To be a great hurdler one needs great technique and speed. To develop hurdlers you need drills to develop both speed and technique. Many hurdle drills are full speed activities, however, there are some exercises that are conducted at sub-maximal speeds. In the video below Vince Anderson, assistant coach for NCAA Track and Field powerhouse Texas A&M, shows two sub-max drills that he uses to increase the leg frequency of his hurdlers.
The drills are from a DVD that contains several drills for hurdlers. To learn more about the DVD that these drills came from click the link Texas A&M Track & Field Series – Drills and Progressions for Championship Sprint Hurdles
