Tone and build your core with this Matrix Ultra Abdominal Crunch. The handles align to the shape of your body which creates a more comfortable motion throughout. The electronic rep counter and timer calculate the number of reps and the amount of time expended doing so. The back pads also sculpted to your back so as you bend the back pad doesn’t get in the way.
This machine’s elbow-pads create the downward force needed for the crunch.
