An ankle therapy device provides variable loading on targeted muscles and tendons, by utilizing a variable length moment arm to which the load is attached, and having the ability to change the angle of the load with respect to the orientation of the users foot. Thus, the device provides a variable resistance on the ankle muscles and tendons when the ankle is moved, and may target different muscles and tendons by changing the angle of the resistance. The device comprises a member to which the users foot is attached, and a rotatably attached weight support member to which a weight is secured. The position of the weight may be shifted along the length of the weight support member, and the amount of weight may be changed.
