i recently bought a stability ball and was just trying to use it on my own, which wasn't happening. i was trying to look at images from the net and copy them. i'm not that talented. & the video that came with my stability ball isn't really the best. grainy and short and moves way to fast. it reminded me of a bad '70's porn.
so, i went out and got "stability ball workout for dummies" with liz gillies. i've completed the workout five times now and i can REALLY feel it in my body. i'm exercising muscles i forgot i had. it's a 45 mintue workout but it really doesn't feel like it because you're doing 15 different exercises, plus warm up and cool down.
& just to let everyone know, I ACTUALLY SWEATED while doing this workout and it got my heart rate going. i can't recall the last time i actually sweated while working out. she's clear, she goes slow, she reminds you to breathe, they have variations for exercises (either easier or harder). i think it's a great place to start if you have a stability ball and don't quite know what to do with it.
