My spine just ripped itself free from my body, tore right through my flesh, and ran away like the creature from alien leaving behind it a bloody trail, yelping like a puppy, after watching that video!
Not so sure my spine could handle the deceleration phase of that exercise, especially with that much weight.
BTW, welcome to the forums. Glad to have you here.
Can you tell us who some of your clients are? It's not every day we get trainers who've trained olympic athletes in here.
