Lateral muscles are a group of muscles located on the sides of the body. They play a crucial role in movements such as bending, twisting, and stabilizing the torso. These muscles help maintain balance and support various physical activities, including sports and daily tasks. One of the key lateral muscles is the latissimus dorsi, which extends from the lower back to the upper arm. This muscle is essential for actions like pulling and lifting. Other lateral muscles include the obliques, which assist in rotating the trunk and bending sideways, contributing to overall core strength and stability.
