Setup and Assembly
The SURFOU Resistance Bands Set requires minimal assembly. The bands are ready for use directly out of the storage bag.
Attaching Handles:
To use the handles, simply loop the desired resistance band through the metal ring on each handle. Ensure the band is securely threaded before beginning any exercise.
Using the Door Anchor:
- Open a sturdy door.
- Place the foam anchor end of the door anchor on the side of the door that closes towards you, at the desired height (top, middle, or bottom).
- Close the door firmly, ensuring the anchor is securely trapped. The loop end should be on the opposite side of the door.
- Thread your resistance band through the loop of the door anchor.
- Always pull the band away from the door's hinge side to prevent the door from opening during exercise.

Maintenance
To ensure the longevity and performance of your SURFOU Resistance Bands, follow these maintenance guidelines:
- Cleaning: Wipe the bands with a damp cloth after use to remove sweat and dirt. Avoid harsh chemicals or abrasive cleaners.
- Drying: Allow bands to air dry completely before storing. Do not expose them to direct sunlight for extended periods.
- Storage: Store the bands in the provided carrying bag in a cool, dry place away from direct sunlight and extreme temperatures. Avoid storing them near sharp objects or rough surfaces that could cause damage.
- Inspection: Before each use, inspect the bands for any signs of wear, tears, or damage. Discontinue use immediately if any damage is observed to prevent injury.
- Material: The bands are made from high-quality TPE, which is durable and non-sticky. Avoid stretching them beyond their intended limits.

Troubleshooting
Resistance bands are generally simple to use and maintain. If you encounter any issues, consider the following:
- Band Snapping/Tearing: This is often due to excessive stretching, nicks from sharp objects, or prolonged exposure to harsh conditions. Always inspect bands before use. If a band shows signs of damage, replace it.
- Loss of Elasticity: Over time, with heavy use, bands may slightly lose elasticity. Proper storage and avoiding overstretching can prolong their lifespan.
- Discomfort with Handles: Ensure handles are properly attached and your grip is firm. If discomfort persists, adjust your grip or consider using gloves.
