Description

Training hard but still feeling cooked? In this episode, we break down heart rate variability (HRV) so you can stop guessing your recovery and actually see what your nervous system is telling you.

If you’re a CEO, athlete, or high performer who pushes the limits, this is your blueprint for staying out of burnout and keeping your body “hard to kill.”

What You’ll Learn / Highlights

  • What HRV (heart rate variability) really measures and why it’s your nervous system’s “Wi-Fi signal” for stress and recovery.

  • The difference between high vs. low HRV and how it predicts performance, injury risk, and burnout before you feel it.

  • How to use morning HRV as a daily readiness score to adjust training intensity and workload.

  • The lifestyle choices that tank HRV: poor sleep, alcohol, overtraining, under-fueling, emotional stress, late-night eating, travel, and more.

  • The habits that boost HRV: high-quality sleep, breathwork, zone 2 cardio, strength training, sauna, sunlight, hydration/electrolytes, meditation, and micro-breaks.

  • How illness, inflammation, aging, and women’s menstrual cycles affect HRV—and what “weird” spikes or drops can mean.

  • Why relying on “how you feel” is misleading, and how to combine HRV, resting heart rate, VO2 max, and muscle strength to build a truly resilient body.
