Quote from ROCK SOLID:
when i am in the gym, i am the hardest working guy there! i am no half ass lifter!
i do every set to failure. yes, i get the burn on every set, too. obviously i will if i'm lifting til i can't do a complete rep on every set.
i don't think we really disagree.
my point is just that, to really get the MOST burn feeling possible, it will come from doing a lot of reps or a lot of sets.
i guarantee you, if next time you go to the gym, you will get more of a burn feeling if you do 4 sets of whatever without resting than you would from doing 2 sets, resting between sets. (both will damage the fibers.. lactic acid build up (burn) is not required to build muscle). but yes, i feel the burn on every set, too.
think about it, if the burning feeling is caused by lactic acid build up, the more you're working the muscle, the more will be building up. but yes, you can still get a burn without high reps/sets.
