Forever Flex Exercise Ball I was very lucky to try this amazing product. I’ve always hear about how great the exercise balls are, but it didn’t give me the motivation to buy one. Now that I’ve tried it, I wish I had bought one sooner. The benefits are endless and my main concern is my back. I spend a lot of time sitting down and my posture is awful, but if you are using the ball as a chair, you have to stabilize it by sitting aligned and straight. It also helps to stretch your back. I found amazing exercise routines in the live infinitely website: www.liveinfinitely.com One thing I love is that is not generic, they are different sizes depending on your height so you can get the perfect 90 degree angle while sitting on it. The forever flex yoga ball is made of high quality material and can support 2,200 pounds. It comes with a hand pump, air plug remover and an additional air plug. http://www.amazon.com/dp/B0157JGD0E/ref=twister_B010J1JTCY?_encodin...
