Taylor,back in the day,in the old Muscular Development magazines,then editor John Grimek used to say to do as many sets as it took to get the muscle pumped up and cogested with blood.
He said that once you reach this point,you should stop because anymore work would cause you to actually lose the pump and you would reach the point of diminishing returns.
Anyway,all bull shit aside,if it works, use it..........I would.
