Why Slow Guy Speed School

Slow Guy Speed School is built on testing, not guessing.

Chris Korfist has produced 100+ All-State athletes at Slow Guy Speed School and coached 33 All-State sprint relays and 29 All-State sprinters at the high school level. Slow Guy Speed School trains NFL stars, Olympians, and middle schoolers side by side, because the same testing process works at every level: film the movement, measure the pattern, build the program around the athlete in front of us.

  • Film the movement.
  • Measure the pattern.
  • Build the program.

From the field

From state meets to coaching rooms around the world.

Every level

Same testing process, every level.

From NFL stars to middle schoolers, the work starts the same way: film the movement, measure the pattern, build the program around the athlete in front of us.

How It Works

Three steps. Every athlete, every time.

01

Athletic Assessment

Every athlete starts on camera. We record and break down movement patterns before a single rep gets programmed, so the plan is built on what's actually happening, not a guess.

A Customized Program

Decades of coaching experience meets Reflexive Performance Reset technique, targeting the neuromuscular pathways the assessment flags. No generic speed-camp script.
