Abstract

An apparatus including a pair of swingable arms with each having a leg engaging member. The arms are powered toward an open or aligned relationship to cause the leg engaging members to spread the user's legs to increase leg flexibility and the range of leg movement during the practice of martial arts. A threaded shaft journalled on a base of the device receives a wrench and moves a traveler sleeve and a pair of links acting on said arms. The leg engaging members are positionable along the arms for different sized users with the members having pads oppositely spaced from a knee joint to engage the upper leg and the lower leg. The leg engaging member are asymmetrically mounted on sleeves to permit varying the vertical distance of the leg engaging members above a floor surface to accommodate a wide range of adult and child users.
