PROBLEM TO BE SOLVED: To provide a lightweight and compact training implement that is held by hand and performs repetitive motion in water using omnidirectional resistance of water in the water, and thereby allows for simultaneous training of two-contradictory muscles in an operation of one reciprocation.SOLUTION: Fingers are put in a hole 4 where fingers are put in, by inserting a hand from a hole 2 of training implement 1 where a palm is put in, a handle part 3 is gripped and held, the repetitive motion such as front/rear, right and left, top and bottom is performed in the water, and thereby a load can simultaneously be given to two-contradictory muscles for controlling each exercise of both directions in one-time repetitive motion and the muscles can be trained by the resistance of the water applied on the surface and backside of a training implement plate surface. The handle part 3 is provided in the gravity center of the training implement 1, and thereby several kinds of repetitive motion is made possible. Consequently, every muscle of an arm can be trained by changing a method of a holding manner and the repetitive motion.SELECTED DRAWING: Figure 1【課題】水中での水の全方位の抵抗を利用して、手に持ち水中での反復運動をすることで、1往復の動作で相反する2か所の筋肉を同時に鍛えることができる軽量でコンパクトなトレーニング器具を提供する。【解決手段】トレーニング器具1の手のひらを入れる穴2から手を挿入して指を入れる穴4に指を入れて取っ手部3を握って保持し、水中にて前後、左右、上下などの反復運動をすることで、トレーニング器具板面の表面と裏面にかかる水の抵抗によって、1回の反復運動で両方向のそれぞれの運動を司る、相反する2か所の筋肉に同時に負荷を与えて鍛えることができる。取っ手部3はトレーニング器具1の重心に設けることで数種類の反復運動を可能にすることを特徴とし、持ち方と反復運動の方法を変えることにより、腕のあらゆる筋肉を鍛えることができる。【選択図】図1
