good mornings are a fantastic exercise often used by performance athletes and powerlifters to bring up their squats and deads.
deadlifts (done correctly) are great and probably the best exercise you can do (past squatting) for both putting on mass and burning fat. it's not difficult (at all) to do stiff-leg properly, assuming sufficient mobility.
leg press has always been regarded as a great tool for bodybuilders to build leg mass. no, it's nowhere near as awesome as a squat, but it builds lots of mass due to isolating the prime movers and is a suitable option for those with back issues, provided the RFESS isn't doable.
also - i've always thought of as leg extensions being a great quad exercise for body building.
i could be wrong, though. i've always been focused on performance training/powerlifting.
i agree that the rest are trash.
