ever since i saw on youtube that old fucker with the reporter doing 1000lbs for reps with the piss ant legs doing quarter reps i just laugh when i hear anyone mention the leg press. honestly, after seeing that i don't care if you use 5000lbs on the leg press. i'm sure whoever you are, you've found a way to make the movement as easy as possible. leg press is just a show pony exercise to me.
leg training for me is squats. there's never been a choice really. i have to have functional strength and power and legs, hips and trunk are the priority. upper body with no legs would be like strong branches with a week trunk, ready to collapse from the first decent hit.
