Why choose this stretcher Adjustable angles let you tailor intensity and progress safely. Non-slip, waterproof surface stays stable and is easy to clean. Suitable for everyday use across multiple environments (home, office, gym, yoga). Usage tips Start at the lowest angle and increase gradually as flexibility and comfort improve.

Use on a flat, stable surface and ensure both feet are positioned securely on the anti-slip surface. Note: angles and features are fixed as specified: 8.5°, 17°, 25.5°, 34°.
