Can someone explain the difference (if any) between a full set and a split set. For instance, say I’m doing barbell curls, and I want to get 8 reps…what’s the mechanical/phyisiological/muscular/etc difference between doing all 8 reps, or hitting failure at say 6 reps, resting for a short period (10 seconds, maybe dropping the weight), and then banging out two more reps?
