The Unstable Balance Plank takes the unstable bridge concept and steps it up a notch to create tricky, unstable traversing obstacle. The plank 6in wide and 8ft long and is mounted to the crossbars using a sling/rope hardware.The plank is free to move as soon as the Ninja steps on it so it is important to keep all movements controlled. This is a great obstacle to work on balance, coordination and core strength.

**Crossbars must be purchased separately 

**Plank is made of a dense high quality wood
