It includes a cushioned wearable base (such as a belt, vest, strap, or harness), an integrated resistance and control module, LED visual indicators, and wireless connectivity to a companion application.

[0006] A central controller dynamically modulates resistance using data from embedded sensors that monitor motion, temperature, and user load. Optional heat and massage elements promote muscle recovery and comfort.

[0007] An AI-based calibration routine learns user patterns to personalize resistance profiles and maintain consistent performance.

[0008] The module can be worn on the waist, torso, or limbs and detaches for stand-alone or handle-mounted use.BRIEF DESCRIPTION OF THE DRAWINGS

[73] ; a hydraulic valve controls fluid flow for smooth braking. In band-based embodiments, spool

[75] couples to drive assembly

[71] and mechanism

[72] to store and release tension under controlled load. Coil spring
