Feed the Cats: Stiffness with Chris Korfist


“STIFFNESS” is the tenth course of an ambitious Feed the Cats Certification Program created by Tony Holler. 

Feed the Cats is a revolutionary way of training, coaching, and teaching that values specificity, essentialism, performance, and love. After gaining a world-wide following in Track & Field, FTC has now gained a foothold in American football and lacrosse. 

“STIFFNESS” was created by a guest presenter and international speed guru, Chris Korfist. One of the most important features of Feed the Cats is the world-wide network of coaches who have bought into the idea of prioritizing speed and explosiveness while de-empathizing conditioning, toughness, and high volume workouts. The focus on well-rested, happy, and healthy athletes is truly a departure from the grind of the traditional approach. 

“STIFFNESS” gives the background needed for coaches to identify and correct the collapse that inhibits speed. Without stiffness, ground contact times are high and sprinters leak energy. Stiffness has nothing to do with flexibility. 

More courses are on the way!
