Obliques are a group of muscles located on the sides of the abdomen. They play a crucial role in trunk rotation, lateral flexion, and stabilization of the core. The two main types are the external obliques, which are on the outer sides, and the internal obliques, found beneath them. These muscles are important for various movements, such as twisting and bending. Strengthening the obliques can improve athletic performance and help prevent injuries. Exercises like Russian twists and side planks specifically target these muscles, contributing to overall core strength and stability.
