ok, I know what rep range I want to be in for each set, but I want to know is for each set you should either 1. Balance out at the weight you have or 2. Go for the max reps and change weight as you go 1 gives security and makes sure you don't fail a rep( read that working to failure is bad practice....) 2 would seem logical for better gains... also on pull-ups I can do 4 sets of 4-6 do I really need to add weight? also a side note does explosiveness in the exercise matter? Is it for more advanced lifters?
