For as long as I have been lifting weights, I have adopted the method described by John Berardi in his article, "The Creation of a T-Man":
"...I try not to mess around with the weights too much. I pick a weight that I'd fail at after about ten to twelve reps and bang out four sets of as many as I can do. If I can complete all the reps for four sets, I up the weight during the following session. If I can't complete all the sets with ten to twelve reps, I stay put until I can."
I train in exactly the same manner as Dr Berardi has summarised above, except in some sessions I "bang out" four sets of six to eight reps and in others, four sets of ten to twelve reps. However, recently, a friend has informed me that this method of training is futile and that the only option that will yield significant results is to increase the load each set and obviously, if necessary, decrease the number of reps each set. What do you folks think? I certainly hope I haven't been wasting my time in the gym!
