An extraordinary sport and training device for balance training as well as for the stabilization of the whole core musculature. The IndoBoard is a balance trainer and consists of a specically formed board and a high tech synthetic roll. An extraordinary training device for all sport disciplines which require agility and balance coordination. The IndoBoard improves coordinative capabilities as well as balance. It strengthens the legs, improves the flexibility, and stabilizes the core musculature. The board is ideal for surfers, wakeboarders, snowboarders, skiers, ice-skaters, gymnasts, and many more. The IndoFlo Pad is here the perfect complement. Unlike when training with the roll, here the board cannot slip away so easily.
