Training for Life, Pt. II: How Functional Movement Protects Your Longevity

The Art of Scaling in Action

Imagine standing at the base of a beautiful mountain trail. What happens when the steepening incline begins to feel challenging? You review your options to ease the intensity. Perhaps you adjust your pace and hike slower. Or maybe you shorten your gait. Perhaps you take out your trekking poles to utilize your arm muscles.

This is scaling in action. It’s the art of adapting the challenge to match your current capacity while keeping your body engaged in the activity.

In the last article, we looked at how my dad maintained his independence to age 101 by holding fast to an identity of movement. But maintaining that identity requires a practical toolkit.

To keep your physical freedom intact, you don't need to train as intensely as a competitive athlete. You simply need to keep your body's natural capabilities in good working order to support the life you want to live.

World-Class Fitness in 100 Words

In Part I, I mentioned that CrossFit distills broad-based fitness into a famous 100-word definition. Here it is in full:

Eat meat and vegetables, nuts and seeds, some fruit, little starch and no sugar. Keep intake to levels that will support exercise but not body fat. Practice and train major lifts: Deadlift, clean, squat, presses, clean & jerk, and snatch. Similarly, master gymnastics basics: pull-ups, dips, rope climb, push-ups, sit-ups, presses to handstand, pirouettes, flips, splits, and holds. Bike, run, swim, row, etc, hard and fast. Five or six days per week mix these elements in as many combinations and patterns as creativity will allow. Routine is the enemy. Keep workouts short and intense. Regularly learn and play new sports.

While words like handstands, snatches or flips can sound extreme at first glance, the underlying takeaway is deeply liberating: Your body was designed to be adaptable. You aren't meant to sit in static positions all day. You are meant to lift, carry, bend, run, balance and explore.

Your Physical Toolkit: The 10 General Physical Competencies

When my dad navigated his nineties with such grace, it was because his physical toolkit wasn't missing any essential pieces. True fitness isn't just about how far you can walk or how much weight you can carry; it’s a balanced combination of 10 distinct competencies that work together to protect your independence:

Organic Adaptation (Built through physical practice):

Cardiovascular/Respiratory Endurance: Your engine’s ability to gather and deliver oxygen (e.g., climbing a steep set of stairs).
Stamina: Your muscles' ability to process and utilize energy (e.g., spending an entire afternoon exploring a new city on foot).
Strength: The ability of a muscle to apply force (e.g., lifting heavy luggage or bags of mulch).
Flexibility: Maximizing your range of motion across your joints (e.g., bending down easily to tie your shoes or reach under a bed).

Neurological Adaptation (Built through mental focus and coordination):

Coordination: Combining several distinct movement patterns into a singular rhythm (e.g., walking on uneven surfaces).
Agility: Minimizing transition time from one movement pattern to another (e.g., stepping quickly out of the way on a busy sidewalk).
Balance: Controlling your center of gravity relative to your base (e.g., standing safely on one foot or washing your hair with your eyes closed).
Accuracy: The ability to control movement in a given direction or at a given intensity (e.g., stepping precisely onto a narrow curb or dispensing medicine).

The Bridge (Requires both organic and neurological adaptation):

Power: The ability to apply maximum force in minimum time (e.g., hitting the brake pedal quickly in an emergency or pushing yourself up from the floor).
Speed: The ability to minimize the time cycle of a repeated movement (e.g., re-establishing your footing during a slip or stumble).

If you only walk on flat, even pavement, you’re training endurance, but you may be losing agility, balance, power and coordination – the very skills that prevent a fall when you step on an unexpected patch of ice or an uneven curb. A resilient buffer requires keeping all 10 tools sharp.

Fueling the Engine: Your 3 Energy Systems

To keep your physical toolkit functional, your body relies on three distinct energy systems (metabolic pathways):

Burst Power (The Phosphagen Pathway): High-power energy that lasts 5–10 seconds. This is the immediate power you use to catch yourself from a stumble or lift something heavy suddenly.
Sustained Effort (The Glycolytic Pathway): Moderate-power energy that lasts up to a few minutes. This is the energy used for climbing a steep hill or carrying heavy groceries up a flight of stairs.
Cruise Control (The Oxidative Pathway): Low-power, long-duration aerobic energy that lasts for hours. This type of energy powers long walks, daily errands and scenic hikes.

Standard midlife wellness advice often focuses almost exclusively on the third pathway – steady, low-intensity aerobic activity. While aerobic health is vital, neglecting the first two pathways contributes to the gradual loss of muscle mass, fast-twitch muscle fibers and bone density as we age.

Including short, intentional bursts of higher intensity in your routine supports your muscles, bones and keeps your metabolic engine firing on all cylinders.

Designing Your Simple Longevity Plan

If reading through all of these definitions, pathways and competencies feels a bit overwhelming, take a deep breath.

You don’t need to become a CrossFit athlete, buy expensive equipment, or memorize metabolic pathways to start building your wellness buffer. The beauty of functional movement is that it isn't an all-or-nothing proposition, it’s about slow, methodical progress.

Building an enduring identity of movement is about curiosity and consistency. Here’s how you can begin exactly where you are today and create a simple, approachable plan:

1. Pick one competency to practice. Choose one tool from the 10 competencies to mindfully focus on this week. For example:

Strength: The next time you sit down in a chair, pause for two seconds right before your body touches the seat, then stand back up. You’ve just practiced a scaled squat. Keep your shoulders back and focus on lowering your body with control.
Balance: Practice standing on one foot for 15 seconds at time while going about your routine, such as brushing your teeth or waiting for your morning coffee to brew.
Power: During your next walk, find a short hill or a stretch of trail to pick up your pace for 10 seconds before returning to your normal stride. Repeat periodically throughout your walk

2. Prioritize Mechanics Over Intensity. Always focus on technique, mastering the correct movement pattern before adding weight, speed or duration. Honor where your body is today. A light, perfectly executed movement builds far more headroom than a heavy, rushed one with incorrect form.

3. Redefine Your Movement Identity.Above all, listen to your self-talk. Be mindful of viewing yourself as an aging body trying to manage decline. Begin to see yourself, just like my dad did, as a person whose body is naturally built to balance, carry, reach and respond when called upon.

What's Next

So far in this series on longevity, we’ve explored two of three ways to build the foundation of our physical buffer: 1. Shifting from neutral wellness to active fitness; and 2. Understanding the core mechanics of functional movement.

In our next article, we’ll complete the trilogy by looking at the fuel that powers the entire system. We’ll explore nutrition not as a restrictive diet, but as clean, intentional information that controls inflammation, balances your energy, and anchors your mental and emotional resilience during life’s big transitions.

The Question to Walk With

As you move through your day or head out onto the trail, carry this question with you:

Which of the 10 physical competencies do I rely on most in my daily life? What is one small practice I can introduce today to show my body I still trust it to balance, lift, and lead the way?
