I tried them a couple of times in PUB and in the "Tough core" premix in Core Max and spent more times trying to not to fall on my face than doing the actual exercise!!! Does anyone else have trouble with that one? And do some of you have tricks on #1 how to stay on the ball :7 and #2 how to do that exercise with proper form?
Thanks
