1
Sit upright on the exercise machine seat with your back firmly against the backrest. Position your feet flat on the footrest. Grasp the handles with an underhand grip (palms facing upward), with arms fully extended in front of you.
2
Adjust the seat height so that the handles align with your mid-chest when arms are extended. Ensure your elbows remain close to your torso throughout the movement. Take a neutral posture with shoulders relaxed.
3
Slowly extend your arms forward and downward in a controlled manner, allowing the cable to pull your hands away from your body. Lower until your elbows are nearly fully extended but not locked, feeling a stretch in the biceps.
4
Initiate the movement by flexing your biceps and pulling the handles back toward your torso in a smooth arc. Continue until your forearms are nearly vertical and elbows are bent at approximately 90 degrees. Squeeze the biceps at the peak contraction, then return slowly to the starting position.
