When More Isn't Working

 The problem with Negative Accentuated or the slow-lowering of the weight is that it's not natural movement -- and most people experience it that way, and so discontinue that method of training. Undoubtedly what it does do is make the body prematurely fail -- but that failure is not caused by pure muscle failure -- but by cardiovascular failure -- and that is seen in all the videos claiming to be high-intensity training -- by everyone, including Arthur Jones. That was also the problem with Isometric training -- causing the vasalva effect -- as well as when lifters pass out from heavy deadlifts or squats.

That is the natural and predictable result of not breathing when one artificially resists the natural work of gravity -- in lowering the weight. That's why the human body will sense that it is the wrong thing to do -- because the intelligent thing to do, is allow gravity to perform that work whenever possible -- while positioning oneself in each rep -- by getting into the relaxed position as much as possible -- preparatory to the next positive movement. The relaxation is just as critical as the contraction -- but if one is contracting as hard or even harder in the relaxation phase of a movement -- then there is no alternating relaxation/contraction cycle -- that not only performs work, but enables the optimal respiration and circulation (flow) that enables functioning and development.

Most of the bodybuilders who got into it around the '50-'60s were told by Bob Hoffman of Strength and Health, and Perry Rader of Iron Man, to begin their workouts with light squats alternated by light pullovers -- and most made unexpectedly fantastic gains doing so. What they did right was time their movement to the natural rhythm of their breath -- exhaling to lift the weight, and inhaling as they lowered the weight. But if one resists the lowering of the weight, one invariably has to stop breathing (inhaling) -- which is the natural result of relaxation and the expansion of the chest cavity.

The distinguishing feature of "high-intensity training" is the elimination of rest between one set of each exercise -- and the easiest way to achieve that is to do one set of 50 repetitions with a weight allowing one to do so -- with no rest between exercises. In this manner, one can achieve muscle failure without the cardiovascular failure -- as each muscle pre-exhausts the next, and achieves complete exhaustion in about an hour. That usually requires one week to fully recover -- accounting for the infrequency requirement. The trick then is recovering from extreme muscular soreness -- which can best be alleviated by doing those movements with no weight at all -- but rotating (contracting) at the head, hands and feet which are the insertions at the most distal parts of the body to effect a flow to remove the inflammation, while producing the void to allow new nutrients into those tissues.

This is particularly helpful for older bodybuilders who no longer experience growth and may even be experiencing decline (sarcopenia) despite their efforts. They have to upgrade their understanding of the process -- because more of what isn't working, is not the answer.
