6. Maintenance
Proper care will extend the lifespan of your SURFOU Resistance Bands:
- Cleaning: Wipe the bands with a damp cloth after each use to remove sweat and dirt. Avoid harsh chemicals or abrasive cleaners.
- Drying: Allow the bands to air dry completely before storing. Do not expose them to direct sunlight for prolonged periods, as this can degrade the TPE material.
- Storage: Store the bands in the provided storage bag in a cool, dry place away from extreme temperatures and sharp objects.
- Inspection: Regularly inspect bands for any signs of wear, tears, or nicks before each use. Discontinue use if any damage is observed to prevent injury.

7. Troubleshooting
If you encounter any issues with your SURFOU Resistance Band Set, consider the following:
- Band Snapping/Breaking: While designed to be anti-snap, excessive force, sharp edges, or prolonged wear can cause damage. Always inspect bands before use. If a band breaks, discontinue use immediately.
- Loss of Elasticity: Over time, all elastic materials may lose some elasticity. Ensure proper storage and avoid overstretching beyond recommended limits.
- Door Anchor Slipping: Ensure the door anchor is placed on a sturdy door that closes tightly. The foam stopper must be fully wedged. Do not use on flimsy doors or those with large gaps.
- Discomfort with Handles: Ensure handles are securely attached. If discomfort persists, consider wearing gloves during exercise.
