US Patent 10004937 Wearable modular resistance unit

Disclosed is a muscle toning garment with resistance elements, which may be fluid filled dampers. The garment provides resistance to movement throughout an angular range of motion. The garment may be low profile, and worn by a wearer as a primary garment or beneath conventional clothing. Toning may thereby be accomplished throughout the wearer's normal daily activities, without the need for access to conventional exercise equipment. Alternatively, the device may be worn as a supplemental training tool during conventional training techniques. Sensors may be provided for sensing any of a variety of biometric parameters and for determining exerted power or calories consumed.
