BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention generally relates to a weight trainer. More particularly, the present invention relates to a weight trainer containing the mixture of a solid powder and a thermo plastic elastomer. [0004] 2. Description of the Related Art [0005] In the trend towards health care, weight training is popular and easily reaches the effect of exercising. If weight training lasts for a long term, vigorous and graceful muscle can be turned out. Some conventional weight trainer, made of iron lump, iron powder, iron flake or iron bead, such as dumbbells or a sand bag, is stiff and has a weight of several pounds or kilograms. 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. [0006] Additionally, in regards to some weight trainers, a metal lump or metal powder is enclosed by a cloth or rubber package. The weight trainer can be attached to some portion of the body through a Velcro tape. 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. SUMMARY OF THE INVENTION [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/cm.sup.3 to 6 g/cm.sup.3, preferably ranging from 4 g/cm.sup.3 to 6 g/cm.sup.3, so the weight trainer can have a high weight, even fitted with the internal body in small volume. [0009] Preferably, each particle of the solider has a largest transverse dimension of less than 100 microns. Preferably, the solid powder includes iron powder [0010] Preferably, the weight trainer further includes an enclosure, such as cloth or rubber, enclosing an internal body containing the thermo plastic elastomer and the solid powder. The internal body has 60 to 85 weight percent of the solid powder, for example. [0011] Preferably, the weight trainer further includes an oil mixed with the thermo plastic elastomer and the solid powder. [0012] It is to be understood that both the foregoing general description and the following detailed description are exemplary, and are intended to provide further explanation of the invention as claimed.
