Sit on a low pulley row machine with a rope attachment.
Grab the ends of the rope using a palms-down grip and sit with your back straight and your knees slightly bent. Tip: Keep your back almost completely vertical and your arms fully extended in front of you. This will be your starting position.
While keeping your torso stationary, lift your elbows and start bending them as you pull the rope towards your neck while exhaling. Throughout the movement your upper arms should remain parallel to the floor. Tip: Continue this motion until your hands are almost next to your ears (the forearms will not be parallel to the floor at the end of the movement as they will be angled a bit upwards) and your elbows are out away from your sides.
After holding for a second or so at the contracted position, come back slowly to the starting position as you inhale. Tip: Again, during no part of the movement should the torso move.
Repeat for the recommended amount of repetitions.
Variation: You can use a straight bar attachment as well or a bench and exercise bands.
