Most people argue over HIIT vs steady state cardio, but the truth is—you need both.
If you want to recover faster, build real-world endurance, and keep your strength as you age, you have to understand how to train your cardiovascular system the right way.

In this episode, Judd Lienhard—former Army Ranger, college linebacker, and performance coach for 15+ years—breaks down how your body actually fuels exercise, why your cardio base supports your weight training, and how to balance low-intensity aerobic work with high-intensity intervals for maximum results after 30.

He explains the real difference between aerobic and anaerobic systems, how to improve VO₂ max and mitochondrial health, and why weight training is also cardio when structured correctly. You’ll learn how to blend Zone 2 conditioning, HIIT intervals, and strength training into one plan that makes you leaner, stronger, and more athletic for life.

In This Episode

• HIIT vs steady state: which is better and why
• The science behind energy systems (without the jargon)
• How to train your VO₂ max for longevity and performance
• The ideal weekly balance of cardio and strength after 30
• How to use weights to build endurance and power
• Why most people aren’t “out of shape”—they’re under-conditioned
