[0026] FIG. 1 is a perspective view schematically illustrating a user wearing a wearable exercise device according to one embodiment.

[0027] Referring to FIG. 1, a user (H) may be a human. It should be noted that the user (H) may also be an animal. The wearable exercise device may include a wearable member (89) worn on a part of the body of the user (H), a modular actuator (100) that is easily attachable and detachable to the wearable member (89), at least one cable (13, 14) that receives power from the modular actuator (100) and transmits the power to another part of the user's body, a first wearable band (81) worn on a first part of the user, and a second wearable band (82) worn on a second part of the user. The wearable exercise device may include a first cable (83) connecting the modular actuator (100) and the first wearable band (81), and a second cable (83) connecting the modular actuator (100) and the second wearable band (82). Hereinafter, it is to be noted that the first cable (93) may be referred to as a cable.

[0028] The wearable member (89) can be worn on the user's upper body. It should be noted that the location where the wearable member (89) is worn is not limited thereto. For example, the wearable member (89) may be placed on the user's lower body, upper arm, lower arm, or foot.

[0029] The wearing member (89) may include a plurality of wearing stations (89a). The wearing station (89a) refers to an area where the modular actuator (100) is mounted. The wearing station (89a) may be provided with a fixing member (not shown) for fixing the modular actuator (100). For example, the modular actuator (100) may be screw-connected to the wearing station (89a). In another example, the modular actuator (100) may be attached to the wearing station (89a). The wearing station (89a) may be provided with a Velcro structure. The multiple wearing stations (89a) are illustrated as having four on the back, but it should be noted that the number and locations thereof are not limited thereto.

[0030] The first and second parts may be different from the part on which the wearable member (89) is worn. For example, the user's first part may be the user's wrist. For example, the user's second part may be the user's thigh. It should be noted that the positions of the first and second parts are not limited thereto.

[0031] FIG. 2 is a front view schematically illustrating a user wearing a wearable exercise device according to one embodiment. FIG. 3 is a rear view schematically illustrating a user wearing a wearable exercise device according to one embodiment.

[0032] Referring to FIGS. 2 and 3, a wearable member (89) can be worn on a user (H). The wearable member (89) can include a plurality of wearable stations (89a) provided at a front portion or a rear portion with respect to the user (H). A modular actuator (100) can be mounted on any one of the plurality of wearable stations (89a). FIG. 2 illustrates a state in which the modular actuator (100) is mounted on a wearable station (89a) provided at a front portion with respect to the user (H). FIG. 3 illustrates a state in which the modular actuator (100) is mounted on a wearable station (89a) provided at a rear portion with respect to the user (H). A cable (83) can transmit power generated in the modular actuator (100) to the first wearable band (81). For example, the cable (83) may not have elasticity. In this case, the cable (83) can transmit most of the power output from the modular actuator (100) to the user's body. As another example, the cable (83) may have elasticity. In this case, the cable (83) can absorb some of the power output from the modular actuator (100).
