The Discovery™ Series Plate Loaded Leg Extension features independent arm movement to allow for greater balance and muscle engagement. It is easy to enter, with a single spring-assisted back pad that adjusts easily from the seated position. The lower starting weight and balanced strength curve further help to provide natural resistance through the full range of motion. Easy back pad adjustments allow for quick modifications to ensure proper position during exercise movement arms allow for users to improve muscle balance through the focused engagement of each leg, minimizing compensation of weaker muscles. The counterbalance provides a smooth and fluid feel throughout the range of motion.
