When i started the THT, I had the same thought. previously i was training extreamly hard but with very short rest periods. my body had got used to this type of training/rest period and the longer rest period of THT seemed too long. but once you get into THT and you do a 'ball busting' set of squats, bench press , deadlift or overhead press, believe me 3 min's will seem too short. don't forget you are supposed to be training to failure!! on each set. some of the sets ie. deadlift were 4-6 rep range, with the rest of the exercises in the 8-12 range. the 3 min's rest is to allow you to recover enough to do it all over again. also some of the smaller muscle group exercises are 2 min's ie. biceps, triceps, abs and some of the isolation exercises. the thing to really get right on this workout is to go to failure on each set and the rest period will take care of its self.
remember "no pain no gain!"
