HA! Can you imagine if that ball would have popped when you were doing your crunches? That would not have been good.
I'm very blessed in that when I was OL focused, I trained with 2006 WSM Phil Pfister the last 10 weeks before each of his major contests the past few years. He would do two "gym workouts" a week, and I'd join him. Then he'd do his event work, while I did mine. The gym workouts were epic - heavy, unstable surface, and just down right silly. Nick Osbourne programmed it and some of the movements were insane. One of my favorites was a circuit we'd do - Conventional pull 585 for 5, sumo pull 225 on dyna dics x5, then stand on the ball side of a bosu ball and do RDL with 40lb dumbells. Absolutely insane. We'd do about four of those circuits. When were done we were done!!!!!And I loved it!All the best, Arden
