how are we defining a good morning? i know louie, and by extension everyone at westside, use pretty much every variation of good mornings in the book (and a bunch that arent in any book), but if we’re talking about some of the 700lb good mornings ive seen some of the big boys doing off of chains on the youtubes then i dont really think its a good predictor of squat strength.
dont get me wrong, it teaches you how to fight the weight and beat the hell out of it when the bar drifts forward in the hole. personally i interchange good mornings and RDLs depending on whether i want more hamstring or back work, respectively. i like the stretch you get from hinging right down to just above parallel and then blasting back up. ive got up to 335 with this technique before, although that was one of the toughest reps of anything ive ever done. i just take a super wide stance (pretty much as wide as the rack) and i do them in oly shoes, both of which help to negate any eventual knee bend and keep the weight forward, forcing you to push the hips up and forward.
oops, didnt mean to derail the jump squat thread
