Question: 1 / 400

Which muscle is primarily targeted during a lat pull-down?

Trapezius

Biceps

Latissimus dorsi

The lat pull-down is an exercise that primarily targets the latissimus dorsi muscle, which is a large, flat muscle located on the back. This muscle is responsible for several movements of the shoulder, including adduction, extension, and internal rotation of the arm. During the lat pull-down, as you pull the bar down towards your chest, the latissimus dorsi contracts to bring the arms down, effectively engaging and strengthening this muscle.

While other muscles such as the trapezius, biceps, and deltoids assist during the movement, the latissimus dorsi is the main muscle worked. The exercise is particularly effective for developing the width of the back, contributing to an overall V-taper physique. Understanding the primary muscle targeted in exercises like the lat pull-down is crucial for designing effective workout programs that focus on specific muscle development.
