there’s really no lockout phase. You just kinda stand up and lumber yer way back to the rack and dump the weight. I’ve been squats for months now and I think it seriously neglects the VMO. The outside of my thighs are alot bigger than the inside. I think squats should be mixxed with some leg press partial lockouts or leg extension partial lockouts to keep balance. Also… the hypers/back extensions that u need to compensate for similar reasons… u dont really lock out and straighten up when yer squatting so yer lower back can get weak relative to yer legs.
Deadlifts have lockout and military press… and bench press… The final lockout usually exercises some useful small muscles i think that squats dont really hit. If you fully locked out a squat, it would but u’d be in an awkward position with tons of weight on your back.
I think people on here dis the ‘machines’ too much and its not doing anyone any favors.
