Inside Look: PBCardio - Building Endurance and Power

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.

Welcome And Class Overview

Are you ready to live an active lifestyle? Welcome to Behind the Bluff, where we believe every moment of your life is an opportunity to pursue wellness on your terms. I'm your host, Jeff Ford, and today I have the pleasure of wrapping up our series by discussing PB Cardio, a class specifically designed to improve cardiovascular fitness through two distinct approaches: endurance and power.

Rethinking What Cardio Means

SPEAKER_00 0:43

Cardio, for the longest time, has had its own misconception. When many people think of cardio, they think of long, steady-state workouts, getting on a treadmill, an elliptical, and grinding for 30 plus minutes at a time. While steady aerobic training absolutely has value, it's only part of the picture when it comes to training your body effectively. You see, your cardiovascular system benefits from different training intensities because these different training intensities turn on energy pathways. That's exactly why PB cardio is going to alternate between two focused training days.

Endurance Day And VO2 Max

SPEAKER_00 1:34

Day one is endurance. This is the day that most people may not look forward to. However, it is the day that could be most beneficial to our longevity. Our endurance-focused days use VO2 max intervals. We've heard this buzz term for quite some time, and it's been popularized over the last couple of years. VO2max, just so we're clear, refers to your body's ability to use oxygen during exercise. And it is one of the strongest indicators of not only cardiovascular fitness, but now links to your health span and your lifespan. What we wanted to do with our programming is create structure between work and recovery intervals so that the endurance day can help to improve oxygen utilization, cardiovascular fitness, stamina, cardiovascular efficiency, and then just your overall conditioning. Simply put, VO2 max intervals help you sustain effort for longer periods of time.

Power Day And Sprint Intervals

Day two is going to be our power day. It's our second training day, which focuses on sprint interval training. These workouts use short bursts of maximum effort followed by longer recovery periods. A lot of the time when we're training, we just don't give ourselves enough time to recover in order to then elicit the same level of intensity in the next interval. The goal of the power day is to develop speed, anaerobic capacity, and explosiveness. So we are going to begin the class with movements that you're familiar with, but done very intensely in a low volume. You can think ball slams, for example. Between these two formats, think of it this way: Endurance helps you go longer, and power helps you go harder. Somewhere along the lines of fitness, we we told folks that as you get older, it's not safe to go hard. But what we've done is created a format where there is low impact apparatuses, equipment that you will use so that

you can go harder very intensely for those short periods of time. This format is central to my heart. I have always been an endurance junkie. And the concept is very familiar to me because in my endurance racing days, I found a different way to go about training. Over the years, I have completed three Iron Man races, and one thing I learned is that more training isn't always better training. Many of the most successful seasons for me followed a simple approach. I'd have a long day and a short day for each of the disciplines swim bike rung. Long rides, short rides, long runs, short runs. Longer aerobic efforts paired with higher intensity intervals got my fitness level up and sustained it very quickly. The combination for me truly mattered, and now what we're seeing in the science is it matters for our health. If you think about it, the longer sessions I was doing built endurance, the shorter, more intense sessions built power, efficiency, and then speed so that I could hit some of those goal times. This same philosophy applies to our approach behind PB cardio. We are intentionally training different energy systems because they contribute to your overall fitness and most importantly, your long-term health.

Programming Progression And Coaching

SPEAKER_00 5:23

So why does this matter? Well, one of the biggest mistakes people make is only training one of those energy systems. PB Cardio intentionally is going to develop both and will develop both. Every workout has a purpose. Members aren't just working hard. They're following a structured progression built around proven principles. This will be similar to PB Strong, where we will progress your endurance and power over a three-week period in certain time domains, and then in week four, we switch it up again on you. The goal is that our coaching is going to guide effort levels, the intensity that you work at, and provide education so that all of our members start to understand not only what they're doing, but why they're doing it.

Series Takeaways And Closing

SPEAKER_00 6:14

For me, this has been such an incredible series. I hope that the short segments have served you in understanding the approaches and philosophies behind our signature classes. And if there's one thing I hope you take away from this series, it's that these classes weren't created randomly. PB Strong helps you build the foundation. PB Mixed helps you apply that foundation. And PB Cardio helps you improve the engine that powers it all. Together, they create a balanced approach to fitness that can help you stay active, capable, and healthy for years to come. I want to thank you for joining me for this Inside Look series, and I look forward to seeing you in a class soon if you are a member here at Palmetto Bluff. And until next time, keep pursuing wellness on your terms.
