Movement expert Kelly Starrett has a simple prescription that could dramatically improve how your body functions: get down on the ground every single day.
In a recent conversation, Starrett explained why most people’s bodies are quietly breaking down—and how a surprisingly simple daily habit can reverse the damage.
The problem isn’t just about exercise intensity or gym time.
It’s about something far more fundamental that’s been missing from modern life for generations.

The Movement Language Crisis
Starrett borrows a powerful concept from movement expert Katy Bowman to explain what’s happening to our bodies: mechanotransduction. At the cellular level, tissues need mechanical input to maintain themselves.
You want a strong tendon, how do you get a strong tendon? You have to load it right. Does it do tendon things?
He uses a striking analogy about orcas in captivity. When these powerful animals are confined to tanks, their dorsal fins begin to fold over—a condition known as folded fin syndrome. Without swimming, hunting, and the natural loading that comes from ocean life, the collagen in their fins breaks down.
Human bodies respond similarly to environmental constraints. Most people use an incredibly limited “movement vocabulary” throughout their day: sit, stand, walk slowly, repeat.
I sit, I stand, I walk very slowly, I sit, I stand, I walk very slowly. Everything is just in those few words and then I go exercise using the same words.
Even exercise often reinforces these same limited patterns—cycling on stationary bikes, using ellipticals that don’t require full hip extension. Bodies adapt brilliantly to whatever demands are placed on them, which means they’ll also adapt to limited demands.
Why Getting Off the Ground Changed Everything
Starrett points to a radical shift in human behavior over the past 10,000 years: we stopped spending time on the ground. While humans haven’t fundamentally changed physiologically, this behavioral change has had profound consequences.
Cultures where people still toilet, sleep, and sit on the ground show dramatically different health outcomes. Fall risk in elderly populations approaches zero. Hip and lower back osteoarthritis rates are significantly lower.
The reason is elegantly simple: these populations maintain exposure to full-range movements throughout their lives. Their bodies never “forget” these positions because they never stop using them.
The 20-Minute Evening Protocol
Starrett recommends spending 20 to 30 minutes each evening sitting on the ground in various positions. This isn’t structured exercise—it’s movement exposure during activities you’re already doing.
Positions to cycle through:
- Cross-legged sitting
- Squatting
- Long sit (legs extended)
- Side saddle
- 90-90 position
- Prone positions (on your belly)
The key is fidgeting and changing positions frequently. Watch television, answer emails, or listen to podcasts while accumulating this ground time.
You start to accumulate exposure which I think in my worldview is the first order of magnitude in problem solving—how do we have the human be exposed to the thing we’re trying to change or improve or restore normative ranges?
Your Body Never Stops Adapting
One of Starrett’s most important messages challenges the assumption that aging means inevitable decline. He shares a crucial insight from one of his physical therapy instructors:
Muscles and tissues are like obedient dogs. At no age do you stop adapting. At no age do you stop healing.
While adaptation may slow with age, it never stops. Simply spending time in floor positions signals your brain and tissues to maintain these ranges. Hamstrings feel better. Hips open up. The body adapts because that’s what bodies do.
The Magic of Behavior Stacking
Getting up and down off the ground adds another layer of benefit. This movement pattern—performed countless times during childhood—becomes surprisingly difficult for many adults who’ve spent years avoiding floor time.
Activities like martial arts, yoga, and Pilates require constant transitions between standing and ground positions. Starrett notes this helps explain their effectiveness—they force full-range movement patterns that modern life has eliminated.
Physician Philip Beach, in his book on functional embryology, hypothesizes that bodies tune themselves through ground contact. Kneeling, squatting, and various floor positions restore native ranges and reapproximate joints naturally.
The Sit-to-Stand Test
Starrett describes a revealing assessment: cross your feet (crisscross applesauce style), then lower yourself to the ground and stand back up without using your hands or knees.
Research suggests performance on this test predicts all-cause mortality and morbidity. But the deeper insight is what it reveals about adaptation. A skill performed hundreds of thousands of times in childhood becomes impossible for many adults.
If you’re missing some of these end ranges you’re going to struggle. It’s nice now that I have this—what’s the session cost?
This assessment becomes a vital sign, similar to blood pressure. It provides a simple checkpoint for monitoring how your body is responding to stress, environment, nutrition, and exercise.
You should be able to perform this movement with either foot crossed over the other. Having a “good side” and “bad side” indicates asymmetry that deserves attention.
No Equipment, No Excuses
The beauty of this approach is its accessibility. No gym membership required. No special equipment. No dedicated workout time carved from an already packed schedule.
For those concerned about getting down and up safely, use whatever assistance you need initially—furniture, walls, a helping hand. The practice itself will gradually restore the capacity to do it unassisted.
Additional benefits of floor time:
- Self-assessment opportunities: Notice what feels stiff or restricted
- Natural foam rolling: Keep a roller nearby for spontaneous tissue work
- Reduced barriers to movement: The floor is already there
- Integration without extra time: Movement becomes part of existing activities
Even elite athletes use this strategy. At the highest levels of performance, maintaining full range of motion requires constant attention. Ground-based movement provides that maintenance without adding another formal training session.
Your Movement Minimums
Starrett emphasizes that different activities create different adaptation demands. His example: cycling is his passion, but excessive bike time tightens his hips predictably.
Having movement assessments—like the sit-to-stand test—creates accountability. These become movement minimums that reveal how your body is truly functioning, beyond how hard you’re training or how much you’re exercising.
The distinction between movement and exercise matters. That one-hour workout, regardless of how evidence-based or perfectly programmed, represents a tiny fraction of your day. What happens during the other 23 hours?
For busy working people with limited agency over their schedules, ground time offers a practical solution. It doesn’t require motivation or willpower—just a slight shift in where you choose to sit while doing things you’re already doing.
Twenty minutes on the floor each evening. Various positions. Movement as needed. This simple practice addresses a fundamental mismatch between modern living and human design—returning a movement language that’s been missing for generations.
