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 / cm3 to 6 g / cm3, preferably ranging from 4 g / cm3 to 6 g / cm3, so the weight trainer can have a high weight, even fitted with the internal body in small volume.

AI Technical Summary

Benefits of technology

[0007] Accordingly, the present invention provides a weight trainer with heaviness and softness, so hurting a body can be avoided and muscle can be trained.

[0008] To achieve the above advantage and in accordance with the purpose of the invention, as embodied and broadly described herein, the invention provides a weight trainer that 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. Besides, the weight trainer containing the mixture can be comfortably held by a hand or can be comfortably put on a hand, arm, wrist, leg, ankle 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 / cm3 to 6 g / cm3, preferably ranging from 4 g / cm3 to 6 g / cm3, so the weight trainer can have a high weight, even fitted with the internal body in small volume.

Problems solved by technology

The weight trainer, when being slid from a hand, could hurt a body and therefore is specifically unfitted for a child or an older person.

Because the metal lump or metal powder is stiff and has a low flexibility, it could be uneasy to put the weight trainer on, and uncomfortable could be felt when the weight trainer is put on.
