I have been trying to activate my glutes via clam shells and couch stretch.  As well as keeping glutes turned on through out a Glute Ham raise exercise.  Just really focusing on my brain holding the muscle through the movement.  I know for sure I can’t activate them when I am in a squat — Basically once I descend everything seems off — it almost seems impossible to have them activated through throughout the squat besides the top position. Would I be taking your info and applying it correctly?

Also, to take my left nav bone off the ground I am simply just taking it off the ground and arching my foot.  It seems like I haven’t been able to train this behavior without thinking about it.
