No problem. I agree, its always good to mix it up. My rep ranges vary greatly on everything except for tricep work (which I usually keep at 15, sometimes 12 reps). Sometimes I go real heavy on biceps as they need to be torn up good for me to get any growth. But also Ive managed to get growth out of some dropsets I like to incorporate. One dropset Ive done,Ive gone up to 85 straight reps. I start off with 5 10lb plates on each side of the EZ curl bar on the preacher bench(can get reps with 180), thats 120lbs. Not heavy for me, but the max the bar will hold. I hit that too failure (15-20 reps). Then strip it down to 4 10's a side and rep that to failure. I continue the process with no rest until Im at 1 10lb plate a side and rep that a good amount of times,even though my arms are numb its never too heavy. But the burn is intense. Those 5 sets are one dropset. Ive repeated this 2-3 times in a single workout. As my endurance is good and I can nearly repeat the amount of reps on my second dropset. With a little rest. Then Id even hit a few sets on top of those. But Ive gotten growth with these lighter sets, due to the intensity of the sets I believe. Failure is key to me. Limbs ceasing to contract.
