Movement:
From the start position, draw your belly button inward toward your spine. With knees slightly flexed and aligned properly, slowly lower the legs. Stop if alignment is lost or when buttocks begin to “pop” off pad. To return to the start position, straighten the knees (without locking out) toward the machine. How far the knees extend (returning to start position) will depend on individual control capabilities. Full extension is permissible when controlled. Due to the direction of resistance, beware of hyperextension of the knee. Check knee alignment, stabilize spine and repeat under control. Always be in complete control of the resistance. You should be able to stop the resistance at any time during the exercise. If stopping is not possible, decrease the amount of resistance. Keep hips on pad.
Continually monitor alignment before and after every repetition.
