The Movement Doctor

Your body is the only home you’ll ever own.

You can’t sell it.
You can’t move out.
You can’t trade it in.

So treat it like somewhere you actually want to live.

Getting in shape is not just a physical process.
It is a spiritual process disguised as a physical one.

It requires discipline when comfort calls.
Consistency when motivation disappears.
Humility when your body tells the truth.
Patience when results take time.
And faith to keep showing up before anything changes.

Your body is not just something to look at.
It is something you’ve been entrusted to steward.

Train it.
Fuel it.
Respect it.
Heal it.
Move it.

Because transformation does not start in the mirror.
It starts in the heart.

Concentric or eccentric training?

Maybe the better question is: do coaches actually understand that muscles almost never function as purely concentric or purely eccentric in real movement?

In the weight room, those terms are useful for teaching tempo or describing a lift. But in authentic movement, tissue has a three-dimensional responsibility. A muscle can be lengthening in one plane, shortening in another, and stabilizing or decelerating in a third — all at the same time.

That is why the Gray Institute concept of econcentric function matters.

The body does not think, “I’m doing an eccentric rep now.” It reacts to gravity, ground reaction force, momentum, mass, and task demand. Muscles are turned on by motion. They load to explode. They decelerate one segment to accelerate another. That happens through the whole chain, not in isolated muscle actions.

So when coaches only chase “eccentric training” or “concentric power,” they may be missing the bigger truth:

The body trains in transformational zones, not textbook contractions.

A lunge, cut, throw, jump, sprint, or change of direction is not simply eccentric then concentric. It is tri-plane loading and unloading. The tissue is constantly managing sagittal, frontal, and transverse plane motion simultaneously.

So yes, eccentric and concentric language has value. But if a coach does not understand econcentric, chain-reactive, task-specific function, they are probably training muscles more like parts on a machine than tissues inside a living, reacting human being.

🦴 Educational Moment: Could the Calcaneus Be the Most Important Bone in the Body?

Fun question.

Most people call it the heel bone.

But in 3D function, the calcaneus is much more than that.

It is one of the body’s most powerful chain-reaction drivers.

Every time your foot hits the ground, the calcaneus helps decide what happens next:

✅ Does the foot load properly?
✅ Does the arch respond?
✅ Does the tibia rotate?
✅ Does the knee track well?
✅ Does the hip receive the right motion?
✅ Does the pelvis and spine get the right message?

When the calcaneus everts, it helps create pronation, unlocks the midfoot, and drives internal rotation up the chain.

When it later inverts, it helps create a stable foot for propulsion.

So no, the calcaneus does not work alone.

But it may be one of the most important “conversation starters” in the body.

Because the ground speaks first through the foot.

And the calcaneus is one of the first bones to listen.

Pain in the knee, hip, low back, or even higher up the chain?

Do not forget to ask:

What is the calcaneus doing?

The body is not a collection of isolated parts.

It is a 3D chain reaction.
