Firm up that core!

The ProBody Pilates Mini Exercise Ball is made especially for core strength and balance, as well as for toning and sculpting with Pilates or yoga. It is made from a soft material free from common harmful harmful phthalates. This ball is burst resistant and has a better than money back guarentee. If it pops not only will they refund your money, they will also send you a new one! Because it is an anti-burst ball it has a plug instead of a valve that utilizes a straw device for filling up with air. Filling up the ball actually proved to be quite difficult and I was not impressed as far as that went. I was unable to get the ball completely filled with air, although it did not seem to effect the ball's performance. Once I get the hang of filling the ball with air I think I will like this ball a whole lot more. I like it as it is, it just has a learning curve to it :)
