The Role of the Core and the Trunk in Running in a Water Bag

Today’s podcast features track and speed coach, Chris Korfist.  Chris has been a high school coach in track and football for 3 decades with close to 100 All-State athletes.  He is currently the sprints coach at Homewood Flossmoor high school in Chicago, owns the "Slow Guy Speed School”, and has consulted with professional sports teams all over the world, including the NFL, MLB, NBA, and Rugby League.  Chris has been a favorite podcast guest on this show and is constantly evolving and innovating his methods. Sprinting is a simple, yet complex topic, and one that requires a continual analysis of mechanics, exercises and training models.  There are many ways to train athletes, and with this in mind, it’s important to understand the “first principles” of any training system.  With many first principles taken from the brilliance of the “DB Hammer” training ideals, Chris has steadily evolved his training system, year over year, to the place where it is today. This past season, Homewood Flossmoor won the Illinois state track championship, and won the 4x100m and 4x200m dashes on their way to the title.  Chris’s adjustments to his speed training models worked well, with some athletes chopping off a second or more off of their 200m times from the previous year. On the podcast today, Chris starts by talking about his mental training approach, and some unique mental training elements of this past year’s team.  He then gets into the main changes he utilized this past training year, including reducing the speed endurance component of the work, and replacing it with some potent “AN2” bracket (30-40 second) specialized training for the sprints.  Chris also goes into how he would specialize the exercises for sprinters of different archetypes (stompers vs. slicers) and much more.
