Reading time: 4 minutes
What I Discuss:
- How incorporating regular isometric exercises into my training routine has helped me reduce joint strain, maintain muscle strength, and bounce back quickly in new or seasonal sports…02:52
- Recent findings from the Journal of Strength and Conditioning Research investigating whether isometric exercises benefit runners—specifically repetitive, short-duration isometric squats and their impact on tendon stiffness and running efficiency…05:48
- What “running economy” means and why it’s about more than just peak fitness, plus I dispel the myth that you have to feel sore to make progress…07:44
- Why you should be mixing isometric holds, typical weightlifting (isotonics), and controlled-speed activities (isokinetics) to develop a more robust, injury-resistant, and functionally capable body…09:14
- New research suggesting that as little as ten minutes of vigorous exercise per day can deliver similar risk reduction to much longer stretches of light activity…10:04
- The greatest gains in mortality risk reduction come with about ten minutes per day of genuine, challenging exercise, debunking the “no pain, no gain” myth while encouraging attainable daily targets…13:13
- The “brain energy crisis” underlying certain forms of dementia and how both ketones and mitochondrial-targeting compounds might bypass impaired glucose uptake in the brain…16:06
- Comparing different ketone forms in terms of price, efficacy, and liver safety, and how methylene blue works at the mitochondrial level, along with important cautions…17:28
- How combining methylene blue, supplemental ketones, and near-infrared light can provide powerful support for brain function, especially under circumstances of cognitive stress, sleep deprivation, or inflammation…21:14
- Metformin and why I now favor alternatives like berberine, fiber, Ceylon cinnamon, myo-inositol, and apple cider vinegar—detailing dosages, protocols, and practical mealtime strategies…23:49
- Ideal DHT ranges, factors influencing conversion of testosterone to DHT, differences in genetics and risk for baldness, and biohacks for hair preservation…33:16
In this solosode, I kick off by talking about whether isometric training is worth your time, covering both my own fitness habits and the newest research, particularly for runners and joint health. I also unpack a buzzworthy study on how just 10 minutes of vigorous exercise daily can be a powerful longevity booster compared to longer, lighter workouts.
Additionally, you'll discover why I no longer personally use metformin and instead offer my favorite natural alternatives for better blood sugar control—like berberine, fiber, cinnamon, and simple routines like salads and walks. Plus, I get into brain health, explaining the roles of ketones, methylene blue, and near-infrared light for cognitive performance and protecting against issues like Alzheimer’s.
At the end, I answer listener questions on optimizing DHT levels, natural insulin-sensitizers, and keeping your hair healthy, even if you’re on testosterone. If you’re interested in practical strategies and exploring what’s currently working in my own routine, you’ll enjoy this episode.

Really interesting mix of fitness, longevity, and biohacking insights here. The focus on isometric training for joint health and running efficiency makes a lot of sense—especially for people who want strength without constantly beating up their joints.
The “10 minutes of real effort” takeaway is also refreshing. It lines up with what a lot of newer research is showing: consistency and intensity matter more than just long, easy sessions.
