Designed specifically to maximize the Total Flex gym’s lower body effectiveness, the Performance Accessory Kit includes the sturdy Leg Extension attachment with dense foam pads for easy adjustability and comfort. The Leg Extension is great when standing for right and left leg kickback exercises that work your hamstrings and calves. It also works from a seated position for traditional leg extensions that target your front quadriceps. Three separate resistance cords come with the Leg Extension attachment for challenging varied resistance. Also included is a padded Head Rest for extra support and comfort. .
