Video Analysis 100 Meter Sprint

In this video you see a new running technique that lots of people are now using. It shows the front and side angle along with the start. Something I need to work on using these running skills is that I need to work on not swinging my arms across my face. I didn't realize until I saw this video that my arms swing in front of my face causing me to go from side to side, so I need to work on that.
