A seated row machine is a piece of fitness equipment that is used to target and strengthen the muscles in the back, specifically the latissimus dorsi, rhomboids, and trapezius muscles. It typically consists of a padded seat, footrests, and a handlebar or pulley system that allows the user to perform rowing movements while seated. To use a seated row machine, adjust the seat and footrests to a comfortable position. Sit upright with your feet securely placed on the footrests and grasp the handlebar with an overhand grip. Pull the handlebar towards your chest while keeping your back straight and shoulders down. Squeeze your shoulder blades together as you pull the handlebar towards you, then slowly release it back to the starting position. Performing seated rows on a row machine can help improve back strength, posture, and overall upper body muscle development. It is important to use proper form and technique to avoid injury and maximize the effectiveness of the exercise.
