This question is actually about your Bodybuilding PT article: What would be the effects of eliminating Structural Stage 2, and just alternating between Structural stage 1 and Stage 3 (Functional strength)?
A two-stage program would be easier and more convenient for my personal situation, but this is a theoretical and practical question.
With the high rep velocities employed in Stage 1, it would seem that hypertrophy would still largely be functional. And with the high intensity of Stage 3, relative strength levels should still increase over the duration of the program. Are 3 stages better in this case because they provide greater variety? Because they provide two whole weeks of recovery after the high-intensity work?
