The truth about VO2 Max: What it really says about your health & Longevity
The Fitness Number That Matters, but Not as Much as You Think
For years, VO₂ max was treated as the “golden marker” of fitness and performance. Scientists, coaches, and athletes believed the higher your VO₂ max, the better you’d be. But reality, and life experience, tell us a different story.
What Is VO₂ Max?
VO₂ max is the maximum amount of oxygen your body can use during exercise.
Think of it as the size of your engine, your body’s capacity to take in, transport, and use oxygen for energy.
But here’s the catch: performance is not only about the size of the engine.
The Real Game Changers
Studies, including research on Kenyan marathon champions, show that the winners aren’t necessarily those with the highest VO₂ max. What sets them apart are:
Efficiency
– using less energy with every stride.
Lactate threshold
– pushing fatigue further away.
CO₂ tolerance
– handling the buildup of gases without panicking.
In other words, it’s not just how big your engine is, but how smartly you use it.
vVO₂ max vs. Vmax – Clearing the Confusion
vVO₂ max
(Velocity at VO₂ max): The slowest speed at which you reach your maximum oxygen uptake.
If you go any slower, you won’t reach VO₂ max.
Vmax
(Maximal Aerobic Velocity): The fastest pace you can sustain while at VO₂ max.
(PS: Some coaches use “Vmax” to mean the fastest pace you can sustain at VO₂ max. In most laboratory studies, however, the preferred term is Tlim @ vVO₂ max.)
Tlim @ vVO₂ max:
The time limit you can maintain vVO₂ max before exhaustion, essentially, how long you can stay in the VO₂ max zone.
Think of a car:
VO₂ max = engine size
vVO₂ max = the speed where the engine first hits the redline
Vmax or ( Tlim @ vVo2 max ) = the top speed you can keep while staying in the red zone
Training With VO₂ Max in Mind
The popular 4×4 method (run 4 minutes at high effort, recover 3, repeat 4 times) is one way to boost VO₂ max.
But here’s the truth: it’s not a “one-size-fits-all.”
You don’t need a lab test to know your limits.
Running by feeling — where you’re challenged but not collapsing — can be just as effective.
Do You Really Need to Worry About It?
Not unless you’re competing.
The healthiest people I’ve met, including my 99-year-old grandmother, never thought about VO₂ max.
They stayed active daily, walked, climbed stairs, ate simple unprocessed food, laughed often, and lived with purpose.
Longevity is more about consistent movement, community, and joy than chasing a number.
Bottom line:
VO₂ max is important, but it doesn’t define you. Move often, breathe deeply, and enjoy life. That’s the real secret.

Why drinking more water doesn’t always mean better hydration Most people believe that the more water they drink, the more hydrated they become. In reality, hydration is less about quantity and more about how well your body absorbs and uses water. Your body processes water gradually. Drinking large amounts at once often means the excess is quickly eliminated through urine, sometimes along with valuable minerals needed for fluid balance. This is why many people drink plenty of water and still experience signs of dehydration. The principle is similar to breathing: more isn’t always better. You don’t oxygenate your body by taking huge breaths, what matters is efficient exchange in the lungs. Hydration works the same way: steady, efficient absorption matters more than excess intake. Drink smarter Sip small amounts regularly throughout the day Start the morning with room-temperature water Avoid chugging large quantities all at once Support hydration with natural minerals and electrolytes Why temperature matters Ice-cold water may feel refreshing, but it’s not always ideal for digestion. Your stomach and intestines rely on smooth rhythmic contractions — Peristalsis — to move food and fluids efficiently. Very cold water can temporarily tighten these muscles and, in sensitive people, create heaviness, cramping, or digestive discomfort. ( If your kids are complaining about stomach pain, look at what they are dinking to rehydrate...) Your body also needs to warm very cold water before efficiently processing it, so this is a waste of energy. It is tiring your body unnecessarily. Room-temperature or slightly warm water is often easier on the body and gentler on digestion. Timing matters When you drink matters too. Hydrating between meals is often ideal. Drinking large amounts during meals may reduce the quality of your digestion by diluting gastric contents, which can make digestion feel heavier. A simple rhythm: Drink regularly through the day Hydrate before meals Resume after eating Avoid waiting until intense thirst appears When dehydration quietly happens Remember, you lose water constantly, often without noticing, especially: After sleep After exercise Sauna / heat exposure Alcohol High sugar intake Chronic stress Mouth breathers, or if you speak for hours ( teachers..) Long sun exposure Dry wind (which increases evaporation and respiratory water loss) Hydration should be continuous, not occasional. My personal hydration ritual I carry my water bottle with me everywhere. It has become part of my rhythm, not because I force myself, but because I know the body thrives on steady hydration. I often enrich my water naturally with: Fresh lemon A tiny pinch of mineral-rich salt Cucumber, mint, ginger a nd other natural blends I personally use, I’ll share the link on our what'sapp community I also like to drink coconut water as it hydrates very well the body For me, water is not just something to drink. It is daily nourishment for every cell in the body. Hydration is not about drinking more It’s about drinking better:
right amount, right timing, right temperature, right balance.
Have you ever noticed how your pain follows your life more than your posture? A back that locks just before a difficult conversation. A migraine that shows up every Sunday evening. Shoulders that feel light and free on holiday… then tighten the moment you return home. This is not random a nd it is not “just in your head.” It is your nervous system responding to your environment. The Geography of Stress In practice, I’ve seen this pattern again and again: Pain that moves. Pain that flares without clear injury. Pain that disappears when life feels lighter. We often call this psychosomatic pain, but that term is misunderstood. The pain is real, t he biology is real, t he experience is real. What changes is not the truth of the pain but where it comes from. It is no longer just about tissues or structure. It becomes an interaction between your nervous system, your emotional load, and your physical body. Biology, Not Imagination Stress is not abstract. It is physical. When your brain perceives pressure whether it’s a deadline, tension at home, or something you are trying to avoid, it activates your sympathetic nervous system. And the body responds immediately: • Cortisol and adrenaline rise • Muscles tighten, preparing for action • Heart rate increases • Recovery and repair are pushed aside This response is designed to protect you. But when it becomes constant … it starts to wear you down. The body never fully switches off. Muscles stay slightly contracted. Inflammation increases. Pain sensitivity rises. What began as protection slowly becomes burden. Why You Feel It in Your Joints Many people say, “stress goes into my joints.” Not exactly. Tension begins in the nervous system. It expresses through the muscles. But the joints… are where you feel it the most. Why? Because muscles control how your joints move. When muscles stay tight: Movement becomes restricted, j oint lubrication decreases, l oad is no longer evenly distributed And this creates a loop: Stress → Tension → Restricted Movement → Joint Stiffness → Pain → More Stress A perfect cycle. The Hips Don’t Lie At the center of your body is a deep, powerful muscle: the psoas. It connects your spine to your legs and i t reacts instantly to stress. You may have heard that the psoas “stores emotions.” The truth is that it does respond to them, fast. If your system is constantly on alert, your psoas stays engaged. Your hips tighten, y our posture shifts, y our lower back begins to compensate. Over time, this becomes discomfort… then pain. The Ones Who Carry the Most There is a pattern I see often. The caregivers. The ones who hold everything together. The ones who don’t stop. They take on more. They give more. They ignore their own signals. Until the body stops whispering… and starts shouting. If you see yourself here, understand this: Your pain is not weakness, i t is the result of staying “on” for too long. A Different Way to Look at Healing Pain is not always damage, s ometimes, it is a message. A reflection of how your body, your mind, and your environment are interacting. Healing, then, is not only about fixing tissue. It is about: • Reducing the load you are carrying • Restoring movement where things feel stuck, most of the chronic pain and excessive stiffness in your body are due to tension you are holding for too long • Becoming aware of what your body has been holding Your body is not against you, It is adapting. Trying to protect you in the only way it knows how. Small changes, done consistently, can completely change how your body feels.
