Bent-over row:
Stand with a shoulder-width stance. Grab the barbell, wider than shoulder-width, with an overhand grip. Bending your knees slightly, and your core tight, bend over at the waist keeping your lower back tight. Bending over until your upper body is at a 45-degree bend or lower, pull the bar up towards your lower chest. Keep your elbows as close to your sides as possible. At the top of the movement, you should feel like you are pinching your shoulder blades towards each other. Pause, and return the barbell to its starting position.
Mistakes and Recommendations:
Try to lean forward. Your back should be almost parallel to the floor.
Do not work with your biceps.
Do not round your back. Do not forget about stretching!
Your hands from the elbow to the fist must be straight. Pay attention to this.
Do not take too large weight. It ruins the technique.
Light weight. In this case, you will not achieve muscle gain.
Do not press your elbows against the body.
Do not hold your breath.
Narrow grip is a mistake.
