DynaDisc 4pk - Buy 3, get 1 FREE! (25% savings)
DynaDisc (13.5") is one of the best core training exercise tools available. It features many of the same benefits as a gym ball, but reduces the risk of falling. DynaDisc works your core muscles more completely than a gym ball because it focuses on those muscles no matter what position you are in. You can sit on it or use it on the floor, stand on it with 1 or 2 feet. Enhance weight training by standing on one or two DynaDiscs. Do sit-ups, lunges, deep knee bends, push-ups or leg lifts incorporating the DynaDisc balance cushion. Use it at home, then take it with you to the gym. Slip it into your suitcase when you travel so that you can have a core workout in the hotel room. It's perfect for seniors and chronic back sufferers to use as a chair cushion in therapy, at home-- even the office. Also a great cushion on bleachers at sporting events.
