The Greater Goods exercise ball is thoughtfully designed and intentionally made with premium material. Featuring an anti-burst safety mechanism and durable, non-slip finish that will help you achieve workouts, poses, and stretches time after time. Variety is the spice of life they say, so we designed three different sized balls (55 cm, 65 cm, and 75 cm) and created six different colorways, so you can channel your vibe into every workout. Included with purchase: exercise ball, inflation pump, bike pump attachment, two stoppers, one stopper remover, inflation band, and a free, professional home exercise video.
