It's amazing how many sprinters loose speed through external rotation. Learn some quick fixes for one of the most common speed killers out there.
When sprinting you want to line up your forces and hit it as hard as you can. Any external rotation will cause your speed to drop. Something as simple as a slight head movement can carry over into the hands and the feet causing wasted movement and slower times. On top of all of that if you're in a competition and step out of your lane you can get disqualified.

In this lesson coach Harnden teaches the importance of avoiding external rotation. He also provides some practical sprinting tips and drills to work on keeping things lined up. Remember, the fastest way to get from point A to point B is a straight line!
