kBox
Leg Curl
The leg curl, or hamstring curl, does exactly what the name indicates: targets the hamstring muscle, calves and the glutes. The kBox makes this exercise even more functional since you are able to move freely and configure your own positioning.
Variations
With the kBox, there are three variations originating from the same movement pattern but are performed slightly different. First time doing the stand-alone leg curl, we suggest using support from either a wall or a rack.
Standing Leg Curl:
Performed using the ankle cuff.
Prone Leg Curl:
Performed using the ankle cuff, place yourself on a bench, set the range of motion and pull your heel to your glute. Make sure the kBox is fixed to the floor with the Floor Attachment.
Seated Leg Curl:
Performed using the ankle cuff, place yourself on a bench, set the range of motion and pull your heel to your glute. Make sure the kBox is fixed to the floor with the Floor Attachment.
