30 Days of Squat! (Day 13) - "Drive through the heels!" Cue

Many years ago, I had an online "interaction" with a trainer of some prominence who said that the cue to "drive through the heels" while squatting was stupid because the weight should be evenly distributed throughout the foot. Yes, it is true that the weight should be evenly distributed, however the reason for the cue to "drive through the heels" is to discourage the common error to shift the weight to ball of the foot, and to engage the hips and hamstrings more, NOT to literally (and potentially  dangerously) shift the weight backward on the heels.

It's interesting because Dr. Stuart McGill mentions the heel drive in this interview: Dr. Stuart McGill Interview while discussing the bird-dog pose at about 45 minutes into the interview.

VS.

The subtle differences can make a big difference.
