In this episode, we discuss how metcons are characterized by severe and extreme intensity exercise that is often intermittent in the context of each task, but continuous in the context of the workout.

We cover:

• the fatigue mechanisms of severe intensity exercise
• the fatigue mechanisms of extreme intensity exercise
• why severe vs. extreme intensity matters
• which movements are severe intensity and which ones are extreme
  • Weightlifting and % of 1RM
  • Gymnastics and movement selection
  • Monostructural modalities and pace
• a discussion of continuous vs. intermittent exercise and how metcons defy these labels
