Understanding how each muscle works may help you improve your running form, technique, and performance.

Core muscles:
Located in your torso and pelvis, your core muscles connect your upper body to your lower body. A strong core helps to maintain proper posture, balance, and form while running. It can also help to properly align your spine, pelvis, and lower body.
