Abstract: An exercise machine includes a base frame with a seat adjustably connected thereto for longitudinal movement towards and away from a foot support on the base frame. A bent arm is pivotally mounted on the base frame adjacent the foot support, and has a pair of cushions adjustably mounted on the arm, so as to pivot through an arc with respect to the foot supports. Weights may be added to the bent arm so as to further bias the cushions against pivotal movement. A person seated on the machine exercises the tibialis anterior muscle by pivoting the cushions with the toes of the foot with respect to the foot support.
