The B.rad Podcast

What if running one lap around the track could reveal more about your longevity potential than any other fitness test?
The 400-meter run is known in track and field as the “race of truth,” challenging your fast-twitch and slow-twitch muscle fibers, aerobic and anaerobic energy systems, and your ability to maintain your technique as fatigue sets in. I revere it as the single best longevity marker known.
In this episode, I explain why mainstream fitness programming emphasizes aerobic conditioning while often neglecting the speed, power, and explosiveness that decline much more rapidly with age.
I also discuss research linking mile-run performance at age 50 with the potential to reach 80 in good health, and share my age-graded 400-meter chart, which lets you compare your time with performance standards for your age, all the way to 100.

TIMESTAMPS:
The nickname for the 400 meter run is the Race of Truth. That is one lap around the typical track. [01:01]
For the first seven seonds you are running on stored phosphocreatine which is the energy stored directly inside the muscle cell that exhausts quickly. [03;24]
Thje enxt phase is called anaerobic glycolysis that is burning sugar glycolysis without oxygen. [04:27]
The 400 is an all out examination for all the energy systems, not just a very narrow sliver of your fitness capabilities [07:50]
Humans are the greateast endurance creatures on earth. [10:24]
Brad contends that tracking your performance in the 400 meters reveals more about fitness and longevity potential than any other fitness or even medical marker. [11:17]
Brad explains how to analyze your performance on the chart on his website: "Age-Graded Longevity Performance Standards" [13:30]
One can expect about a 6% decline per decade. [18:12]

It’s time for some more Bradsplaining!
These are short episodes inspired by longer, full-length episodes that I have on the B.rad Podcast, so if you want a little quick hit, maybe it will interest and intrigue you to listen to a longer show on the same subject—that’s the idea.
In this episode, I’m talking about sleep and why it comes first on the list of health objectives—everything else flows downstream from getting optimal sleep. That’s nothing new or revelatory, but I see a lot of people paying lip service to the importance of sleep, and then these habits leak into the picture, especially when it comes to interacting with screen technology as the evening comes to an end.
In this show, you will hear about how you can easily create a nice transition from a waking state to a good night’s sleep, why I’ve found that I need about nine hours a night, and the simple habits that can help you awaken refreshed and energized in the morning.
From minimizing artificial light and digital stimulation to keeping your bedroom cool and getting direct morning light, these are some of the strategies that can help you put your sleep habits first and set yourself up for a good night’s sleep.

TIMESTAMPS:
Getting optimal sleep is the number one objective you should have for health and longevity goals. People differ in what their body requires of sleep. [01:14]
You want to wake up in the morning feeling refreshed and energized. It starts with sensible evening habits that help set up that transition to you sleep environment. [04:06]
Red light ambience in your bedroom is so much better than the white light color you get from light bulbs or the blue from screen. [06:15]
Try taking an evening walk before bed or acquire a cooling mattress. Your body likes to be cool before sleep. [07:54]
Our digestive circadian rhythm gets thrown off if we eat too close to bed time. [09:35]
Your bedroom should be stress free. No work desk piled with "to do" jobs. TV should be enjoyed elsewhere in the house, not the bedroom. [10:53]
It is important to sleep in a cool room, keeping cozy warm with pajamas or blankets. [12:53]
Align you circadian rhythm by waking at sunrise. [18:20]

Welcome to a new series on the B.rad Podcast called “Bradsplaining,” where I provide tips, insights, and commentary on distinct subjects, giving you shorter episodes with actionable insights and takeaways.
The first episode explains why I quit jogging after 40 years—and why you might want to, too.
I was an extreme endurance machine from ages 15 to 55, but today I am a sprinter and a high jumper in the 60+ age division of Masters Track & Field. This is quite an unusual athletic transformation, as I’ve gone from competing in events lasting nearly nine hours to participating in events that last just a few seconds.
As you’ll hear, I was completely immersed in the endurance training lifestyle from ages 15 to 30. I basically spent my life eating, training, and sleeping, and was actually asleep for half of my career!
In this show, I explain why I quit endurance training in the hopes that it will help broaden your perspective on what it means to be fit for life, especially if your fitness pursuits currently skew toward endurance (which is what the vast majority of fitness enthusiasts are doing). I also reveal the worst-kept secret of the mainstream fitness scene, why the vast majority of runners should not be running, the importance of rejecting the struggle-and-suffer mentality, and how to introduce true sprinting into your training.

TIMESTAMPS:
Brad explains why he quit endurance training after 40 years and maybe you should consider it. [01:01]
Chronic cardio is a pattern of steady state cardiovascular workouts that are stressful and cause injury. [06:20]
True sprinting is a very brief all out anaerobic effort using the fast twitch muscle fibers. [09:38]
It is not that easy to reject our long ingrained habit patterns and cultural programming toward the no pain, no gain philosophy. [12:51]
Move frequently at a slow pace, lift heavy things and sprint once in a while. [15:00]

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]

I made a post the other day stating that people over 50 should be banned from running marathons, and was greatly amused to see all the savage, critical comments coming back at me.
Fair points made by those of you who are thriving in the endurance community, but what I am really talking about is the inherently stressful nature of training for extreme endurance events, like marathons and IronMan. Many people can be drawn into this deeply committed community, and end up training in an inappropriate and overly stressful manner, leading to breakdown, burnout, illness, and injury. I’ve heard enough from the folks at the front of the pack with their longevity badges and chips, but what I am concerned about is the people who are burning out, even though they are engaging in well-intentioned exercise.
Furthermore, when you dedicate so much to extreme endurance training, you—by definition—are neglecting by far the most beneficial workouts for longevity: strength training and especially sprinting. What I am advocating is a broadening of your perspective of what it means to be fit for life.
I am enthusiastic about this subject because I have had an awakening of my own after having been an extreme endurance athlete, on the professional triathlon circuit decades ago, and then continuing to train like an endurance athlete in the decades that followed—only to realize that I was falling apart and getting old. I threw my back out, tore my meniscus for no reason and realized: Wait, I do not have the full body functional fitness and power, strength, and mobility that I should.
That is when I started redirecting my compass over towards sprinting and high jumping—which I found were so much more fun, rewarding, and challenging than just shuffling along towards another distance finish line.
There is a lot more out there, and if you are not a serious competitor, and just doing something because you think this is a way of staying fit and healthy, then this show will help you broaden your perspective on the safe, low impact methods to push yourself and stimulate the anaerobic system (which gets completely neglected by most forms of mainstream training).
Tune into this episode if you want to learn the essence of an efficient sprint workout, how to feel energized and invigorated instead of fatigued and depleted after workouts, and how to effectively age gracefully!

TIMESTAMPS:
Some people are staying active in their later years with well-intentioned exercise, however some are burning out by overdoing their endeavors. [02:02]
Brad is suggesting sprinting and weight training as a goal. [03:35]
Many of the exercise patterns people are doing do not build the anaerobic system. [04:25]
Sprinting involves much rest in between bursts. [06: 10]
Falling is the number one cause of death in Americans over 65. Sarcopenia (age-related muscle loss) and dynapenia (age-related loss of muscle power and explosiveness) are the conditions. [08:00]
The sprinting routine that is recommended is 8 to 15 seconds with extensive rest of a minimum of a minute. [11:55]
When you get through with exercise, you want to feel energized and invigorated instead of depleted and exhausted. [12:30]
