Adjust the weight stack to the proper level by pulling the pin out of the stack and inserting it in the selected plate.
To adjust the seat backrest, either pull on the set to move it forward or press the seat lever “in” so the seat can be moved back. Once in position pull on the backrest to secure the stability of the seatback before sitting down.
The seat should be adjusted so the bend of the knee is near the end of the seat pad and the knee is aligned with the pivot point of the machine.
Place the legs on the top of the foot roll so they rest on the pad just above the ankle. Next, unlock the lap pad by pulling the red ball out on the end of the lap pad and then lower the lap pad to the top of the legs by rotating it forward and down. Release the red ball to lock in place.
To begin the exercise, hold the handles on the side of the seat and slowly flex the knees by drawing the heels back toward the buttocks for a full contraction of the hamstring muscles.
To complete the move, slowly release the contraction, returning the legs to the starting position.
Do not lock your joints in the straightened position, or allow the weights to slam down. You should keep a continuous resistance on the weights until the complete set is done.
The goal is to complete 15-25 repetitions in a 40-second time period.
