Foam rollers are used to improve balance, whether for general fitness or rehab sports performance. The durable, high-density Stott Pilates® EVA Foam Roller is soft to the touch and has excellent memory characteristics, meaning it will regain its original shape after being compressed. The full foam roller offers a significant challenge when used for balance training, and the rounded corners add to the comfort level.
My personal pilates trainer had me use this roller and it felt so good on my back that I just had to have one of my own. It's great for your posture. I love it.
