Abstract

(57) [Abstract] [Challenge] Dumbbells allow the abdominal muscles to be exercised without straining the lower back. SOLUTION: Two dumbbells are temporarily connected and supported on the abdominal muscles with both hands, and the abdominal muscles are exercised while the weight of the dumbbells is applied to the abdominal muscles. It is a feature.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a two-connection dumbbell.

[0002]

[Prior art]

 Conventionally, one or two metal dumbbells are held in one or both hands and used for weighting when exercising muscles of various parts of the body, but hollow drip type plastic is used at the request of the user. The types, materials, colors, etc. have become more diverse as sports have become fashionable.

[0003]

[Problems to be solved by the device]

 The dumbbells that are currently used have been used as a weighting method for muscle training in various parts of the body, but when performing abdominal muscle exercises, dumbbells are not required, and a temporary dumbbell is placed and a supine position is used using another device such as the abdominal muscle table. He has performed abdominal muscles by raising and lifting his upper body or legs. However, since all the movements were performed mainly on the lower back, it often caused back pain. In addition to the conventional method of using dumbbells, it is an object of the present invention to develop a dumbbell that enables abdominal muscles exercise without straining the waist.

[0004]

[Means for Solving the Problems]

 The present invention is a dumbbell whose main feature is that by temporarily connecting and using two dumbbells, the abdominal muscles can be easily exercised without straining the waist, and the structure is that of the connecting device 1. A set of two, consisting of the buffer portion 2 and the weighted portion 3, was made a connection type. If the connecting device is made of metal, a magnet is used. If the connecting device is made of hollow water-filled plastic, a magic tape is considered suitable for light weight purposes. At the part where the dumbbell directly contacts the abdomen, sponge rubber or cushion rubber was used as a cushioning material, and it was attached at two points so that it could be used from either the top or bottom.

[0005]

[Actual form of the invention] By connecting two dumbbells as in the present invention, both knees can be stood in a supine position and a pair of two dumbbells can be stably supported and placed on the abdominal muscles with both hands. If you pull out and relax, the abdominal muscle is pushed downward by the load of the dumbbell and the upper body is slightly raised, and the abdominal muscle contracts and the load of the dumbbell is added. By regaining the relaxation contraction of the abdominal muscles, it was possible to obtain the effect of abdominal muscle exercise. In addition, the lower back pain is hardly exerted during exercise, and the lower back pain can be prevented.
