My rep and sets usually fluxuate and I will add in additional exercises when im on cycle. Which I am now. Also dependent upon my pump and how gassed the muscle is I will change reps and possibly add in an additional set. I will play with my grips also.
I am just looking for lean mass which comes with the diet anyhow, but I do not like a "bulky" look, more built and defined, which is why I keep my reps up a little higher. Im not a 4-6 rep, stupid heavy weights guy lol.
