HD-3400 Leg Extension/Leg Curl

Leg Extension Exercise Adjustments

To perform the Leg Extension exercise, first adjust the back pad by releasing the pull pin. Position it so that when seated with your back flat against the back pad, your knee joint is aligned with the pivot point of the exercise arm (the backs of your knees should be contacting the front edge of the seat pad). While seated in the machine, located to your right is the ROM(Range Of Motion) Adjustment for the exercise arm. Set the exercise arm by releasing the pull pin and positioning it in one of the lower slots labeled Leg Extension Adjustments. The adjustments are numbered from 1 – 8 with 8 being the farthest the arm can be positioned for maximum travel.

Take your seat on the machine in an upright position with the lower pad resting on top of your ankles. Re-adjust the ROM for less range if there is too much strain on your knees. You may then adjust the thigh-stabilizing pad by releasing the pull pin and rotating the pad down to rest firmly on top of the thighs. Test the weight. If exercising proves to difficult, adjust the exercise arm position for less travel or lighten the weight load.

Select the desired weight. While grasping the handles push upwards against the ankle pad arcing upward while exhaling until your legs are at full extension taking care not to lock your knees. Hold for a moment, then while inhaling, slowly return to the start position to complete a rep. Repeat this movement for the desired number of reps.
