Episode Details

Cardio has a branding problem. Too many of us still picture long, steady treadmill miles and call it a day, even though our bodies adapt best when we train across different intensities. Jeff Ford closes out the Inside Look series by unpacking PB Cardio, a two-day format built to improve cardiovascular fitness through endurance and power, not just effort for effort’s sake.

We break down Day One: endurance training with VO2 max intervals. VO2 max is your body’s ability to use oxygen during exercise, and it’s one of the strongest predictors of cardiovascular fitness. Jeff explains why it also matters for longevity, healthspan, and real-world stamina, plus how structured work-to-recovery intervals help you build cardiovascular efficiency and conditioning you can actually feel.

Then we shift to Day Two: power training through sprint interval training. Short bursts of max effort with longer recovery build speed, anaerobic capacity, and explosiveness, while smarter recovery lets you repeat high intensity safely and consistently. Jeff also shares lessons from Ironman racing that reinforce a simple truth: more training isn’t always better training, but balanced training usually is.

If you want a practical plan for endurance, power, and long-term health, press play. Subscribe, share this with a friend who “hates cardio,” and leave a review with the biggest shift you’re making in your training.
