There is something satisfying about knowing what comes next. We tend to settle into familiar routes, familiar routines, even familiar places around the house. We learn which grocery store aisle has what we need and which road is usually faster at a certain time of day. After a while, we don’t have to think very much about any of it. We just move through our days.
I don’t think that’s necessarily a bad thing. Most of us have enough to think about already, and routines make life a little easier. There’s a reason we put the keys in the same place and develop our own way of getting things done. Somewhere along the way, though, I started thinking about how much of our physical lives become predictable too.
Most days, we move in ways we’ve moved thousands of times before. We get out of bed, walk through the house, get into the car, sit down, stand up, carry things and climb stairs. Even exercise can become remarkably predictable. We know where our feet are going. We know what movement comes next. If we follow a workout regularly, we may even know what Ro is about to say before she says it.
And then something doesn’t go according to plan.
Your foot catches the edge of something you didn’t see. Someone steps in front of you while you’re walking. Something slips out of your hand and, without thinking, you reach for it. A child suddenly changes direction while you’re trying to keep up. None of these moments seems particularly important. Most are over almost as quickly as they begin.
But I’ve become interested in that split second between realizing something has changed and deciding what your body is going to do about it.
Because life doesn’t always give us time to get into position first.
When the Body Has to Figure It Out
We don’t usually think about those moments as physical skills. If you catch yourself after an awkward step, you probably don’t stop afterward and congratulate yourself on your reaction time. You just keep walking. When you move quickly to avoid bumping into someone, it barely registers. The body solves the problem and the day continues.
Maybe that’s part of why these abilities are so easy to overlook. Strength is easier to recognize. We can feel when something becomes easier to lift. Endurance announces itself when we can walk farther without getting tired. Flexibility gives us fairly obvious feedback too. But the ability to adjust when something changes tends to remain invisible until the moment we need it.
I’ve spent a lot of years encouraging people to become stronger, and I still believe strength is one of the most useful things we can build. But strength doesn’t operate by itself. Real life asks us to use it while we’re turning, reaching, stepping around something, shifting our weight or realizing that where we intended to put our foot is no longer where it needs to go.
That’s a different kind of conversation with the body. Instead of saying, “Here’s the movement. Now do it,” we’re asking, “Something changed. What can you do now?”
I think we sometimes stop asking that question as we get older. Not intentionally. We simply get good at the movements our lives require most often, and naturally become less practiced at the ones they don’t. We may even start avoiding certain movements because they feel unfamiliar or because we’re no longer as confident doing them. Gradually, the world of movement can become a little smaller without us ever making a conscious decision to shrink it.
That’s what interests me more than whether any of us can move particularly fast. The goal isn’t to become the quickest person in the room. It’s to keep enough options available that when life asks us to move differently, our first thought doesn’t always have to be, I don’t do that anymore.
Agility Is Bigger Than Quick Feet
For a long time, the word agility made me think of athletes. Cones on a field. Ladders on the ground. Someone moving very quickly from one marker to another while a coach holds a stopwatch. In that setting, agility is about performance. How quickly can you react? How efficiently can you change direction? Can you get there before someone else?
Those things matter in sports. They just aren’t the only reason agility matters.
For the rest of us, there is no stopwatch. Nobody awards points because we stepped around a box in the hallway without tripping over it. We don’t get a medal for changing direction smoothly when the dog suddenly decides our walking path belongs to him. But underneath those ordinary moments are many of the same abilities: noticing what’s happening, shifting our weight, controlling our momentum and putting the next step somewhere useful.
Seen that way, agility starts to feel less like an athletic quality and more like part of being physically adaptable.
And adaptability is something I think we can underestimate because it doesn’t always look impressive. Sometimes it looks like a quick step. Sometimes it’s slowing yourself down before changing direction. Sometimes it’s realizing you’re slightly off balance and correcting before the situation becomes a bigger problem. Sometimes it’s simply feeling comfortable moving sideways, backward or diagonally instead of always moving straight ahead.
None of that requires us to pretend we’re twenty years old again. In fact, I think that misses the point completely.
Training doesn’t have to recreate the chaos of real life to help prepare us for it. We can practice changing direction in a controlled space. We can intentionally shift our weight. We can work on stopping as well as starting. We can give ourselves movements that require a little more attention than putting one foot directly in front of the other. The challenge can be appropriate to the person doing it.
What matters is that the body occasionally gets a problem whose answer isn’t completely predetermined.
There is something valuable in that little moment of uncertainty. The brain pays attention. The feet have to communicate with the rest of the body. We make an adjustment. Maybe it isn’t graceful the first time. That’s okay. We’re not performing.
We’re practicing having another option.
When Movement Becomes Play Again
There is another part of this that I’ve been thinking about, and it has less to do with how well we move than how willing we are to try.
Watch children move for a while and you’ll notice how little concern they have for efficiency. They run somewhere, stop for no apparent reason, turn around, crouch down, jump over something that could easily have been walked around, and then head in an entirely different direction. The destination seems almost secondary. Moving is part of whatever they’re doing.
Somewhere along the way, most of us become much more practical. We stop jumping over things when walking around them will do. We don’t change direction unless we have somewhere else to go. We certainly don’t shuffle sideways across the living room just to see how it feels. Our movement becomes purposeful, which makes perfect sense. But I wonder whether we lose something when movement is allowed to be useful and nothing else.
This isn’t an argument that we should all start behaving like children. My knees would probably have something to say about that. It’s more about remembering that movement can still involve curiosity.
Can I step this way comfortably? What happens if I change direction? Can I slow myself down with control? Does one side feel different from the other?
Those are simple questions, but asking them changes the experience. Instead of movement being something we’re either good or bad at, it becomes something we’re exploring. A missed step isn’t automatically failure. Sometimes it’s simply information: Well, that was harder than I expected.
I’ve seen how important that distinction can become. When someone loses confidence in a movement, the natural response is often to stop doing it. That makes sense in the short term. Avoiding something uncertain feels safer than testing it. But the less often we move in a particular way, the more unfamiliar it can feel, and that unfamiliarity can reinforce the original hesitation.
The opposite can happen too. We try something in a controlled way. We discover that we can do more than we expected. We practice it again. The movement doesn’t necessarily become spectacular, but it begins to feel more natural. And familiarity has a way of changing the conversation from I’m not sure I can do this to I know what this feels like.
Maybe that’s one of the quieter benefits of keeping some play in the way we exercise. Play gives us permission to experiment without needing every movement to prove something. There doesn’t always have to be a heavier weight, a faster time or another number to improve. Sometimes the value is simply in giving the body another experience and discovering what it can do with it.
That kind of confidence isn’t loud. Most of the time, nobody else will even notice it.
But when something unexpected happens, you might.
Preparing for Something We Can’t Predict
The tricky part about preparing for the unexpected is that we don’t actually know what we’re preparing for.
We don’t know when we’ll misjudge a step, have to move quickly out of someone’s way or reach for something before it hits the floor. We don’t know which direction we’ll need to move or how much time we’ll have to react. If we did, I suppose it wouldn’t be unexpected anymore.
That’s why I don’t think the answer is trying to anticipate every situation that might happen. We’d drive ourselves crazy, and we’d probably miss the one thing we hadn’t thought of anyway.
Maybe the better preparation is simply continuing to give ourselves options. Strength gives us options. Balance gives us options. Coordination gives us options. So does being comfortable changing direction, slowing down, shifting our weight and moving in ways that aren’t perfectly rehearsed. None of these guarantees that we’ll respond perfectly when something unexpected happens. Fitness doesn’t offer many guarantees, despite how often it’s marketed that way.
What it can give us is experience.
Our bodies remember that we’ve moved sideways before. We’ve caught our balance before. We’ve stopped our momentum and started again. We’ve had moments when our feet weren’t quite sure where they were going, figured it out and tried again. Over time, movements that once required all of our attention can begin to feel a little more familiar.
I think that’s an important distinction because preparation can easily turn into fear if we’re not careful. I don’t want to exercise because I’m afraid of everything that might eventually go wrong. I want to exercise because there are still things I want to be able to do.
That includes the predictable things: walking, carrying groceries, climbing stairs, getting up from the floor and doing the ordinary work of everyday life. But I also want enough confidence in my body that when the ordinary day changes direction, I’m ready to move with it.
Perhaps that’s what I’ve come to appreciate about agility.
It’s not really about moving fast.
It’s about remaining available to movement.
And the more I think about it, the more that feels like something worth practicing, not because we know what’s coming next, but precisely because we don’t.
I still like knowing what comes next.
I’ll probably keep taking familiar routes and putting things where I know I can find them. I’ll continue appreciating routines that make a busy day a little easier. Predictability has its place, and I don’t think there’s anything particularly enlightened about making life more complicated just for the sake of it.
But maybe our movement deserves a little less predictability than the rest of our lives.
Not chaos. Not risk. Just enough variation to remind the body that forward isn’t the only direction available. Enough opportunities to stop, turn, adjust, reach and occasionally figure something out along the way. Enough curiosity that unfamiliar movement doesn’t automatically become movement we avoid.
Because the moments we’ve been talking about aren’t really exercise moments.
They’re life moments.
Most will come and go without much thought. We’ll step around something, catch ourselves, change direction or react to whatever suddenly appeared in front of us. Nobody will know whether we handled the moment because of something we practiced months earlier. We probably won’t know either.
And maybe we don’t need to.
There are plenty of things in life worth preparing for because we know they’re coming. We save dates, make plans, set reminders and establish routines because being prepared makes life easier.
Our bodies sometimes need a different kind of preparation.
Not preparation for one particular moment, but the confidence to meet a moment we couldn’t have planned for.
We can’t practice every unexpected thing life might put in front of us.
But we can keep practicing the ability to respond.
Continue the Conversation
Think about the moments when your body has had to adjust without much warning. Maybe you caught your balance, stepped around something, changed direction, or reacted before you had time to think about it. What kinds of movement still feel natural to you, and which ones have quietly become less familiar?
Research Perspective
The larger idea behind this reflection is supported by physical-activity guidance that emphasizes more than strength or aerobic fitness alone. The National Institute on Aging notes that balance involves maintaining stability both while still and while moving, and includes examples such as walking backward or sideways. National Institute on Aging: Three Types of Exercise Can Improve Your Health and Physical Ability also recommends combining aerobic, muscle-strengthening, and balance activities as part of a well-rounded approach to healthy aging.
The Physical Activity Guidelines for Americans similarly describe multicomponent activity for older adults as potentially including balance, muscle-strengthening, aerobic activity, gait, coordination, and physical-function training. Physical Activity Guidelines for Americans, 2nd edition That broader view fits the idea explored here: useful movement is not only about producing force, but also about staying capable of adjusting when circumstances change.
Your Next Step
This week, give your body one small, controlled opportunity to solve a different movement problem. That might mean practicing a careful side step, changing direction during a walk, slowing down before turning, or noticing how your weight shifts from one foot to the other. Keep the challenge appropriate for you. The goal is not speed or performance, it is simply to stay curious and keep another movement option available.

From the Editor
I started this Journal thinking about how much of adult life is built around making things more predictable. What stayed with me while writing it was the opposite idea: confidence sometimes comes from continuing to practice what cannot be perfectly planned. We do not need to make life more complicated or turn every workout into a test. Sometimes it is enough to keep giving the body opportunities to adjust, learn, and remain available to movement.
