In the training device according to the present invention,
In particular, when the lower support member 3a is separable from the tread plate 2 or the lower support member 3a is foldable with respect to the tread plate 2, the portability can be improved by disassembling or folding the device.

Other Embodiments FIG. 20 shows a state in which the intermediate bending piece 8 is omitted and the grip handle 9 is directly pivotally attached to the front split piece 75 in the training apparatus having the above-mentioned configuration. In the training device having such a configuration, since the intermediate holding piece 8 does not exist, the smoothness in rotating the handle 10 to the lower position may be impaired as compared with the above-described embodiment, but the handle is It is possible to smoothly swing the handle down to a position where the grip handle 9 is present in the vicinity of the abdomen on the front side of the user, compared to the one shown in FIG.

The pivotal connection between the handle body and the grip handle, the pivotal connection between the handle body and the intermediate bending piece, and the pivotal connection between the intermediate bending piece and the grip handle, have a certain degree of play. With this configuration, the play can replace the rotation of the front divided piece around the axis.

The load means 11 according to the present invention is, in short,
The user holds the handle 9 and lifts the handle 10 to the upper position A.
In order to rotate from the first position to the lower position state B or to further rotate the position, any known means can be used as long as it is a means that resists this turning operation.
As an example, a load adjusting unit using hydraulic pressure applied to a door closer can be used, for example. When such a load means is employed, the load can be easily adjusted according to the muscle strength of the user by adjusting the hydraulic valve.

In particular, as shown in the above embodiment, when the load means 11 is constituted by using the coil spring 63, the coil spring can be exchanged or a coil spring having a different spring constant is provided. By preparing a plurality of types of rotary load devices and attaching a required rotary load device to the column 3, it is possible to cope with the level of muscle strength of the user.
