Stability Ball 65cm

JanePerkins

Hi I was getting a little bit bored of my normal excercise routine.. and I decide to try the ball! I tried a few excercises with the stability ball its 65cm.. you bounce and do crunches etc. I tried to log it into my excercise journal.. does anyone know how many calories it burns? do I count it as strength training or cardio.. hope theres an expert out there!!
