Starting Blocks

Setting Up your Blocks

Pushing Out instead of Stepping Out. The beginning is particularly good showing a bad setup (typical of first timers)

---

Good overall video for set position analysis as well as the firing out of the blocks. If you are going to skip some skip the beginning be sure not to miss the end when he talks about second step. 

Watch this video, and the various people, multiple times. One time through watch their feet, the next their thighs, the next their arms, the next their heads.
