To strengthen the lats effectively in the frontal plane, the pull-up is a highly beneficial exercise. When performing a pull-up, the arms are pulled down toward the body while the body is raised upwards against gravity, primarily targeting the latissimus dorsi muscles. This movement emphasizes the pull that aligns with the frontal plane, which is characterized by motions that occur from side to side.

The pull-up requires significant engagement of the lats, especially as the body lifts itself upward. This vertical movement pattern challenges the muscles effectively and reinforces the strength-building process in a functional manner. It is also a compound movement, incorporating other muscles such as the biceps and shoulders, which contribute to overall upper body strength.

While other exercises, such as the chin-up and lat pull-down, can also work the lats, they are either more aligned with pulling movements that affect the sagittal plane or place the body in a different position that can alter the engagement of the lats compared to the pull-up. The seated row is excellent for back development but primarily focuses on horizontal pulling, which doesn't align with the frontal plane during the movement.
