Thanks. That means a lot from a pro!
Yes, I can do the resting the calves on the roller thing but I can't support my body on my hands and move back and forth. My wrists hate it.
I've tried with different balls but they keep pinging out and rolling away! I'll try again. No lax ball here but there is a golf ball and a tennis ball.
Do you find you have to keep your floor really clean? The first night I did it I got a splinter in my wrist (the best space is in front of the wood burner). It's a dangerous business, keeping fit.
