How to set it up

1
Adjust the seat and restraints so the machine pivot matches the torso movement.
2
Place the feet securely and hold the handles or pads as designed.
3
Choose a load that allows a small controlled spinal curl.

How the movement works

1
Curl the ribs toward the pelvis while the machine arms and pads travel together.
2
Return to an upright supported position without letting the weight pull the spine backward.
