Is this ok? Some say only one set til failure per excersise? Why stop there? I think Im bout to stop working out, because its to confusing. LOL
