In this episode of the Fight Science Made Simple podcast, Coach Adam breaks down HRV (heart rate variability)—the most misunderstood recovery metric in combat sports—and how fighters can use it as a “check engine light” to train hard without running themselves into the ground.

If you’re constantly sore, always second-guessing whether to push or rest, or you feel like you’re living in a cycle of overtraining → burnout → injury, this one is for you.

You’ll learn:

• What HRV actually measures (and what it tells you about your nervous system)
• Why high HRV = better recovery capacity and low HRV can signal accumulated stress
• How to track HRV the right way (and why consistency matters more than the number)
• The biggest mistake fighters make: obsessing over daily scores instead of 7–14 day trends
• How to use HRV to adjust training without getting soft (volume, intensity, frequency, rest days)
• The fastest ways to improve HRV: sleep, nutrition, hydration, stress management, smarter training, and when aerobic work matters
• How HRV removes the guessing, anxiety, and ego-driven decisions that lead to short careers

If you want to train like a savage and stay in the game for the long haul, this episode will upgrade the way you approach recovery—starting today.
