Description
Fix your arm strike and run faster. A straight arm is a longer lever, which means it's slower to swing. Since your arm cadence is locked to your leg cadence, slow arms drag your stride rate down and glue you to the ground longer. Ground contact time is where sprint speed lives. Bend the elbow, tighten the lever, snap the arms. The legs follow.
