Alright guys i was wondering what your opinion is on a new work out i heard of. This huuuge guy at l.a fitness told me about this one. Basically it is 5 sets of 6 reps with constant weight but the trick is to only have a 15 second rest interval between sets. The workout is basically to do that for 5-7 different exercises on one muscle group. I've been doing it for a week so far and you get fatigued very quickly. Also it shortened my workout from an hour and 15 mins to about 35 mins. Let me know what you guys think. Thanx.
