The Blue Maxafe Fitness ball. Made by Ledragomma in Italy, the Maxafe Balls combine the quality of the Original "pezzi" Gymnastik and Physioballs with burst-resistant technology. These durable balls are very effective for resistance, flexibility, and interval training. They are safe, comfortable, and affordable. The Maxafe balls are appropriate for almost all fitness levels. They can also be used as effective tools for seniors and physical rehabilitation. The Maxafe ball is heavier vinyl with a texture that feels softer and less slick. If the ball is punctured, the air will slowly seep out without bursting and without dropping the exerciser to the floor. Available in sizes 42, 53, 65, or 75 cm.
