Planks on an Exercise Ball

[OakLeaf]

I can just barely kneel - not that I've been practicing all that much lately.

But I'm still not sure of the progression you're describing, CC - do you bend your knees and keep your hips straight (similar to reclining Hero); or is it a backbend (similar to Camel)?



If you're not sitting on the ball with feet on the ground, then you don't have to worry about sizing the ball to protect your knees, and you can instead use size and inflation to adjust the difficulty. Larger ball is easier (because the contact patch with the floor is larger and the contact patch(es) with you are less angled); slightly underinflated ball is easier, for obvious reasons.

I've seen a guy stand on a ball and do squats. And it wouldn't surprise me a bit if the next thing V. posts is a video of her doing squats on the ball with a 50# bar.
