On episode 35 I sat down with Chris Korfist, Co founder of track football consortium and RPR. Chris is well known for speed training and sprints and that's exactly what a good portion of todays conversation centers around. We begin the conversation by discussing how Coach Korfist can best identify drivers in his athletes and how he utilizes that to examine and justify the implementation of training. Chris first discusses how he can utilize RPR to help inform him about movement competencies and potential compensatory patterns. We also discuss how video analysis can help to inform about the drivers and movement preferences of athletes. Coach Korfist discusses some of the more common movement flaws that he encounters with athletes and the negative ramifications for less than optimal movement choices. Coach korfist shares that many times he encounters runners that are pushers or quad dominant. He shares how stiff legged runs or prime times are a good option to teach athletes how to properly utilize their hamstrings and find proper foot placement. We also discuss the proper posture for stiff legged runs and why we may encounter athletes with excessive lean.  Coach Korfist shares programming considerations based on profile are they muscle bound or are they more elastic in nature. If athletes are more muscle bound one of the things that stands out immediately is that they will need training that helps provide stiffness in order to get the system primed and ready to go. Indicators such as vertical jump, ankle rocker capabilities or ankle rocker hops help to inform programming needs for elastic athletes. We turn our conversation to weight room practices and discuss the best manner to progress athletes to keep speed the primary consideration. Coach Korfist shares some of his general strength methods and his rationale with Triphasic. He also shares how to keep athletes reflexive and springy when training strength movements. Coach Korfist shares a good point that athletic movement do not fit the generally profile of powerlifting or oly lifting. Greasing the groove is to the detriment of athletic development for those that wish to move in an athletic and dynamic manner.  We turn our attention to the 1080 and coach Korfist shares how he starts his athletes on overspeed training. He discusses some of his rationale for starting athletes on overspeed early, it helps examine how they respond to moving fast, is there fear? Can they turn over properly. Coach Korfist also likes to use mini hurdles to encourage certain turn over patterns. Coach Korfist utilizes a variety of methods depending on the desired adaptation. Coach Korfist discusses how he utilizes the power of competition and has a leader board to help gamify and push athletes when doing resisted sprints. We also discuss some of the possible benefits of utilizing the 1080 for agilities as well as sporting practices.  We end the conversation by discussing the ideas behind his article Too many notes that coach Korfist published a while back on Simplifaster. This article stood out in stark contrast to how I typically view Coach Korfist. I see coach Korfist as being an experimenter as well as a trainer that is able to provide individualized training means. Coach Korfist is all of the things mentioned earlier, however, he also likes to keep it simple and realizes like his article states" sometimes its what you don't play. We discuss the absolute stacked line up for TFC 2021 as well as the new RPR courses that are being offered both virtually and in person.
