Are you overemphasizing cardio in your exercise program?

The answer for almost everyone out there is yes. We are doing too much cardio at the expense of the most beneficial fitness stimulations by far (as known to exercise physiology, not just my opinion): anaerobic system development, true sprinting competency, and true muscular strength and explosive power. The biggest drivers of accelerated aging are sarcopenia (age-related loss of muscle mass) and dinopenia (age-related loss of muscle power and explosiveness).

Falling is essentially the first step in accelerated aging, because the body naturally loses anaerobic muscle power faster than aerobic fitness. This means you can maintain good cardio capacity for decades while becoming increasingly deficient in the qualities that prevent decline and falling—the number one cause of injury and death in Americans over age 65.

In this episode, I explain why brief, explosive exercise is the most important and most neglected fitness stimulation, and why so many popular workouts are still overwhelmingly aerobic. I clarify the difference between aerobic and anaerobic exercise and share exercise physiology data showing that activities like HIIT, CrossFit, group exercise classes, and events like HYROX rely far more on the aerobic system than most people realize.

I also explain how to bring true sprinting back into your program with minimal time commitment and minimal risk of burnout, using short, fully rested efforts that preserve muscle power, resilience, and healthy aging.

TIMESTAMPS:

Are you over-emphasizing cardio in your exercise program? [01:05]

Falling is the first step in accelerated aging. [02:56]

Brief explosive exercises are recommended. [03:45]

What is the difference between aerobic and anaerobic exercise? [04:50]

All your intense activies like HIIT, Crossfit, and anything that lasts longer than a few minutes are primarily aerobic. [11:40]

High Rocks is a template of challenges that stay the same in every competition. It is 98% aerobic. [14:00]

Instead of all the endurance work you do now, something that uses minimal time, minimal risk of burnout, you can develop your power. Throw is the sprint routine that Brad talks about. [21:40]

Rest and relax in between your efforts. Put a true sprint workout into the mix. [26:48]
