For the last time, and this is the last time I mentioned that I have squatted using different types of equipment. I shuffle my squatting motions around as I like change. The squatting motions that I do are the king squat (shown), smith machine squat, barbell squat, I also include leg presses on the 45 degree angle and the inverted leg press.
Each movement is done either very deep or above parallel, it really depends on what I'm aiming for. I have never been a pure bodybuilder, I consider myself more of a power/strength athlete personally.
That lift wasn't done all the way down, but it definitely helped increase leg size and overall explosive power.
I have been training for 18 years, over that time I have
I have rock bottom barbell squatted 500lbs for 5 reps with a pause at the bottom
Smith machine rock bottom (with spot) 700+ for 4 reps
Smith machine slightly above parallel around 1000lbs for 4 reps (16 plates on the bar, 2 plates added to the middle of the bar or on a dipping belt, and a person standing on the stack).
Barbell squat above parallel 855lbs x 4, 675 x 20 above parallel.
Stifflegged deadlift 535 x 8 reps
All done at a body weight of 205-220lbs.
Except it and move on...
