As a coach I think you should always be asking yourself if you like the way the any movement looks and I typically don’t love the way the squat movement looks. One of our most important jobs is to improve movement efficiency and with the heels elevated I almost find that the movement immediately looks better, for two big reasons;
1️⃣ the biggest reason, the heel elevation essentially gives the athlete more ankle mobility
2️⃣ elevating the heels gives the athlete an anterior weight shift that allows them to ‘sit back’ in the movement.
Beyond this, it’s important to be in tune and understand the group you are coaching. We know many athletes (or anyone) will typically present ankle mobility – so while we are also working on improving ankle mobility, why would we try to jam a square peg into a round hole.
