This application claims priority to Korean Patent Application No. 10-2023-0073572 filed on Jun. 8, 2023, which is hereby incorporated by reference in its entirety.

BACKGROUND OF THE INVENTION

The present disclosure relates to a two-way row machine, and, more particularly, to a two-way row machine including a support unit that is adjustable in height and angle to suit each user's body and allowing a user to adjust the distance between his or her hands and a handle according to the height and angle of the support unit.

A bent over row is a weight training exercise that works the lats, and is a representative exercise for creating balanced back muscles. How to do a bent over row is as follows: Hold dumbbells with your both hands, bend your upper body forward about 80 degrees and slightly bend your knees, bend your arms and pull the dumbbells to the lower part of the pectoralis major muscle, and then return to the original position.

Because beginners have difficulty maintaining proper posture when doing a bent over rows using dumbbells, they may exercise in the wrong posture or put strain on their bodies while exercising and may frequently experience safety accidents such as missing a dumbbell.

As a result, exercise equipment to do a bent over row exercise has been disclosed, but the height and angle of the exercise equipment is fixed and not adjustable to each user's body size, resulting in low exercise efficiency.

Therefore, there is a need for research on a two-way row machine including a support unit that is adjustable in height and angle to suit each user's body and allowing a user to adjust the distance between his or her hands and a handle according to the height and angle of the support unit.
