Joel Jamieson is a best-selling author and one of the world’s foremost authorities on strength, conditioning, and energy systems. His training strategies have been used by thousands of elite performers and top athletes worldwide, including the Navy SEALS, UFC champions, and dozens of teams from the NFL, NBA, MLS, NCAA, and more. Joel joins us to discuss the importance of aerobic conditioning, how to properly recover, the importance of stress, and more. 

“To me, performance is living a healthy, long life where you’re free of disease and you can do all the things that you love doing.” 

“Exercise, strength, and conditioning activity, they are tools to make our bodies more resilient to stress.” 

“Aging is really just the accumulation of stress over the course of our lives and ultimately our bodies lose the ability to adapt to it and then we start the declining process. If we can make our bodies much more resilient and much more stress capable, then we can delay that process significantly.” 

“You’ve got to get enough sleep. Sleep is the #1 thing. If you’re not getting sleep, you’re severely limited because that’s when your body is the most recovery driven.” 

“I have a really simple rule for most people. 80-90% of the time when you walk out of the gym, you should feel at least as good as when you walked in, if not better. You should not walk out of the gym feeling exhausted and defeated and destroyed.” 

Exercise is the single most powerful tool that we have.” 

“If you have really bad genetics and you have a shitty lifestyle, it can catch up to you pretty fast.”
