Today at a Glance:
Zone 2 training enhances both cognitive and metabolic health by exercising at a moderate intensity (60-70% of max heart rate), improving fat utilization and mitochondrial function.
It boosts brain health by increasing blood flow to the brain, promoting neurogenesis, and reducing inflammation through the release of protective myokines.
Regular Zone 2 workouts help maintain mental clarity, reduce stress, and support longevity, making it an ideal exercise for long-term brain and body health.
Today’s Newsletter Is Brought To You By Momentous
Despite a healthy diet, many of us still miss out on essential nutrients. I've incorporated Momentous Whey Protein into my daily regimen to boost my overall health, enhance muscle recovery, and ensure I get the necessary protein intake for optimal performance and well-being.
One of the biggest benefits of whey protein is its ability to combat age-related muscle mass and strength loss. Starting around the age of 40, individuals can lose approximately 3-5% of their muscle mass per decade, which can significantly impact strength and mobility.
By supplementing with whey protein, you can support muscle maintenance and growth, helping to preserve strength and function as you age.
The best part?
Momentous has by far the most rigorous commitment to quality, demonstrated by expert partnerships and strict third-party testing, making their products a reliable choice upheld by top athletes.

Neuro Athletes,
In a world where exercise routines can often feel overwhelming and unsustainable, I've found one form of training that not only boosts your brain health but also optimizes your longevity—Zone 2 training.
Today, I want to share my personal journey with Zone 2, how it changed my perspective on health, and why it has become my favorite exercise to recommend for both cognitive and metabolic health.
What is Zone 2 Training?
Zone 2 training refers to exercising at a moderate intensity—typically 60-70% of your maximum heart rate—where your body primarily uses fat for energy. It's a sustainable pace, often referred to as "conversational pace," and might involve activities like cycling, brisk walking, or light jogging.
The Cognitive and Longevity Connection
When I first started looking into ways to optimize brain health through exercise, Zone 2 quickly stood out. I’m a neurophysiologist, so I’m constantly searching for methods to improve cognitive function and protect the brain from decline. Here's what I found out:
Metabolic Flexibility & Brain Health:
Zone 2 training enhances your body’s ability to use fat as fuel, improving metabolic flexibility. The brain benefits from this flexibility, as better metabolic function supports mitochondrial health, which is critical for maintaining neural function and preventing cognitive decline.Improved Blood Flow to the Brain:
Exercise in Zone 2 stimulates consistent blood flow, delivering oxygen and nutrients to the brain. Studies show that increased cerebral blood flow supports neurogenesis (the creation of new brain cells) in the hippocampus, the region responsible for memory and learning. This is crucial for preventing conditions like Alzheimer's disease, where neurogenesis slows down.
Reduction in Inflammation:
Chronic inflammation is a key driver of cognitive decline and neurodegenerative diseases. Zone 2 training activates the release of myokines—proteins like irisin—from muscles, which help reduce inflammation throughout the body and brain. These myokines are like an internal defense system, protecting the brain from inflammatory damage.Boosts Fat Utilization & Mitochondrial Health:
Zone 2 training also enhances mitochondrial function, the powerhouse of your cells, and is crucial for maintaining cellular health as you age. Better mitochondrial function leads to more efficient energy use in the brain, which is directly linked to better cognitive performance and slower brain aging.
My Personal Journey with Zone 2
As an elite triathlete in my 20s, Zone 2 training was a key part of my regimen, particularly during the winter months when I focused on building a solid aerobic base. What started as a performance tool for endurance soon evolved into a deeper understanding of how it affects the brain and body on a cellular level.
Over the years, I’ve noticed that the benefits of Zone 2 go far beyond physical stamina. I experienced enhanced mental clarity, increased focus, and improved cognitive endurance. It wasn’t just about performing better in sports—it became about thinking more clearly and sustaining that mental sharpness over time.
The most powerful shift, however, came when I began recommending Zone 2 to my clients—high-performing executives and individuals at risk for neurodegenerative conditions like Alzheimer’s. The results were remarkable. Not only did they notice physical improvements, but they also experienced enhanced cognitive performance, reduced stress, and a better sense of overall well-being—all key factors in achieving longevity.
How You Can Incorporate Zone 2 Training for Longevity
If you’re looking to protect your brain and boost your metabolic health, here’s how you can get started with Zone 2 training:
Find Your Zone 2 Range:
Aim for 60-70% of your maximum heart rate. To estimate this, subtract your age from 220, then multiply by 0.6 and 0.7 to find your target heart rate range.Exercise 3-4 Times a Week:
Keep the duration to about 30-45 minutes per session. Activities like brisk walking, cycling, or swimming are great options.Track Progress:
Use wearable tech (like a heart rate monitor) to ensure you’re staying in the right zone. Consistency is key here—you’re building long-term benefits, not chasing quick results.Incorporate It Into Your Routine:
Zone 2 doesn’t need to be a strenuous workout. You can fit it into your day with simple activities like a morning walk or cycling to work.
The Takeaway
Zone 2 training is more than just an exercise routine—it's a long-term strategy for protecting your brain, optimizing metabolic health, and ensuring you maintain your cognitive edge as you age. For me, it’s become a cornerstone of how I take care of my own health and the health of my clients.
If you’re serious about your longevity and mental performance, consider giving Zone 2 a try.
Your brain—and your future self—will thank you.
Stay healthy,

Love zone 2 training! I covered this recently in a post and shared why it’s so beneficial for sustainable fitness. I wish more people knew about it and would stop pushing themselves too hard with HIIT.
