I am not understanding the concept that doing 15 reps is good for cutting. I know it's not good for building muscle but how is it actually good for cutting?? Is it the fact that you are burning more calories and blood flow is increased in the areas that you are working. Say for chest workouts you are doing 15 reps, more blood flow is drawn to your chest therefore it's easier to burn fat in that area?? Would that be the reason why it is said that higher reps is good for cutting??
