Somewhere along the way, women over 40 finally started getting the message:
Lift heavy weights.
Eat enough protein.
Walk every day.
And honestly? I love that.
After decades of women being told to eat less, shrink smaller, and spend hours burning calories on cardio machines, we are finally having a smarter conversation about building muscle, protecting metabolism, and fueling our bodies.
However, there is one piece of the longevity conversation that is getting pushed aside.
Your cardiovascular fitness.
Because while muscle matters — and trust me, as a former professional bodybuilder, I will always tell women to build and protect muscle — we cannot forget this:
Heart disease is still the #1 killer of women.
Not aging.
Not weight gain.
Not menopause.
Heart disease.
And one of the most powerful tools we have to protect our heart may take less time than you think.
Walking is incredible.
Daily movement helps improve insulin sensitivity, supports mental health, reduces stress, and keeps your body functioning well. In fact, I encourage almost every woman I work with to walk consistently.
However, walking and cardiovascular training are not exactly the same thing.
This is where many women get stuck.
They are hitting their steps.
They are lifting weights.
They are eating protein.
But they are never actually challenging their cardiovascular system.
Think about it this way:
Your muscles get stronger because you ask them to do something harder than they are used to doing.
Your heart works the same way.
If your heart rate never increases, if your breathing never changes, and if your body never has to adapt to a higher demand, you may be missing an important piece of your longevity plan.
Dr. Vonda Wright, orthopedic surgeon and longevity expert, has talked about the importance of adding short bursts of “breathless exercise” into your routine.
The idea is simple:
Spend intentional time pushing your cardiovascular system to a level where talking becomes difficult.
You are not casually walking.
You are not scrolling on your phone.
You are not comfortably moving.
Instead, you are creating a short period where your heart, lungs, and muscles have to work harder.
Examples may include:
The goal is not destroying yourself.
The goal is creating a stimulus.
Here is where the science gets exciting.
Research on vigorous exercise shows that even small amounts of higher-intensity movement can create major health benefits.
One reason is something called VO₂ max.
VO₂ max measures how efficiently your body uses oxygen during exercise. In simple terms, it tells us how well your heart, lungs, blood vessels, and muscles work together.
Higher cardiovascular fitness is strongly associated with better longevity and lower risk of disease.
And here is the part many women miss:
You usually do not significantly improve VO₂ max by staying comfortable.
Your body adapts when it is challenged.
That means short periods of higher effort can improve cardiovascular fitness in ways that casual movement alone often cannot.
As hormones shift during midlife, women experience changes that go far beyond hot flashes.
Declining estrogen levels can impact:
This is one reason many women notice more belly fat during perimenopause and menopause.
However, hormonal belly fat is not only about how your jeans fit.
Increased visceral fat — the deeper abdominal fat stored around your organs — is associated with higher risk of metabolic issues and cardiovascular disease.
This is exactly why our conversations around health after 40 need to be bigger than weight loss.
Yes, we want to feel confident.
Yes, we want strong bodies.
But more importantly, we want bodies that support us for decades.
Absolutely not.
Walking is still one of the best daily habits you can build.
However, your 10,000 steps and your breathless exercise have different jobs.
Think of walking as your foundation.
It helps with:
Higher intensity exercise builds another layer by improving cardiovascular capacity.
The magic happens when we stop asking, “Which one is better?” and start asking, “What does my body actually need?”
For most women over 40, the answer is:
Strength training + daily movement + enough protein + intentional cardiovascular challenge.
The good news?
You do not need another hour-long workout.
Start small.
Try adding 10 minutes, 2–3 times per week, where you intentionally increase your effort.
For example:
Warm up for a few minutes.
Then alternate:
30 seconds harder effort
90 seconds recovery
Repeat until you reach 10 minutes.
Your “hard” should feel challenging but controlled.
Remember, the goal is not punishment.
The goal is building a stronger, healthier, more resilient body.
I love seeing women finally embrace muscle. (Need a place to start with lifting?)
I love seeing women eat more protein. (Need a way to get in more protein?)
I love seeing women stop chasing skinny and start chasing strength.
But strength is not just about the muscles you see in the mirror.
It is also about the heart that allows you to live the life you are working so hard to create.
Lift your weights.
Eat your protein.
Take your walks.
And a few times a week?
Get a little breathless.
Your future self will thank you.
