This firm heavy-duty ball is weight tested to 600 lbs. Made from a high density polymer that resists tearing and puncturing. It is also free from latex. Yoga balls are key to developing core strength. The round and mobile surface of the yoga ball forces the core muscles to work harder to maintain balance; allowing you to work more muscle groups.
