Today, I'm taking you through my latest blood testing with Vitals Vault and sharing the biomarkers I pay the most attention to for health and performance.

I explain why I track triglycerides-to-HDL ratio, fasting insulin, vitamin D, and especially testosterone, free testosterone, and SHBG—and why I've tested my testosterone about 30 times over the past six years.

I also break down how training stress can affect testosterone, why chronic cardio can work against testosterone optimization, and the lifestyle factors I focus on to keep my levels in a healthy range. Plus, I explain why total testosterone, free testosterone, and SHBG all matter—and share one surprising factor that can affect testosterone and longevity: your love relationship!

 

TIMESTAMPS:

Brad talks about the ease and importance of getting blood analysis regularly to maintain your health. [01:01]

Triglycerides should be under 100 and you usually have to request fasting insulin and Vitamin D. Also important is the overall sex hormone level. [04:34]

If you're metabolically unhealthy and you're carrying around visceral fat, and you take outside testosterone, you are likely to aromatize that extra testosterone, and that means converting it into estrogen. [07:30]

Sleep is a great way to elevate the testosterone level. You have to get the junk food out of your diet. Make sure your exercise is in the best way.  Chronic cardio is known to tank testosterone. [11:49]

The B.rad Podcast

Today, we've been conditioned to believe that accelerated aging is normal — that getting older means slowing down, losing our competitive edge, and watching others from the sidelines. Brad Kearns is living proof that's a lie. A New York Times bestselling author, former world #3 ranked professional triathlete, and current world-ranked masters high jumper and 400-meter runner, Brad is competing and excelling into his 60s.

The B.rad Podcast informs and inspires you to see what's possible at any age. Every episode cuts through the hype and misinformation on the topics that matter most: ancestral nutrition and diet strategies that strip body fat and restore energy; training methods that build strength, power, speed, and endurance without destroying your body; recovery protocols that keep you performing at your peak; and the mindset shifts that help you thrive as you age instead of simply survive. This show offers a refreshing alternative to slowing down, giving up, and fading away.

Whether you're a competitive athlete looking to extend your prime, someone battling fatigue and frustration with conventional health advice, or simply a person who refuses to go quietly into a slower, smaller life — the B.rad Podcast was built for you. No shortcuts. No hype. Just world-class guests and actionable tips to help you dial in all areas of healthy living and lifelong functional fitness.

Enjoy step-by-step actionable protocols from Brad, as well as prominent guests like Mark Sisson, Dr. Paul Saladino, Ben Greenfield, Shawn Stevenson, Dr. Tommy Wood, Mark Manson, Katy Bowman, Gabby Reece, Cynthia Thurlow, and Melanie Avalon.
