Thank you for viewing. Balance Board PRO. This equipment is for challenging balance training to strengthen your core and lower body. Just get on and enjoy! Your sense of balance will be honed, and your core will be strengthened. With challenging balance training, you can build muscle, improve joint mobility, and coordination. It's also ideal for training for snowboarding, skateboarding, and surfing. It has a safe structure that prevents the roller from popping out, and it's not as large as a balance ball, so it won't take up much storage space! Board length: 80cm, width: 21cm, height: approx. 11cm, weight: 3.6kg, made of wood and hard polyurethane. It was used indoors, but there are some minor scratches on the board surface. Please understand that this is a used item and consider purchasing it.
