Next week we are going to have the privilege to have the first-ever long-form interview with record-breaking High School and Club coach Sean Burris. The critical mass system is the essence of his programming for his sprint, hurdle, and jumps athletes. Today I deliver a primer on the training philosophy to provide context to the system that has produced decades of national class speed & power athletes. Most recently the fruits of this system produced world number one outdoor 400-meter dash sprinter Justin Robinson in 2020.
