摘要： An isometric force resistant exercise tool has a left handle form interfaced to a right handle form over an axle shaft locked to the right handle form, the axle shaft supporting a pressure plate, a compress able spring or set of springs, and a compression adjustment handle threaded onto the axle shaft and abutting the compress able spring or spring set, the pressure plate adjacent in assembly to a friction-resistive material fixed on the left handle form, the left handle form including a piston form interfacing with a ring housing on the right handle form, the piston form adjacent in assembly to a friction-resistive material fixed on the right handle form. Gripping the handle forms and rotating the against force resistance exercises one or more muscle groups.
