Nail on the head right there. ^
Dave just likes DC training because he gets excited by the fast increases in strength he gets from it. Not realizing that strength increase alone on one rest-pause set is no substitute for volume, atleast not a permanent one. Sure he's grown, but put anyone on enough Test, Deca, and Dbol and you'll grow on just about any stinkin' routine.
oh yea, and all those tiny powerlifters too....all that low volume , 3X3 stuff, what are they thinking?
have ya actually tried the program?
