4. Setup

The MERACH Twister Arm Trainer features a detachable design for easy assembly and storage. Follow these steps to set up your trainer:

1. Take out the two U-handles and the central spring bar from the packaging.
2. Align the ends of the U-handles with the connection points on the central spring bar.
3. Press the small silver buttons on the spring bar and insert the U-handles until they click securely into place. Ensure both sides are firmly connected.
4. To adjust the resistance level, locate the adjustment holes on the spring bar. There are multiple holes for varying resistance.
