You’ve seen the grandparent at the bottom of the slide, catching a three-year-old for the ninth time, still laughing, still upright, still saying again before the kid does.
You’ve also seen the one on the bench, watching from a distance, wanting to be out there but knowing they’d pay for it tomorrow.
If you want to be the first one, it isn’t about luck, and it isn’t about genetics, though people like to say it is.
It’s about a collection of habits, most of them practiced far from the grandkids, that build the kind of stamina that lets you show up and stay in it when it counts.
Psychologists who study aging say the grandparents who keep up didn’t stumble into energy. They chose it, one ordinary day at a time. You can choose it too.
1. Move every day, not just for visits
If you want to chase a toddler at four in the afternoon, you can’t start warming up that morning.
Walk the neighborhood before breakfast. Take the stairs instead of the elevator at the doctor’s office. Bend down to pull weeds in the garden on a Wednesday.
Consistent daily activity, even at moderate intensity, preserves your mobility, your balance, and the kind of baseline energy that lets you say yes to a game of tag without hesitating.
It doesn’t have to be ambitious. A twenty-minute walk counts. Carrying the groceries inside instead of waiting for help counts.
What matters is that your body stays accustomed to being used, so it doesn’t freeze up when a grandchild grabs your hand and starts running.
Don’t treat movement as preparation for a visit. Treat it as part of how you live. By the time the grandkids arrive, you want to have already been in motion for weeks.
2. Take sleep as seriously as you take the grandkids
Go to bed at the same time most nights. Don’t fall asleep with the television on. Stop saying yes to the late phone call on a weeknight, because the next morning always makes you pay for it.
At thirty-five, you could run on five hours and bluff your way through the day. At sixty-five, that doesn’t work anymore. Your body keeps a closer record now.
Researcher Leonie Balter at Stockholm University found that even two nights of poor sleep made people feel more than four years older than their age. People who reported feeling well rested, on the other hand, consistently felt younger.
That gap is the distance between keeping up and sitting down. Sleep isn’t a luxury past sixty. It’s the infrastructure.

3. Eat for stamina, not speed
Eggs and toast instead of a pastry from the corner bakery. A real lunch instead of crackers at the counter. Water on the nightstand, fruit in the kitchen, protein at every meal because your muscles need it more now, not less.
You don’t need a plan or a calculator. Stop treating meals as interruptions and start treating them as fuel. Eat breakfast before nine, not at eleven. Sit down for lunch instead of grazing over the sink.
If you skip a meal, you’ll run out of energy at three in the afternoon, right when a five-year-old is hitting full speed.
Your body at sixty-five doesn’t recover from poor nutrition the way it did at forty. If you eat well at home, you’re the one who can keep going at the park without needing to sit down after twenty minutes.
4. Keep learning things that have nothing to do with family
Pick up watercolors at sixty-eight. Start reading about architecture. Join a group that meets on Thursday mornings to talk about history.
Nobody in your family has to ask you to do any of it, and nobody in the family has to understand why you care so much about it. That’s part of the point.
Psychologists who study aging have found that staying curious, especially about topics that tap into existing knowledge, keeps the mind flexible. That flexibility is what lets you follow a five-year-old’s invented game, pivot when the rules change mid-sentence, and stay engaged instead of overwhelmed.
The grandparent who still learns is the grandparent who can play. Learning keeps you in the habit of encountering something unfamiliar and staying with it instead of shutting down. That’s exactly what a toddler demands.
5. Build the kind of strength the floor requires
The real test isn’t a gym. It’s a living room carpet. Can you get down to a toddler’s level, sit cross-legged, stack blocks, and get back up without grabbing the couch?
Most people don’t think about this until the moment arrives and their knees say no. If you want to keep up, you need to know what that moment asks of your body and start preparing for it now.
Psychologist Sarah Grainger at the University of Queensland, writing about active grandparenting, notes that grandparents tend to be more physically active and less sedentary on the days they spend with grandkids.
Pushing a stroller, lifting a toddler, bending to tie a shoe: all of it demands functional strength.
Build that strength on your own time, through squats, balance exercises, and core work. Practice the movements in a gym or a living room for months.
When a grandchild holds out their arms, you won’t have to calculate whether you can manage it. You’ll already know.

6. Stay connected between visits
Wednesday lunch with a friend. A morning walk with a neighbor. A phone call that lasts longer than five minutes, with someone who knows your name and asks how you’re doing.
If you stay in touch with other adults, that connection isn’t separate from your energy with the grandkids. It’s part of what sustains it.
Social isolation drains older adults in ways that show up physically: lower motivation, less movement, more fatigue. If you see nobody between one trip and the next, you’re drawing from a well that never gets refilled.
Stay connected. Have people expecting you places, because that means you’re getting dressed, getting out, and staying in the rhythm of engagement.
Don’t rely on time with the grandkids as your only source of contact. Have a life that runs between those visits, and that life will give you the reserves to be fully present when the grandkids walk through the door.
7. Find a reason to stay well, independent of your family
The reason to stay active has to be yours.
A trip you want to take. A project you’re in the middle of. A garden you’re redesigning. A version of next year you can see clearly and want to be around for.
A study published in JAMA Psychiatry, covered in a feature on purpose and physical function, found that older adults with a stronger sense of purpose maintained better physical function over time, including grip strength and walking speed.
You can love your grandkids and still need a reason to stay well that doesn’t begin and end with visits to them. Make it broader than that, rooted in your own life, your own goals, your own sense that you’re not done yet.
The grandkids don’t create the energy. They’re the reason the energy gets used.
