In the chip procedure he describes the pivot through as trying to squeeze a towel with your butt cheeks for want of a better phrase.
Is this in a slightly more scientific way, contracting the glutes as the hips turn through?
I practice basic motion yesterday, then a chip shot with pivot into a tyre with a crate, without a crate and with a ball and the ball went a long wall with a 9 iron for such a small swing
Is this glutes feeling a good one to have (all jokes aside)
