A key concept Greg Amundson teaches in the CrossFit Goal Setting Course is how to use the mind to command the body.
But sometimes, says the Original Firebreather, the mind follows the body.
"When we are challenged with that negative self-talk, immediately what I want you to do is assess your posture," Amundson says at the CrossFit Experience at the 2012 Reebok CrossFit Games.
"Look at your body. What you'll see is that you're probably not breathing deeply, I betcha that your weight's on your toes, you probably lost your lumbar curve."
To illustrate his point, he has the group do a partner workout: every minute on the minute for 20 minutes, perform one additional burpee. Partners can divvy up burpees however they wish; each person must do at least one rep each round. Before each round, each person must practice his or her positive, powerful posture.
"To get better at the physical skill, what do we do? We practice," Amundson explains. "It's the same thing on the mental side of the house, my friends. We have to practice."
