How much should you move when in the set position for a sprint?

In the set position for a sprint, you should maintain a low center of gravity with your body angled forward while keeping your weight balanced over your hands and feet. Minimal movement is ideal; focus on a quick, explosive push-off rather than excessive shifting. Your arms should be positioned for a strong drive, and any movement should be primarily in response to the starting signal. This helps maximize your acceleration as you transition into the sprint.
