I'm on the fence with this one: Hugo is one who I've admired for his dedication to natural BB'ing (and DON'T start that he's probably a liar crap with me) and his diet advice is great. Now here he's talking about 100 rep routines, but not forever. He then mentions dropping to 6 sets of 6 with more weight; on track there, and we all know you can keep dropping sets and reps and adding weight even further. The issue here is: is a 100-rep scheme going to work or do damage?
This from the M-time study on Max-stim:
<div></div><div id="QUOTEHEAD">QUOTE</div><div id="QUOTE">When lifting lighter loads that do not require full-force, the MNs (motor neurons) fire on a rotating basis. (X) amount of MUs are needed to produce (Y) amount of force. Since (X) is less than the sum total of all MUs, then some MUs are resting while others are firing. They alternate 'shifts' so that each MU has a chance to rest while others are firing. In this case since only partial recruitment is occuring, it takes longer for the muscle to fatigue and thus fatigue must be first induced in the muscle before full recruitment can occur.
So when lifting your 15 rm and going to failure, full-recruitment doesn't occur until the last few reps. The last few reps seem harder because some of the MUs have already fatigued (depleted energy reserves), so full recruitment is necessary to keep lifting. When failure occurs, enough MUs are fatigued to the point that force production is too small too overcome the resistance.
HIT training gets some full-recruitment, which is good, but at the expense of heavy fatigue, which is bad for muscle contraction and recovery.
Max-Stimulation training gets full-recruitment (or very close) on each and every rep for multiple reps.</div>
So I see that this system gets you to fatigue, and therefore employs all the motor units at the END of the sets, or the final sets, which you could have done way earlier with a heavier weight. - of course, that may not be so if you just finished a strength routine.
