Abstract: An exercise machine that can simulate the act of paddling a kayak with a spinning flywheel to provide exercise resistance and also produce a gyroscopic force to rock the exercise platform for a realistic effect. The flywheel is mounting on a shaft with moving supports that allow the flywheel and shaft to articulate in one plane only.

In this plane the forces are transmitted to the exercise platform and cause a rocking reaction due to the gyroscopic force of the spinning flywheel.

Abstract: An exercise and physical therapy device using inertia and momentum to provide both resistance training and passive assisted movement for a user's foot or feet. A foot pedal is mounted for pivoting movement in a frame. The pivoting movement of the foot pedal is translated into rotational movement of a flywheel. As a user begins pivoting motion of the foot pedal, the flywheel provide resistance to this movement. The user may continue to use the foot pedal for resistance training. Once the flywheel is in motion a user may rest a foot or feet on the foot pedal and the rotational movement of the flywheel caused by the flywheel's momentum will cause pivoting motion of the foot frame. This presents passive assisted movement to a user's foot and legs until the momentum of the flywheel is dissipated.
