Born to Squat, Built to Hinge

Watch a toddler pick something up off the floor. They don't bend over and round their back. They drop into a flawless deep squat — heels down, chest tall, hips below their knees — hang out there like it's nothing, grab the toy, and stand back up. Nobody taught them that. It's factory settings.

Now watch the average adult pick up a dropped phone. Stiff-legged hinge at the waist, knees locked, one hamstring screaming, a little grunt on the way up.

Somewhere between the sandbox and the office chair, we traded away a movement we were born with. And here's the part most training programs get backwards: the squat and the hinge are not the same problem. One is a pattern you have to build. The other is a pattern you were given for free — and only have to keep.

The hinge: the pattern you build

The hip hinge — hips driving back, spine staying long, hamstrings and glutes loading like a drawn bow — is the most valuable strength pattern in the human catalog. It's how you pick up anything heavy without sacrificing your back. It's where jumping, sprinting, and throwing come from. It's the deadlift, the kettlebell swing, and every athletic movement that ever made a highlight reel.

But unlike the squat, nobody is born with a loaded hinge. It has to be earned under progressively heavier weight, because its payoff — posterior-chain strength and power — is exactly what modern life never asks of you and aging most aggressively takes away. Research on aging consistently shows power (how fast you can produce force) declines nearly twice as fast as strength. Power is what catches you when you trip. It's the difference between a stumble and a hip fracture.

That's why the hinge is the backbone of how I program: kettlebell deadlifts to groove it, heavier pulls to strengthen it, and swings to make it fast. A heavy kettlebell swing is a power practice you can keep until you're 90 — and it might be the single best insurance policy you can buy for the second half of your life.

The squat: the pattern you keep (or lose)

The deep squat is different. It isn't primarily a strength expression — it's a mobility and stability audit. Sitting in the bottom of a squat requires your ankles to dorsiflex fully, your hips to flex and rotate, your t-spine to extend, and your core to organize all of it at once. That's why the deep squat is the first pattern on the Functional Movement Screen: it tells on every joint in the chain at the same time.

You don't need to load it heavy. You need to not lose it. And we are losing it, on an industrial scale.

The mobility program that plumbing canceled

Here's a fun piece of history: for roughly the entire existence of our species, every human being performed a full-depth squat multiple times a day, every single day, for their whole life — because that's how you go to the bathroom when there's no toilet. The sitting toilet is barely 150 years old as a mass phenomenon. Before that, the deep squat wasn't an exercise. It was non-negotiable daily maintenance, several minutes a day, from toddlerhood to old age.

Think about what that schedule looks like as a mobility program: full ankle dorsiflexion, full hip flexion, a decompressed spine, held for minutes, daily, forever. No coach, no app, perfect compliance. Then plumbing showed up and quietly deleted the most consistent mobility practice in human history — and replaced it with a chair-shaped day: chair for breakfast, chair for the commute, chair for work, couch for the evening, throne for everything else.

Your ankles didn't stiffen because you got old. They stiffened because nothing in your day ever asks them for range anymore.

What the "unbroken" movers can still do

Look at populations whose daily lives never industrialized — the Hadza of Tanzania are the best-studied example — and you see something striking. Adults deep into their 60s and 70s rest comfortably in a full squat. Not as a party trick: as furniture. Researchers studying the Hadza found they're "sedentary" about as many hours a day as Americans — but they spend those hours squatting and kneeling, positions that keep muscles lightly working and joints moving through full range, instead of collapsed into chairs.

And their movement diet is diverse in a way no gym membership replicates: walking miles on uneven ground, climbing for honey, carrying water and firewood (the original farmer carry), digging, crawling, balancing, running, jumping. No sets and reps — just an environment that demands the full human movement vocabulary every day. The result is what movement screens dream about: old adults who can still get to the floor and back up without using their hands.

That last skill matters more than it sounds. A well-known Brazilian study had adults simply sit down on the floor and stand back up, scoring them on how little support they needed. The score predicted all-cause mortality better than almost anything that simple has a right to. Losing the floor is losing years.

Build the hinge. Keep the squat. Feed the animal.

So the prescription writes itself, and it's refreshingly simple:

1. Build your hinge like it's your job. Kettlebell deadlift to learn it. Progressive loading to strengthen it. Swings to make it powerful. Two or three sessions a week of hinging covers the pattern modern life never trains and aging attacks first.

2. Keep your squat like it's your birthright. Accumulate time in the bottom position — I like the prying goblet squat: a light kettlebell held at the chest as a counterbalance, sink to full depth, and gently shift, rock, and breathe down there for five slow breaths. A few minutes a day of bottom-position time is you re-subscribing to the program your plumbing canceled. Sit on the floor while you watch TV. Get down there and back up more often, just because.

3. Feed the animal some variety. Crawl during your warm-up. Balance on something. Carry heavy things for distance. Climb when life offers you the chance. You don't need to cosplay a hunter-gatherer — you need to give your joints a reason to keep their range and your nervous system a reason to keep its options.

You'll never need to squat 400 pounds, and you'll never be asked to. But the ability to rest at the bottom of a squat, and the power to hinge hard when life demands it — those two things are the difference between getting old and getting fragile. One you build. One you keep. We're not going for perfect, just better — and both of these get better fast.

The tools for both live in the same place: a kettlebell for the hinge, and the same kettlebell held at your chest for the squat you're taking back.
