How to Use the Leg Extension MachineBuild Strong Legs
-- By Nicole Nichols, Fitness Instructor
In this exercise, movement will come from the knees.
Sit on the chair and place your feet behind the foot pads, which should make contact with your lower shin, just above your ankles. Adjust the seat so that the back of your legs lie flush with the seat and your back is fully supported by the seatback.
The quads are pretty strong muscles, but start with a low weight until you are comfortable lifting more. Aim for a weight that is challenging for you to complete one set of 8-12 reps.
Grasp the handles down at the sides of the chair, or place your hands on your lap. Try to keep your feet and ankles relaxed (do not flex your feet), with your toes pointing naturally forward. Pull your abs in tight to help prevent your back from arching.
Straighten your legs and lift the weight slowly as your exhale. Be sure that you don't lock out your knees. Hold this position for 1-2 counts. Inhale and slowly lower your legs back down—but not completely (the weight stack should not slam, but should come close to touching). Aim for 8-12 repetitions and 1-3 sets.
