Are you getting the balance between Zone 2 and HIIT right? I’m exploring how an 80/20 split by sessions, with most training at lower intensity and select high-intensity work, supports results without burning you out.


This clip explores why all-HIIT programs often feel unsustainable and can lead to fatigue or injuries, what 80/20 really means when you count sessions rather than minutes, and why only about 5 to 10 percent of total minutes across a season tend to be truly high intensity in athletic programs. We discuss how Zone 2 should be harder than easy cruising to drive mitochondrial adaptations, practical ways for busy people to blend mostly Zone 2 with a small dose of intensity toward the end of some sessions, and why complete off days can be more restorative than so-called active recovery. I also share my experience of feeling awful doing fasted HIIT, and we touch on how women may find certain efforts tougher due to muscle fibre differences related to ATP production. As a nutritionist and health communicator, I connect the training plan with recovery needs, including the role of rest for immune health.
