I explore the science, benefits, and potential downsides of cold plunges—discussing how they reduce inflammation, build mental toughness, and help with rapid recovery, but might blunt long-term training adaptations. Then, I shift gears to heat training, unpacking how saunas, hot baths, and even layering up during workouts can improve blood plasma volume, VO₂ max, and heat tolerance while boosting overall endurance.

With a mix of personal experience, coaching insights, studies, and more, I help you understand when and how to use these tools for maximum benefit. Plus, I outline how I integrate them into my own training schedule.

Should you heat things up or chill out? Tune in to learn how to adapt these strategies for your goals—and avoid the bro-culture traps along the way.
