In this episode, Les and Danny are joined by Ken Vick, owner of Velocity Sports Performance, to break down the balance between precision and health in athlete development. They explore how overload, youth specialization, and modern training models impact injury trends across sports. From youth stress fractures to the NBA's rising injury rates, they dive into how coaches can build capacity without breaking athletes down. The Universal Speed Rating is looking for more sports performance businesses to partner with to systemize your speed training and help grow your business.

Hunter Eisenhower, Associate Head Coach, Sports Performance, for Arizona State men's basketball, breaks down his "Force System" training methodology and introduces his Archetype Quadrants.  See how Hunter challenges traditional strength training by focusing on four pillars: High Force (deceleration), Fast Force (speed/elasticity), Slow Force (tendon health), and Human Force (fundamental movement). Learn practical strategies for profiling athletes and designing programs that optimize performance—with or without force plates. Interested in learning more about the Universal Speed Rating?
