Abstract
A warm-up and weight training device for use on a sports racket is provided which can be readily secured to and removed from the racket's strings. The device includes two housing portions and a plurality of weights positionable in the housing portions. A securing device is used to clamp the housing portions together from opposing sides of the strings while securing the housing and weights to the strings. Protective gaskets are provided as a barrier preventing injury to the strings. The combination of the variable weights and the change in the moment arm based on the position of the invention from the handle, provide a wide range of resistance.
