| Problem | Possible Cause | Solution |
|---|---|---|
| Exerciser slides during use. | Not on non-slip mat; mat not properly placed; surface too smooth. | Ensure the exerciser is placed on the provided non-slip mat. Verify the mat is flat and clean. Use on a carpeted surface if possible, or consider additional anti-slip measures. |
