480: Running Myth: Women in Menopause Should Just Do HIIT

High Intensity Interval Training (HIIT) and Menopause

You know that feeling when you scroll through social media and suddenly wonder if everything you've been doing is wrong?

One person tells you running is one of the best things you can do for your health. The next tells you that running is raising your cortisol and working against your hormones. Then someone else says that if you're in perimenopause or post-menopause, you should stop doing easy cardio and focus on HIIT, sprinting, and heavy lifting instead.

It's a confusing period of life to navigate, and social media is just making it worse.

As runners, we're already trying to balance training with work, family, stress, sleep, aches, injuries, and all the other things happening in real life. We don't need another rule telling us there is only one "right" way to train.

It’s BS — and I call BS anytime I see it. 

There is no one right way to train, and if anyone says that, unfollow immediately. 

HIIT is valuable. Easy running is valuable. Strength training is valuable. You do not have to choose one and eliminate the others.

The goal is to build a body that is strong, resilient, and capable of handling the kind of running and life you actually want.

HIIT Is a Tool, Not the Whole Training Plan

High-intensity interval training can be a great tool. It can improve VO2 max, provide a strong metabolic stimulus, develop speed and power, challenge the neuromuscular system, and provide the impact needed to stimulate bone remodeling. It can also be a very efficient option when you don't have a lot of time.

Those are real benefits — but effective does not mean complete.

If your goal is body composition or improving a specific aspect of fitness, HIIT may be extremely useful. But if your goal is to run a half marathon, marathon, or ultramarathon, your body still needs to practice being an endurance runner.

You cannot replace all of your easy running with short bursts of hard work and expect the same adaptations.

Your body adapts to what you repeatedly ask it to do.

If you want to become better at running longer, you need to spend time running. You can’t substitute HIIT for volume and expect to get better because adaptation is specific.

Your body adapts to the demands that you place on it. 

So if you spend less time running and more time doing HIIT workouts, your body WILL adapt. It will make changes. The question is simply — are those the adaptations that you want?

Consistent lower-intensity training helps build your aerobic system, including mitochondrial and capillary density, oxygen delivery, metabolic flexibility, and running economy. It also allows you to accumulate more training without the same recovery cost that comes with repeated high-intensity sessions.

That last piece matters.

You may be able to handle one really hard workout.

The question is whether you can recover from it well enough to train again tomorrow, later this week, and next month.

Easy running gives you a way to build fitness through repeated, manageable training.

That becomes one of the most important pieces to consider, especially as we move through perimenopause and post-menopause.

You may notice that you don't recover from hard training the way you used to. Maybe you need more time between intense sessions. Maybe your sleep is less predictable. Maybe life itself is simply more demanding.

That doesn't mean you're broken.

It means recovery needs to be prioritized in your training plan.

One of the problems I see with the “HIIT is better" message is that it ignores the recovery cost of high-intensity training. Higher intensity requires more recovery. Easy aerobic work can often be performed more frequently without creating the same demand.

That’s why we need both. 

I don’t want you to avoid high intensity. I want you to use it intentionally.

There is a big difference between saying, "Intensity is important," and saying, "More intensity is always better."

Those are not the same thing.

As a physical therapist who has helped hundreds of injured runners, there is another piece that we need to consider when deciding if and when to incorporate HIIT: your risk of injury.  

Did you know that your cardiovascular system can improve faster than your tendons, ligaments, bones, and muscles?

You may feel like you can run faster because your heart and lungs are handling the work well, but your connective tissues may not be ready for that increase in mechanical load.

That is one reason runners sometimes feel great during a harder workout and then wake up the next day with a sore knee, irritated Achilles, tight hamstring, or some other new ache.

Your body needs time to adapt.

Easy running and strength training help build that foundation. Then, when your body is ready, you can layer in more speed.

Strides are your best friend

One of the best ways to start to incorporate more speed training into your week are strides. 

These are short, faster efforts, around 15 to 20 seconds, followed by full recovery. They're not all-out sprints. 

We like to recommend 4-6 of them at the end of an easy running. That’s enough to drive adaptation or preserve speed without adding extra recovery time.

You could also use short intervals, such as one minute at a moderately harder effort followed by one to three minutes easy.

Those are very different from asking an underprepared runner to sprint as hard as possible.

You can introduce speed without turning every faster session into a max-effort session.

Don't Let Every Run Become the Gray Zone

One of the biggest traps that I see runners fall into is the “gray zone” — they run moderately hard all the time.

Not easy enough to recover, not hard enough to drive meaningful adaptation. It’s a level that just adds load without intentional benefit.

Easy should actually feel easy.

Sometimes that means slowing down, taking a walk break, or letting your pace be slower than it was six months ago.

Hard should be hard. That doesn’t mean an all-out sprint everytime. Tempo runs, hard intervals, and steady state runs are all valuable tools, if used correctly. 

The key is intention.

Context matters.

Your training should be based on your body, your goals, and your current capacity, not somebody else's 30-second video.

What Your Training Actually Needs

So what does this look like in real life?

For most endurance runners, easy running should make up the majority of training.

You also want some intentional faster running.

You want strength training.

You want mobility and movement work.

And you need recovery.

The harder work can be a smaller portion of the week, often somewhere around 10 to 20 percent, but there is no magic percentage that every runner needs to hit perfectly.

Your training has to account for the whole picture.

If you're sleeping poorly, carrying a lot of life stress, and already struggling to recover, adding more hard workouts may not be the smartest move.

You do not need to find the perfect combination of intervals, strength exercises, running zones, recovery strategies, and training hacks.

You need a foundation you can repeat.

Easy running.

Some intentional intensity.

Strength training.

Mobility.

Recovery.

And enough flexibility to adjust when real life gets in the way.

Because real life will get in the way.

You will have stressful weeks. Your sleep will be off. You will get busy. Your body will occasionally ask you to back off.

That doesn't mean your training isn't working.

It means you're training in a real body while living a real life.

Easy running and intensity can both have a place in your training. The goal is not to find the one perfect method. The goal is to build a strong foundation, add stress gradually, recover from what you do, and keep showing up for the long term.

That's how we build fitness without turning running into another thing we have to perfect.
