lol at the backlash against zappo!! lmfao!
karma… gets us all in the end… some sooner than others.!
OP, I love squats, i cannot perform full atg free bar… so i do power sq. and atg smith, then atg front.
I have done leg presses and got upto a fine ol’ weight on it of 8 plates a side (25’s of course) with decent form - full rom with 7, so lets stick with 7. I got some good growth, but my leg/knees woild shake under all the weight bearing down onto the joint (soft knee but still)… i mean thats like 400kgs just counting the plates. I was about 73kgs at the time - my body wasnt built to hold that much, not even as a heavy support (between reps).
As for squat, you can lift what you can lift. what your progression and body can handle. I can now do 3 plates a side on that, and it is good, in proportion to my body, size and overall strength. I go 1" below parallel. Then the other squat exercises i mentioned.
Overall, i prefer squats, they have given me some much improvement on my legs, which are almost upto par with the upper half, something not many of us can say.
I believe executed safely they both have their advantages and dis, but i would go with the squat first choice anytime, until i think my own physical condition dictates whether i should have a large load on my neck or not!
I think with balanced programming, good health and joint mobility, squats executed well are safe and very very effective, at building the WHOLE upper leg in its variations.
The leg press is just its cheaper cousin, that people either choose due to injury, weakeness of the mind, as an anillary exercise or as a rotational replacement.
As will all exercises it has its place and is high in the food chain, but not as high as a free barbell back squat.
