This artistic board has a battalion of training options. The curve of the board varies with the anatomy of your grip and wrist pronation for an all-inclusive training regimen. Numerous "thumb catches" have been designed into the board to provide a full hand workout. The fine texture reduces skin tearing while forcing you to work on contact strength. Like all NICROS™ training products, an incredible amount of thought has gone into this training board. Please Note: Colors may vary but this board normally ships in solid blue.
