About this machine
Pulling machines train the back on a defined path and make it easier to learn shoulder-blade control without swinging the torso. Vertical pulling is closer to a pull-up, while horizontal pulling is closer to rowing; learning both gives a more balanced programme.
Muscles worked
- Main load: Chest.
- Stabilization: trunk muscles help hold position.
- Should not hurt: joints or lower back. If they do, reduce load and check setup.
How to set up
- For the Pure Kraft Butterfly Reverse Dual, first check its source-listed detail: uses moving or rotating handles.
- Set the seat so the handles line up around mid-chest.
- Keep the shoulder blades against the support and plant the feet.
- Choose a start position that does not overstretch the shoulders.
- Check that both sides start symmetrically.
