So you are saying doing 1 set to failure is all i need to stimulate growth? LOL come on... I can do a set to absolute failure where I literally can not move the weight another inch... rest about a minute and then am able to do more reps with the same weight. You say the rest of these reps and sets "won't help", not buyin' it.
And I do not agree with you at all that doing a set to failure has "overcome the body's previous musclar ability... and that is reason enough to respond and improve etc"... even if last week i did a set of flat benchpress for 5 reps and this week i was able to do 6.
Look, I'm not going to argue with you. I trained the way you speak of for 2 years and LITERALLY didn't put on a pound. You don't have to believe that, but I have no reason to lie to you. I had that mentality, where I had some level of fear and uncertainty that I "wasn't doing enough to stimulate growth". I kept it up regardless of no progress. I switched to my current fashion of training...well I used to be 128 lbs. I'm a lean 198 lbs after 3 years of this type of training and EVERY other person I have trained with using this method have had very similar gains.
