Abstract: A load sensing device for use with an exercise band is disclosed. The load sensing device comprises a band of resilient material, a load sensor attached to the band and configured to measure an extension force applied to the band, and an electronic circuit configured to measure the applied extension force and to wirelessly transmit a signal representative of the applied extension force to a receiver. The band of resilient material protects the load sensor and the electronic circuit from damage by at least partially surrounding them.
