A grandfather bends down to pick up a toy without grimacing. An 80-year-old neighbor climbs the stairs with a grocery bag as if she were 40. That day, in a rehabilitation room in Boston, a gerontologist was quietly observing patients over 70. Some were walking on a treadmill, others were pedaling slowly. And at the back of the room, a 76-year-old woman kept standing up from a chair—again and again—without stopping.
The doctor smiled, almost amused. He didn’t take notes on the treadmill or the bike, but on that precise movement: standing up, sitting down, repeating. Nothing spectacular. No music, no technology, no visible strain. Just a movement the body has known forever, but practices less and less with age.
Later, in the hallway, he made a remark that became famous among his students: “Walking is good. But this is what keeps people independent.” He was referring to that simple, repetitive movement that gerontologists now consider a quiet pillar of healthspan after 70.
The Movement Pattern Gerontologists Emphasize
Ask ten people over 70 how they stay fit, and most will mention walking, sometimes gentle exercise classes. Yet gerontologists who study falls, fractures, and loss of independence point to another key indicator: the ability to stand up and sit down, again and again.

This sequence—sitting, standing, bending, reaching, lowering, rising—separates a fragile body from a resilient one. It isn’t glamorous, but it perfectly matches what daily life demands: picking up keys, gardening, playing on the floor with a grandchild, getting up at night to use the bathroom.
Researchers refer to these as “transitional movements”: moving from lying to sitting, sitting to standing, standing to walking, and back again. The data are clear: the easier and more frequent these transitions are after 70, the lower the risk of severe disability, hospitalization, and loss of independence. Walking supports the heart. Transitions support daily life.
What Simple Clinical Tests Reveal
In Brazil, a striking study used a surprisingly simple test: sitting down on the floor and standing back up without using hands or knees. Participants who struggled had a higher risk of mortality in the following years. It wasn’t an athletic challenge—it was a window into real-world mobility.
In Europe and the United States, similar chair-based tests are used: how many times can a 75-year-old stand up and sit down in 30 seconds without using their arms? These numbers predict far more than leg strength—falls, independence at home, recovery after surgery. The sit-to-stand test often reveals more than a step counter on an app.
Margaret, 79, in Manchester, walked every day around the same block. She thought she was doing everything right. After a fall in her kitchen, she realized she couldn’t get up on her own. Her geriatrician didn’t prescribe a treadmill, but a floor and a mat. For months, she simply practiced getting down and standing back up safely. Today she still walks, but what reassures her most is knowing she can get back up if she slips.
Why These Movements Are So Powerful After 70
Standing up and lowering down engage the entire system: muscles, joints, balance, brain, and circulation. Standing challenges the legs and heart. Lowering with control demands stability, coordination, and core engagement. No sophisticated machine can fully replicate this complexity.
Walking is linear and predictable. Transitions are three-dimensional and rooted in real life: bending, rotating, reaching sideways. When these patterns disappear, the body doesn’t just grow weaker—everyday tasks turn into obstacles, and healthspan quietly shrinks.
There’s also a psychological component. Those who maintain these transitions retain motor confidence. They dare to kneel, sit on the floor, travel, accept invitations. Avoiding these movements “to be safe” does the opposite—it reinforces fear and gradually shrinks the world around them.
How to Train the Movement That Protects Healthspan
Gerontologists agree on a simple recommendation: deliberately practice rising and lowering movements for a few minutes, several times a week. The basic exercise is the sit-to-stand from a stable chair: feet firmly planted, arms crossed or lightly resting on the thighs, stand up with control, then sit down slowly.
Once comfortable, the pattern can expand: moving from bed to sitting, then standing; kneeling on a cushion; sitting on the floor; then rising step by step. Done mindfully, this becomes a full functional ladder, focused on familiarity rather than performance.
For some, the starting point is very modest: holding a table, lifting the hips slightly, then sitting back down. For others, it evolves into full floor rises, using hands if needed. The principle remains the same: moving through levels, not just forward in a straight line.
Let’s be honest—few people do this daily. The trick is to weave it into everyday life: five stand-ups before each meal, a few extra repetitions during bathroom visits, or during TV commercial breaks.
If going down to the floor feels scary, that’s not failure—it’s information. Start higher. Use a bed or sturdy chair as support. As ability improves, fear recedes, and movements once considered risky become ordinary again.
Waiting to be “fitter” is the most common mistake. The transition itself creates fitness. The goal isn’t achievement, but kind repetition. After 70, muscles still respond—just more slowly.
Rethinking How We View Aging
When gerontologists say these movements support healthspan better than walking alone, they’re inviting a shift in perspective. Healthy aging isn’t just about distance covered, but about the ability to move between levels.
Many families discover too late that a parent who “walked every day” can no longer stand up alone after hospitalization. Sharing this reality earlier turns ordinary gestures—standing, sitting, bending—into daily investments.
There’s also a social dimension. These exercises can become shared moments: a game with a grandchild, a weekly routine with neighbors. That makes training more human and less medical.
Finally, there’s an emotional resonance. Standing up physically mirrors the ability to rise after hardship. For some, reclaiming this movement opens doors again: traveling, moving homes, starting a hobby, sometimes even a new relationship.
After 70, the future isn’t written only in medical records. It hides in how a person sits, stands, or reacts when something falls to the floor. These micro-moments contain powerful clues about tomorrow’s independence.
Key Takeaways
Transitional movements: Regularly practicing sit-to-stand and floor-to-stand movements predicts independence better than step counts.
At-home practice: Chair rises, bed-to-chair transitions, and gradual floor work, two to three times per week, with no equipment.
Healthspan mindset: Shift from “how much I walk” to “how easily I change levels” for more meaningful goals after 70.
