Designed to be used by standing on and leaning backwards on the inclined frame. Standing in this way means that the body is directly above the body’s centre of mass and then gravity and centrifugal force then holds the user in place. This means that the user is able to rotate or spin and staying in this position can the increase the speed of rotation. Leaning forward can slow the spin down and the user rotates, there are a pair of handle bars aids to hold on to as the unit spins. Leaning backwards is the ideal position keep going faster for longer.
