Parent Marathon Month: Quick HIIT Routines That Fit Carpool Windows
As a family physician in Cherry Creek, I see the same pattern every fall: parents who are managing everyone’s health but their own. The mental load climbs, sleep shortens, and the stress that used to sit quietly in the background starts showing up as headaches, short fuses, and 3 p.m. crashes. When I ask what changed, the honest answer is usually "there’s no time."
Here is what I tell my patients. You do not need an hour or a gym to protect your health during the busiest stretch of the year. You need ten minutes and a plan that survives a real schedule. Short bursts of movement lower cortisol, steady blood sugar, and improve sleep, and they do it in the windows you already have, between drop-off and your first meeting. Below are the routines I actually recommend, built for the life you have right now, not the one you keep promising yourself you’ll have "once things calm down."
The Myth of “When Things Calm Down”
At some point, most parents tell themselves they’ll start taking care of their health once things settle. The problem is, things don’t settle. There’s always another round of school events, another sports season, another work push. Waiting for calm is like waiting for perfect conditions to go for a run in Denver—you’ll be waiting through heat, hail, wind, and wildfire smoke.
Instead, the goal becomes finding ways to move that fit inside your reality. Not in spite of it.
This is where HIIT—high-intensity interval training—can be a real game-changer for busy parents.
Why HIIT Works for This Season of Life
HIIT isn’t about punishment. It’s not about pushing yourself until you drop. It’s about efficiency. In just 10–20 minutes, you can improve cardiovascular health, build strength, and lower stress—all without leaving your neighborhood or changing into fancy workout gear.
A HIIT workout combines short bursts of effort with brief rest periods. It can be done with bodyweight alone, in your garage, in the park, or even next to your car while you’re waiting at soccer practice. The key is intensity—giving your best effort during those short intervals—and then allowing your body to recover.
The best part? These workouts are flexible. You can scale them up or down based on your energy, your time, or what your day looks like.
What This Looks Like in Real Life
Let’s say you’ve got 15 minutes between drop-off and your next meeting. That’s enough.
Here’s a simple, equipment-free routine you can do just about anywhere:
Three-Round Parent Reset
40 seconds of squats
20 seconds rest
40 seconds of jumping jacks (or modified step jacks)
20 seconds rest
40 seconds of push-ups (on your knees or at an incline if needed)
20 seconds rest
40 seconds of alternating lunges
20 seconds rest
40 seconds of mountain climbers or high knees
20 seconds rest
Repeat this sequence up to three times, or just do one round and call it a win. If you can fit in a walk later? Even better. But if not—you moved, you sweated, and you gave your nervous system a boost.
What Really Changes When You Move
You’re not just checking a fitness box. You’re changing your chemistry. Moving your body helps regulate cortisol (the stress hormone), boosts serotonin (your mood stabilizer), and sharpens your ability to focus. It can help you sleep better. It can make it easier to get through those 3 p.m. crashes without needing an entire sleeve of cookies.
And no, you don’t need to do it every day. Three times a week is enough to see real benefits. That said, once you start, you might find your body asking for it more often—not out of guilt, but because it feels good.
This Month, Make a Move for You
At our practice, we’re kicking off what we’re calling Parent Marathon Month. It’s not a real marathon, thankfully—but it is a chance to check in on the patterns that might be quietly wearing you down and replace them with ones that build you back up.
We’re encouraging our patients to carve out a few 10–15 minute pockets each week for movement. It doesn’t have to be structured. It doesn’t have to be beautiful. It just has to happen.
If you want support in making a plan that works for your body—especially if you’re dealing with chronic stress, fatigue, joint pain, or hormonal shifts—we can help you build something sustainable. Because what works for your twenty-year-old neighbor probably won’t work for you, and that’s okay.
You’re Allowed to Be a Priority
This month might feel like it’s all about everyone else. School needs. Work demands. After-school chaos. But somewhere in all that movement, there’s space for you, too.
You don’t need a new personality or a perfect morning routine. You just need a small window—and a little permission—to take care of your body in the time you have. Not later. Not once the season ends. Now.
Ten minutes. No gym. No guilt.
