Getting our athlete's bodies back to Square 1 with Shawn Sherman

Helping baseball players perform better by dealing with compensations.

The SQUARE 1 System™ was developed by Shawn Sherman. Shawn earned his Exercise and Sport Science degree from Penn State University and operates a private practice in Western Springs, Illinois. Over the years, Shawn has held numerous industry certifications and therefore understands what and how the conventionalists think and believe. Over the past 25 years, his understanding of movement has evolved from that of an apprentice level to a level of mastery by continually seeking answers to his questions. Because he now intimately and thoroughly understands the most basic components of movement, he brings an unparalleled perspective to the table. Not only does he consistently deliver absolutely amazing results to his clients, he teaches his students to be able to do the same.

Additionally Shawn has consulted with hundreds of elite athletes from many organizations including:

  • United States Olympic Team – wrestling, men's speedskating, women's soccer
  • Canadian Olympic Team – women's soccer
  • Russian Olympic Team – men's swimming
  • Chicago Cubs
  • Chicago White Sox
  • Chicago Blackhawks
  • Chicago Bears
  • Chicago Bulls
  • Indianapolis Colts
  • San Franciso Giants
  • Chicago Red Stars
  • Chicago Wolves
  • ​Vanderbilt University - basketball

Sammy and Shawn discuss:

  • Why the Chicago Cubs hired Shawn to do MATS with their athletes? And what MATS is?
  • After years of using MATS with clients you developed Square 1 to address a different need, why and what is that need?
  • What does Shawn mean by a compensation and how does a dad or typical baseball coach recognize if their athlete are compensating.
  • To help more coaches you developed a program called Signal 6. I remember when you came to Austin in 2018 how when I went through the Signal 6 exercises I gained a bunch of external rotation in my throwing arm. Why is it you developed Signal 6 and how will athletes like me benefit from it?
  • Shawn recently launched the Signal 6 course online, and tells us more about it?
