FSMS #17 - HRV for Fighters: How to Train Hard Without Burning Out

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.
