Abstract
Abstract To support the feet of a user during ninety-degree bent-knee situps, a semi rigid panel is secured to a wall above the floor and a pair of juxtaposed Velcro hook-type patches are secured to the face of the panel. Conventional elastic foot-ankle supports or anklets are put on the feet but reversed with longer portions on the feet and a pair of Velcro loop-type patches are secured to the soles of the anklets to detachably engage with the patches on the wall.
