Casey Glass is a strength and conditioning coach who works with special operators in the United States military including special operators preparing to screen for Tier One units, the most elite military units in the world. We talk about training and stress management techniques from the world of special operations that anyone can use to improve mental and physical performance in work, in life and in sport. Normally I would steer you to a guest's social media or website. While Casey graciously shares her knowledge in this interview, due to the nature of her work, you won't find her on the internet. Casey got her start working in collegiate strength and conditioning for Olympic sports before shifting to work with tactical athletes. This marks the 50th episode of Choose the Hard Way and I want to say thank you to everyone who listens to the show and shares it with their friends. When I started out three years ago, I had no idea there would be such an overwhelming response to the show or that it would get this big. Thanks for listening, thanks for helping Choose the Hard Way grow, and I'm excited to keep growing it with your help.
