Bionic Fitness introduces the AbStar Air, a versatile, simple-to-use alternative to the unwieldy exercise ball. The rounded-star design offers the benefits of an unstable surface for exercises involving the muscles of the lower extremities, abdominals, and whole body. The product is only nine inches high, which helps to make it safer than larger products and also easy to store. Users can do seated, standing, or reclining exercises, using a space equivalent to that of a yoga mat. The unit is priced at $39.95, with free shipping in the US. Customers also receive access to free online exercise videos with their order.
