I have recently programmed in some volume work on our efs belt squat machine. I was simply using the 5's pro, moving on to "50" reps on the belt squat machine and finishing up with "50" reps of weighted back extensions. I was doing this since I have come to realize that my much stronger low back stays fatigued from deadlifting and takes over during heavy squats....and turned to the belt squat to give the back a break. Not thinking anything about it, I felt less beat up and my wife actually asked me what I was doing differently because my legs looked much bigger all of the sudden.
My question is, in future programming, should I consider, or would you advocate, alternating between cycles of 50/75/100 "total reps" actually programming this in for hypertrophy? Or would you suggest sticking with the rule of "50"?
