I've never read it, so I can't comment.....but here is some bodybuilding truth if you want it.....progressively get good at squats, deadlifts, barbell rows, chins, bench presses, and military presses while eating more cals than you burn for growth.......then to drop added fat, cut cals below maintainence and continue to train heavy on the bread and butter lifts that built your physique, but with reduced overall volume/total workload.
