- Install One Handle and Spring Bar: Secure one handle. Insert a spring bar into the designated slot, ensuring it clicks into place. Select the desired resistance level by choosing the appropriate spring bar (blue for 40-80lbs, black for 60-110lbs).

Adjusting Resistance: The resistance level is determined by the length of the assembled unit and the type of spring bars used. Longer lengths provide less resistance, while shorter lengths provide greater resistance. You can achieve three weight grade settings:
- First Level: Make it longer on both sides (lower resistance).
- Second Level: Choose a long size on one side and a short size on the other (medium resistance).
- Third Level: Choose a short size on both sides (higher resistance).
