Weight trainer

Abstract

A weight trainer includes a thermo plastic elastomer and a solid powder, wherein the thermo plastic elastomer and the solid powder are mixed. The mixture is flexible and is tailored to various designs for the weight trainer. The weight trainer containing the mixture can be comfortably held by a hand or can be comfortably put on a hand, wrist, leg, or waist. The internal body in the weight trainer, due to being mixed with the solid powder, has an extremely high density ranging from 0.5 g/cm 3 to 6 g/cm 3 , preferably ranging from 4 g/cm 3 to 6 g/cm 3 , so the weight trainer can have a high weight, even fitted with the internal body in small volume.
