Abstract

Abstract A gymnastics/exercising device for universal use, and especially for places of employment where the work entails one-sided or static strains. The equipment comprises two handles connected by an inelastic rope whose length between the handles can be varied. The end sections of the handles are expanded in relation to the middle section of the handle. The rope is secured to the middle section of the handle near one of the expanded end sections of the handle, and is intended to be wound around the middle section of the handle. One of the end sections of the handle has a larger diameter than the other. This end section has an external, annular depression therein, intended to receive and support the little finger of the user's hand during use. The other end section is provided with longitudinal flutes intended to facilitate the finger's grip when the handle is being turned.
