Will this weaken my muscles?

No — FlexRelief is designed to be worn 1–2 hours a day as a training aid. It gently retrains your posture while keeping your muscles active, so you’re building long-term strength instead of relying on it.

Yes! FlexRelief™ is lightweight and discreet. You can comfortably wear it under a shirt, blouse, or jacket without it being noticeable.

How long should I wear it each day?

Start with 20–30 minutes per day so your body can adjust. Gradually increase to 2–3 hours daily for best results.
