Made of High-Quality PVC Material You know what they say: the best way to get fit is to jump on a trampoline and bounce around. But if you don't have the room for one of those, or if you're a bit late getting home from work, then we've got you covered with our Physiostore TheraFit PVC Mini Air Filled Gym Pilates Toning Ball. It's small enough to hang on your doorframe, but big enough to give you a full-body workout. And it's made of high-quality PVC material that won't damage your walls or floors when it's inflated! It's also made with an inflatable tube for inflating and deflating the ball with ease. Just open up the valve and let the air come in! And once the ball is fully inflated, use the valve again to let out as much air as required for your workout routine. This indoor/outdoor ball is ideal for use at home, in the office or in the gym—you can use it to improve balance, co-ordination, flexibility and circulation while strengthening and toning your overall body muscle. With an inflating tube and valve included, it's easy to inflate and deflate this ball so that you can make sure it's ready to go whenever you need it!
