Therefore, the above configuration has the following effects. That is, in the knee muscle strengthening device 1 of the present embodiment, the knee can bend and stretch in the air by performing a stepping exercise in the air while sitting on the chair 7 and wearing the knee muscle strengthening device 1. As a result, muscles around the knee (for example, muscles such as ankle, shin, knee, and thigh) can be strengthened without applying a load to the user's knee cartilage. You can even sit on the bed. In addition, one leg can be attached to the floor and one leg can bend and stretch in the air alternately. Healthy people can also use it to strengthen their leg strength at home.

  In the knee muscle strengthening device 1 of the present embodiment, muscles around the knee can be strengthened without applying a load to the cartilage of the knee, so that the pain is eased and the probability of complete healing is high. Furthermore, if it is performed in parallel with the drinking of cartilage components such as dietary supplements such as chondroitin and glucosamine, the establishment of healing is further increased. As one example, arthritis accompanied by water accumulation in both knees and strong pain disappeared almost completely in 2 months using the knee muscle strengthening device 1 of the present embodiment, and was almost completely cured in 4 months.

  Therefore, in the knee muscle strengthening device 1 according to the present embodiment, the muscles around the knee can be strengthened without giving a burden to the knee cartilage, and the leg strength in the sports gym and the leg strength in the rehabilitation facility can be strengthened. Further, it is possible to provide a knee muscle strengthening device capable of improving knee joint pain, strengthening leg strength at home, and improving knee joint pain.

  Further, in the knee muscle strengthening device 1 of the present embodiment, since it is not used for walking, there is no problem even if the left and right shapes are the same. Accordingly, only one type of molding die for the knee muscle strengthening device 1 is required, and the manufacturing cost can be reduced and provided at a low cost.

  Further, when the knee muscle strengthening device 1 is used, the weight main body 5a is disposed in front of the recess 4 and the embedding tool 5b is disposed behind the weight main body 5a, and the weight main body is disposed behind the recess 4. One of the second set state in which 5a is arranged and the filling tool 5b is arranged in front of the weight main body 5a can be selected as necessary. Therefore, for example, in the first set state, the center of gravity position of the footrest portion 2 can be set in front of the second set state, so that even if the same weight main body 5a and filling tool 5b are used, two types are used. The load (load) condition can be switched and set. Therefore, the first set state and the second set state can be switched and used properly, and variations in knee muscle strengthening exercise can be increased.
