How can I improve my running form to incorporate a more efficient forward leg swing?

To improve your running form for a more efficient forward leg swing, focus on increasing your hip flexibility and strength, maintaining a slight forward lean while running, and engaging your core muscles to support your posture. Additionally, work on landing with your foot directly under your body and pushing off with power from your toes. Regular practice and feedback from a coach or experienced runner can also help you refine your technique.
