Abstract: The invention discloses inflatable flexible dumbbell and the manufacturing method, comprising first counterweight section, second counterweight section and rigid grip section; First counterweight section includes first inflatable bladder having first air cavity; second counterweight section includes second inflatable bladder having second air cavity; grip includes plastic-textured rigid tubular body having third air cavity; rigid tubular body, first inflatable bladder, second inflatable bladder are made of plastic materials, fillers are arranged in first air cavity, second air cavity, third air cavity; rigid tubular body, first inflatable bladder, second inflatable bladder are made of plastic materials and distributed by rotational molding and separated by a bonding film; the inflatable bladder and the gas contained therein avoid the risk that the dumbbell hits people due to accidental falling, and there is filler in air cavity of grip section, so the volume of the dumbbell is smaller under the premise of equ

Abstract: An abdominal exercise wheel includes a base provided with a pair of upwardly curved grip rods. The base is provided with three groups of pulley assemblies at a lower part of the base. The pulley assemblies are triangularly distributed below the base. A position of the pulley assemblies enables the pulley assemblies to support the base more stably while reducing side-turn over during use. Each pulley assembly includes a pulley seat and a pulley rotatably connected onto the pulley seat. The base is provided with elbow support members at two sides of the base, respectively. Each elbow support member includes a plurality of elbow support sheets. The plurality of elbow support sheets and corresponding elbow support surfaces are increased to reduce detachment of a user's elbows from the elbow support sheet during use.

Abstract: The present invention relates to the technical field of an abdominal exercise wheel, and specifically discloses an abdominal exercise wheel, including a base. The base is provided thereon with an upwardly curved grip rod. The base is provided with three groups of pulley assemblies at the lower part. The pulley assemblies are triangularly distributed below the base. The pulley assembly includes a pulley seat and a pulley rotatably connected onto the pulley seat. The base is provided with elbow support members at the two sides. The elbow support member includes a plurality of elbow support sheets. The position of the pulley assembly is redesigned, so that the pulley assembly supports the base more stably and are less likely to side-turn over during use. The elbow support sheet and the elbow support surface are increased, so that the elbow is difficult to be detached from the elbow support sheet.
