One of the draw backs of going to failure in every workout, besides limiting muscle recovery time (CNS), is much more stress on the joints themselves. One of the reasons that PL'ers approach the point of failure only a few times a month. The point is to check their progress only. Funny thing is is that Pumpster is always so concerned with the stress and danger on the joints. Yet he encourages going to failure.
If Pumpster can provide the envelope that Dillet and Wheeler did not push, I wish he would send it out to everyone. Seeing as how Dillon and Wheeler only did "pussy" waste of time workouts and were not that much concerned with hitting failure. Seems Pumpster knows best and could have made those two guys even greater. Interesting to see if Pumpster could go through a complete workout doing their "pussy" stuff. Or match a pair of 20"-21" guns.
Arnold and Oliva (worked 1 or 2 sets at the most when with Jones, a short period,..going to failure was the point but just for those 1 or 2 sets) are always Pumpsters main examples. All time greats, to be sure, but that was 40 years ago. Some new slants on serious training have developed since than to help BB'ers to reach their own potential. Can combine some of the old training ideas with the current stuff of course .Pumpster may want to step outside the box and broaden his thinking towards modern BB'ing. Or have a more open mind when it comes to training and advancement. Good Luck.
