Description

Technical Field

[0001] The present invention relates to a two-way rowing machine, and more particularly, to a two-way rowing machine provided with a support unit capable of adjusting the height and angle according to the bodies of various users, and capable of adjusting the distance between the user's hands and the handles according to the height and angle of the support unit. Background Art

[0002] As an exercise method for strengthening the latissimus dorsi muscle in weight training, the bent over row is a representative exercise method for shaping balanced back muscles. The bent over row can be performed as follows: Hold dumbbells with both hands, bend the upper body forward by about 80 degrees, take a posture with slightly bent knees, then bend the arms to pull the dumbbells to the lower part of the pectoralis major muscle, and then return to the original posture again.

[0003] At this time, when performing the exercise using dumbbells, beginners may have difficulty performing the exercise in the correct posture, resulting in performing the exercise in the wrong posture or causing harm to the body, and safety accidents such as not grasping the dumbbells firmly also frequently occur.

[0004] Accordingly, although an exercise device capable of performing the bent over row has been disclosed, since the height and angle of the device are fixed, it is impossible to correspond to the body types of various users, resulting in a problem of reduced exercise efficiency.

[0005] Therefore, it is necessary to study a two-way rowing machine provided with a support unit capable of adjusting the height and angle according to the bodies of various users, and capable of adjusting the distance between the user's hands and the handles according to the height and angle of the support unit.
