I know some people in my weight room that sometimes do a negative workout or somethin like that. Anyways what they do is put quite a few 5 pounders on a bench press or curl bar or whatever they want really and do repititions until they cant do it or try to do the same amount of repititions each set. The catch is is that they can set it down to rest. After each set a spotter will take a 5 off of each side. This gets pretty tiring and totally kills you when you finish the whole workout lol. what do u guys think of this?
