Proper Sprint Technique
Like anything else, you'll want to master proper form while sprinting. According to Boldon, your hands should swing up to eye level but not above it, and you want to keep them away from your chin or ears. Your shoulders should always be relaxed, and your hips should be underneath you as apposed to trailing behind you, he explained. Your feet should land "directly under your body, not too far in front or behind your center of mass," he said.
Taylor said to "focus on staying tall (pretend there's a string attached to the top of your head) and generating a high knee lift by bringing the ankle around the opposite knee when sprinting."
