Thanks to everyone who replied. I appreciate the input.
I have one total body ring workout and tried it once with my son's kick ball and it worked ok. The other day I did a pilates on the ball workout and really, I mean really, felt it the next day and it got me to thinking, hey, maybe the pilates ring would be as effective a tool as the ball. So, hence my question. I think the video I have is Living Arts something or other.
Thanks again...
