Model: E7003A Leg Press Extension features an articulating foot pad that stays vertical to mimic a squat movement and allows for full extension during calf exercise. Ratcheting seat back allows for desired start position. Large, non-slip wear-resistant rubber foot pad allows user to easily perform both exercises. Users can easily engage the add-on weight with a simple push of a lever to increase the work load. This convenient design allows users to enter and exit on either side of the unit, a very beneficial feature when space is an issue. The large foot platform allows users of all sizes to adjust placement as needed, as well as have the space to move into different positions for exercise variety. The design of the foot pad assembly ensures that there is a smooth natural path of motion, much like that of a standing squat.
