Squatting and foot placement.

[600@50]

The most advantageous stance for strength/power squat will be based on the length of your back, the length of your legs and the ratio between the two.

From Dave Tate's squat manual:

If you have shoulder issues, choose a medium to wide grip.
If you have a short back, choose a medium to wide stance.
If you have a long torso, choose a medium stance (the longer the torso, the closer the stance).
If you have long legs and a long back, choose a close to medium stance.
If you have long legs and a short back, congratulations. You can squat any way you want.
If you're using gear, obviously a wider stance is best as the gear supports the hips.

Also, depends on "Your Range of Motion"

If your Back is Perfect and you have short Legs, you can squat down to your heals, (although this is tough on the knees and shouldn't do it, imo). You Range of motion is largely determined by your Pelvic Floor Muscles.
