In this podcast, Mark Sisson discusses the common phenomenon of an excessive and overly stressful approach to fitness, for which he coined the term "Chronic Cardio" back in 2005. Chronic cardio applies to not only endurance athletes, but to devotees of Crossfit, exercise class junkies, or anyone who is inclined to overdo it on exercise and compromise health in pursuit of fitness. Sisson discusses how to adopt an alternative strategy and philosophy, where you perform the optimal amount of exercise necessary to realize your fitness goals, nurture your health, and promote longevity - as opposed to compromise your health and accelerate aging when drifting into a chronic approach to exercise.
