arm members

34 and 36 are in the lowered state, and cushions an impact at the time of the abutment. In this lowered state, the pair of

arm members

34, 36 extend substantially vertically downward due to their own weight.

When performing dumbbell fly training using this training machine, do as follows. Referring mainly to FIGS. 5 to 8, the trainee P sleeps on the back so that the head is on the front side of the bench portion 14 of the machine body, and hangs down with both feet straddling the bench portion 14. . In such a state, both arms are spread on both sides and the first grip portion 48 of the gripping

means

28, 30 in the lowered state is gripped. In this gripping state, both hands are facing inward to grip the first grip portion 48.

Then, the arms are lifted upward while moving the arms inward from the lowered state shown in FIGS. 5 and 7, and are lifted up to the raised state shown in FIGS. Training is performed by lowering to a lowered state shown in FIG. 5 (or an intermediate state between the lowered state and the raised state), and repeating such lifting and lowering operations.

In this lifting operation, as can be understood from FIG. 5, the pair of

arm members

34 and 36 of the

swing arms

24 and 26 are provided with the shaft member 32 (the swing axis line in which the central axis of the shaft member 32 extends in the front-rear direction). The load for moving the swing arms 24 and 26 (and the weight 66 attached thereto) to the inside is mainly at the initial stage of lifting. Although acting on the joints and tendons, at this time, the load acting on the joints and tendons of both arms is small, and training gentle to the joints and tendons can be performed.

The load acting through the

swing arms

24 and 26 increases as the

swing arms

24 and 26 are raised, but both arms of the trainee P gradually extend as the

swing arms

24 and 26 are lifted. Thus, the load acts on the great pectoral muscles instead of the joints and tendons of both arms, and the pectoral pectoral muscles can be trained without increasing the load on the joints and tendons.

Then, when the swinging

arms

24 and 26 are lifted up, the swinging

arms

24 and 26 extend in a substantially horizontal direction as shown in FIGS. 6 and 8, and as can be understood from FIG. 24, 26 (and the weight 66 attached to them) is the largest load and acts on the pectoralis major muscle via both arms, thereby effectively training the pectoral pectoral muscle of the trainee P. be able to.

As described above, in this training machine, when the

swing arms

24 and 26 are lowered, the load acting on the joints and tendons of both arms is small, and when the

swing arms

24 and 26 are lifted, A large load acts on the pectoralis major muscle, thus effectively performing dumbbell fly training that is gentle on joints and tendons.

Also, when performing dumbbell press training using this training machine, it is performed as follows. Referring mainly to FIG. 9 and FIG. 10, the trainer P sleeps on his / her back so that the head is on the front side of the bench portion 14 of the machine body, and holds both feet on the bench portion 14 as in the dumbbell fly training. It hangs down as if straddling. In this dumbbell press training, as is easily understood by comparing FIGS. 9 and 10 with FIGS. 7 and 8, the dumbbell press training is located shallower on the bench portion 14 than in the dumbbell fly training (that is, front and rear). (It is located on the rear side in the direction). In such a state, both arms are spread on both sides and the gripping member 54 of the second grip portion 50 of the gripping

means

28, 30 in the lowered state is gripped. In this gripping state, both hands grip the second grip portion 50 toward the front side of the trainee P.

9 is lifted upward while moving both arms inward from the lowered state shown in FIG. 9 and lifted to the raised state shown in FIG. 10. After the lifting operation, the arms are moved outwardly while being lowered as shown in FIG. Or an intermediate state between a lowered state and an elevated state), and training is performed by repeating such lifting and lowering operations.

During the lifting operation, as described above, the pair of

arm members

34 and 36 of the

swing arms

24 and 26 is the shaft member 32 (the central axis of the shaft member 32 forms a swing axis extending in the front-rear direction). In the initial stage of lifting, a load for moving the swing arms 24 and 26 (and the weight 66 attached thereto) inward mainly acts on the joints and tendons of both arms. The load acting on the joints and tendons of both arms is small, and training that is gentle to the joints and tendons can be performed.

As with the dumbbell fly training, the load acting through the

swing arms

24 and 26 increases as the

swing arms

24 and 26 are raised, but the training is performed as the

swing arms

24 and 26 are lifted. Both arms of the person P gradually extend, and such a load acts on the great pectoral muscles instead of the joints and tendons of both arms. When the swinging

arms

24 and 26 are lifted up, the swinging

arms

24 and 26 extend in a substantially horizontal direction, and the load on the swinging arms 24 and 26 (and the weight 66 attached thereto) becomes the largest. It acts on the great pectoral muscle through both arms.

Also in the dumbbell press training using this training machine, when the

swing arms

24 and 26 are lowered, the load acting on the joints and tendons of both arms is small, and the

swing arms

24 and 26 are lifted. The large load acts on the great pectoral muscles, and thus it is possible to effectively perform joint and tendon-friendly training.

As mentioned above, although one embodiment of the training machine according to the present invention has been described, the present invention is not limited to such an embodiment, and various changes and modifications can be made without departing from the scope of the present invention.

For example, in the above-described embodiment, the first grip portion 48 and the second grip portion 50 are provided on the gripping shaft member 38, but the second grip means 50 can be omitted when not used for dumbbell press training. .

Further, for example, in the above-described embodiment, the shaft member 32 is attached to the support column portion 6 (8), and the pair of

arm members

34, 36 are provided at both ends of the shaft member 32 protruding from the support column portion 6 (8). The gripping means 28 (30) is mounted between the

arm members

34 and 36, but instead of such a configuration, for example, a pair of support portions is provided at the upper end portion of the support column portion 6 (8). It is also possible to provide a shaft member between the support portions, attach an arm member to the shaft member (a portion between the pair of support portions), and attach a gripping means to the tip of the arm member.

In the training machine of the present invention, in the dumbbell fly training, the swing arm is swung up and down around the swing axis extending in the front-rear direction, so that the swing arm is lowered, in other words, the arm is bent. , The swing arm extends downward and the load acting on the arm is small. In such a state, the burden on the joint and tendon is small, and the joint and tendon can be trained gently. Also, when the swing arm is raised, in other words, when the arm is extended, the swing arm extends in a substantially horizontal direction and the load acting on the arm increases, and the pectoral muscles can be trained with a large load. it can.
