Therefore, when the L-shaped arm 46 is pushed out in the direction of the arrow C, the left large gluteal muscle is trained by adding a circular motion of twisting in the direction of the arrow P in FIG.

  After the training of the left greater gluteus muscle, the right leg is trained by placing the right foot on one step plate 58 and repeating the expansion and contraction of the right foot.

  Also in this case, since one step rate 58 rotates in the direction of the arrow S, as shown by an arrow Q in FIG. 9, a torsional circular motion is added to the right great gluteal muscle and it is trained. As a result, the left and right great gluteal muscles can be trained effectively by expanding and contracting in the overall and muscle fiber direction, and the efficiency of training is improved in this respect.

  In addition, this invention is not limited to the said embodiment, For example, the said stopper 63 can also be abolished. Also in this case, the leg portion is twisted according to the rotation of the step plate 58 by the frictional force between the sole of the shoe or the like and the step plate 58, and the great gluteal muscle can be stretched and stretched in the whole and muscle fiber direction. it can.
