The Stamina Pilates Magic Circle is an excellent workout addition to anyone who does pilates or yoga. It is easy to use and the price @ Overstock.com is hard to beat. I was able to get it on sale and really am grateful that I was able to. I am sure it is much more expensive elsewhere. The Magic Circle is made of quality materials and appears quite sturdy. I have also found the Workout DVD very useful. I highly recommend this product.
