The First Principles of Health and Fitness
From Director of Health Alex Maples
You’re busy. You’ve spent a lifetime dialing in where and how to spend your time, effort, and resources to get the best results – in your business, with your investments, with your family, and, perhaps, in your fitness journey. But, dial in prematurely and you may find that you’ve focused on the wrong tree – when the forest is somewhere else entirely.
Welcome to First Principles, a series of posts and resources to help you focus on what truly moves the needle – so the energy you spend improving your health is as efficient and effective as possible.
We’ll dive into four main pillars – those foundations that provide the greatest return on our investment when it comes to building lasting health. Here’s the quick overview:
1. Body Composition: What You’re Made Of Matters
Most people have heard about body composition, and the benefits of improving it. (Look better? Check. Be healthier? Double check.)
It’s worth noting that your ratio of muscle to fat isn’t just about aesthetics or a standalone marker of “health” – it’s metabolic currency. More muscle improves insulin sensitivity, bone density, and resting metabolic rate. Too much fat, especially around your organs (visceral fat), drives inflammation and increases the risk for chronic disease. Improving lean mass while reducing fat is strongly associated with lower all-cause mortality.
Think of your body like a financial account: Muscle is your investment, fat is your overhead. The goal is to build the account wisely. Muscle is a long-term asset – it keeps us strong, mobile, and resilient as we age. Unfortunately, muscle loss is inevitable with aging. But the more muscle we invest in building during our prime years, the more we’ll retain later in life, helping us stay upright and independent.
Fat, on the other hand, is the cost of doing business. Sometimes it accumulates as a byproduct of growth. That’s okay – it's part of the process. But eventually, the books need to be balanced. That’s where fat loss phases come in. They’re our financial audits – strategic, intentional efforts to trim the excess and keep our health account in the black.
2. Cardiorespiratory Fitness: The Engine Under the Hood
Often relegated to the realm of the endurance sports nuts, cardiorespiratory fitness (CRF) is in fact one of the strongest predictors of lifespan. VO₂ max, a key measure of CRF, reflects how well your body delivers and uses oxygen – a fundamental requirement for every cell in your body.
Good CRF helps you think clearly, recover faster, and handle more physical and mental stress. It lowers the risk of heart disease, stroke, and even some cancers. (And, yes, it lets you run that ultra if you want to.)
The best part? You don’t need to run marathons. Consistent zone 2 cardio (think brisk walking, cycling, rowing), along with occasional higher-intensity sessions, can make a profound difference.
3. Sleep and Recovery: Your Built-in Repair System
If you’ve tried to get healthier, your first instinct (like many people’s) might be to add more: more workouts, more supplements, more productivity hacks. But sometimes the most powerful lever is knowing when to rest.
Without quality sleep and recovery, you don’t adapt – you just accumulate stress. Recovery is when your body rebuilds, your hormones rebalance, and your mind processes the world around you.
Lack of sleep impairs glucose metabolism, weakens the immune system, disrupts mood, and fogs cognitive function. Deep sleep, in particular, is essential for physical restoration.
When you train, you write the check. Recovery is when you cash it.
4. Stress Management and Purpose: The Psychological Core
You can’t out-lift chronic stress or out-supplement a lack of meaning. (Read that again.)
Stress isn’t inherently bad – if you have goals or care about anything (i.e., you’re human), stress comes with the territory. In fact, too little stress can be just as dangerous, often signaling a lack of purpose or engagement.
The real key is learning to manage and channel it. Chronic stress disrupts your hormones, appetite, sleep, and focus. But when stress is anchored to purpose, it becomes fuel instead of friction.
A clear why is a GPS for your nervous system. It helps you reframe discomfort as growth, and it keeps you aligned when life gets messy.
We build resilience just like we build strength: through consistent training. Breathwork, boundaries, meaningful relationships, movement, time in nature – these are essential tools, not luxuries.
It’s a System, Not a Checklist
These four pillars don’t exist in isolation – they support and amplify one another. Better sleep enhances body composition. Cardio improves stress tolerance. Purpose sustains consistency.
Health isn’t about chasing perfection — it’s about mastering the fundamentals and building a system that works for your real life.
This series is designed to equip you with practical tools and mental models to strengthen the core pillars of health. You’ll learn how to filter out the noise, focus on what actually matters, and tailor a system that fits your goals and lifestyle. Whether you want a quick overview or a deep dive, you’ll find both the why and the how, along with a clear roadmap to support not just your health, but your life as a whole.
