The Blizzard Workout That Can Kill You
Every year, like clockwork, snow falls… and so do a subset of middle-aged men with shovels.
We joke about it. The guy in shorts is clearing his driveway at 6 a.m. in a blizzard. The neighbor who treats a Nor’easter like it’s the CrossFit Games. But here’s the punchline that isn’t funny: intense, unaccustomed exertion, especially in cold weather, can be lethal.
When Zone 5 Finds You (With a Shovel)
I learned this the hard way. After a recent storm, I decided to “quickly” clear the driveway and fallen branches. Three hours later, soaked in sweat and snow, I checked my fitness tracker.
The results stopped me cold.
42 Minutes of Overload for Snow Clearing

Snow Clearing Overload Week Summary
That “casual” driveway session equated to 54 minutes in the conditioning zone and 42 minutes in the overload zone—basically Zone 4/5 in traditional training metrics. For context, based on my current fitness and work rate, I intentionally target about five minutes per week reaching overload.
Five.
I accidentally did eight times that before breakfast.
And I’m not alone. A study published in the Canadian Medical Association reported that the incidence of sudden heart attack spikes by about 16% in men of a certain age when it snows, particularly during heavy storms leading to a 34% rise in deaths. That’s not a rounding error. That’s not “statistically interesting.” That’s a body count.
Why snow?
Because it’s the perfect physiologic storm. Cold temperatures constrict blood vessels. Blood pressure rises. Heart rate climbs. Add heavy, wet snow, which can weigh 20+ pounds per shovel and you’ve created high-intensity resistance training layered on top of aerobic strain. Now toss in poor sleep, holiday weight gain, deconditioning, and a dash of male pride (not me of course 😁).
Boom. Cardiovascular roulette.
Men seem to bear the brunt in the data, but let’s not get complacent. The research on women is thinner, probably not because they’re immune, but because historically, cardiovascular research has underrepresented them 🙁. We know women experience heart disease differently: subtler symptoms, later diagnosis, and worse outcomes when missed. It would be naïve to assume the physiology of overload and cold stress somehow spares them. If anything, the data gap should worry us more.
The bigger issue? Most people have no idea where their true conditioning limits are.
That’s where this becomes less about snow and more about systems.
We’ve built a healthcare model where many adults don’t have a meaningful, ongoing relationship with a primary care physician. Not because they don’t want one. Not because doctors don’t care. But because the system doesn’t support, much less pay for, the time required to truly know a patient’s baseline risk, fitness capacity, medication profile, and lifestyle patterns.
When was your last real conversation about exercise tolerance with your doctor? Not a checkbox. Not “you should exercise more.” But a nuanced discussion: What heart rate zones are safe? What’s your risk stratification? How should you scale intensity as you age?
And on that point how many general practitioners or doctors in general are equipped to dive into this in detail or have the remaining energy, having spent so much of their time and energy on dealing with administrative tracking, RVU measures, and increasingly justifying their activity to the new corporate overlords.
Exactly.
Meanwhile, some estimates suggest physicians now spend as much as 70% of their time on administrative tasks, such as documentation, billing codes, prior authorizations, and insurance gymnastics. Seventy percent. That’s not care. That’s clerical burden masquerading as healthcare.
So instead of proactive, preventive guidance, we get reactive medicine. We meet patients in the emergency department after the driveway incident, not in the office before the snowstorm.
And this is solvable.

We can reduce administrative overhead with smarter automation led by Agentic-AI and other AI-facilitated documentation tools. We can streamline prior authorizations. We can shift payment models to reward time spent in prevention rather than throughput volume. We can invest in team-based primary care so physicians practice at the top of their license instead of drowning in paperwork.
Most importantly, we can reestablish continuity, real relationships where your doctor knows that five minutes of overload per week is your norm and can warn you that a three-hour snow marathon is a terrible idea. I can even imagine a regular update coming from your family practitioner that could even be tailored to the patients, but sent out en masse when the local weather gang actually gets the prediction right (thanks to AI 😁) and offering some useful tips to avoid that trip to the emergency room!
Because aging changes the math. Recovery slows. Vascular compliance decreases. Silent coronary disease becomes more common. What felt like “good hard work” at 35 can become catastrophic at 55.
This isn’t an argument against exercise. Quite the opposite. Regular, progressive training lowers cardiovascular risk dramatically. But there’s a difference between structured adaptation and heroic overreach.
Snow shoveling doesn’t care about your VO₂ max aspirations. It’s chaotic, cold, heavy, and ego-driven.
So here’s my advice, learned with a tracker and a raised eyebrow:
- Break the job into intervals.
- Warm up first (yes, really).
- Push lighter loads more often.
- Know your medications.
- Stop when your body says stop.
And maybe, just maybe, ask the 20-year-old down the street if he wants to earn twenty bucks, assuming, of course, that exists in your neighborhood.
Your heart will thank you.
And if we fix primary care access and reduce the bureaucratic drag on physicians, maybe more of us will actually have the kind of guidance that keeps snow days from becoming emergency days.
Until then, respect the shovel. It’s sneakier than it looks.
