Great fitness ball and excellent instructional DVD. The ball is very puncture resistant - and I have cats that test it almost every day. I would like to see a longer workout by the same instructor for this product. The fitness ball can also be used with pilates and strength training. It supports the back and strengthens the core muscles.
I BOUGHT THIS BALL [...]AND IT WORKS GREAT. YOU REALLY FEEL THE RESISTANCE IN THE CORE MUSCLES. IT'S REALLY GOOD FOR THOSE QUICK BOUTS OF EXERCISE. IT'S A GREAT INEXPENSIVE EXERCISE EQUIPMENT
