This egg-shaped ball rolls back and forth in only one direction providing more stability than the traditional round ball. This makes it ideal for pregnant women, beginners, and seniors.
When your focus is on stretching, this egg ball makes a great tool to have when you want more stability than a round ball gives you. Releasing your muscles to the stretch comes easier with the added degree of stability.
Use it as a desk chair or when you are watching television for some added core training.
