Ditto !!! I think you guys are mistakening rest pause for something else.
On the last set of a given bodypart when you reach failure you put the bar or dumbells DOWN (aka, rack the weight), rest for 10 - 20 seconds or whatever amount of seconds you choose, grab the bar or dumbell and do as many reps as you can. You repeat these mini sets about 3 times. You will not get many reps out, maybe 4, 3 or 2 and even 1. It adds a tremendous amount of intensity to the bodypart being worked. It is not for the faint of heart. Rest pause rocks.
