Look Ma, no hands...I wish...

I don't know about progressing from bird-dogs on the ball, though. I think it's a lot easier to kneel than to do a bird-dog. JME.

I was thinking something similar this morning - I haven't done ball exercises for a while so, I do remember thinking one arm or leg at a time is easier than kneeling, but opposite arm and leg... That was the order on my exercise sheet though.
