Can we have a chat about belly fat. You’ve been hitting the gym, crushing your workouts, maybe even eating salads like they’re going out of style. Yet, despite all your hard work, that stubborn belly fat just won’t budge.
Sound familiar? I’m guessing it does.
Here’s the thing: What if the type of workouts you’re doing—those sweat-drenched, heart-pumping, go-hard-or-go-home sessions—are actually working against you? Crazy, right?
But it’s true. That’s where cortisol, the sneaky little hormone that controls your stress response, comes into play. And let me tell you, when cortisol is out of control, so is your belly fat.
In this post, we’re going to talk about the best workouts to burn belly fat, break down how certain types of exercise can actually raise your cortisol levels and sabotage your weight loss efforts. More importantly, we’ll dive into how the right type of exercise can help lower cortisol, reduce stress, and finally target that belly fat you’ve been fighting for so long. Ready to take control? Let’s go!
How Cortisol Affects Your Body—and Your Belly Fat
First, let’s talk about what cortisol actually is. Cortisol is a hormone produced by your adrenal glands in response to stress. Whether it’s mental stress (like work, finances, relationships) or physical stress (like high-intensity workouts), your body releases cortisol to help you cope.
Here’s where it gets tricky: When cortisol levels remain elevated for too long, your body starts holding onto fat—particularly around your belly.
Here’s how cortisol leads to belly fat:
Cortisol triggers fat storage: When you’re stressed, cortisol tells your body to store energy as fat, particularly around your midsection. Your body does this to ensure you have enough energy for future "threats." Problem is, most of us aren’t running from predators, but our bodies are still wired to react this way.
Increased cravings: High cortisol also increases your cravings for comfort foods—think sugar and carbs. This is why stress eating is a real thing. Your body craves quick energy to deal with the perceived threat.
Slowed metabolism: Long-term elevated cortisol slows your metabolism, making it harder to burn calories effectively and lose weight, especially around your belly.
How the Right Exercise Lowers Cortisol
Okay, now that we’ve covered how cortisol wreaks havoc on your waistline, let’s talk about how to lower it—and the key here is exercise. But not just any exercise. You have to be smart about it.
The right kind of exercise can lower cortisol levels, reduce stress, and help your body let go of that stubborn belly fat. But before we get into specific workouts, let’s explore why exercise can be so effective at balancing cortisol.
1. Exercise Reduces Stress and Anxiety
One of the biggest ways exercise helps lower cortisol is by reducing stress and anxiety. Here’s how it works: When you exercise, your body releases endorphins—those feel-good chemicals that boost your mood and reduce feelings of stress. At the same time, exercise helps take your mind off of whatever’s causing you stress in the first place.
When stress goes down, so does cortisol.
But not all exercise is created equal here. If you’re already feeling overwhelmed and exhausted, adding a grueling workout to the mix could actually raise your cortisol levels. Instead, focusing on lower-intensity, calming exercises (like yoga or walking) can help your body enter a more relaxed state, reducing cortisol and the stress that causes it.
2. Exercise Regulates Your Sleep Cycle
Sleep and cortisol are intimately connected. Poor sleep raises cortisol, which in turn makes it harder to fall asleep—and then you’re stuck in a vicious cycle. Fortunately, exercise can help break that cycle.
Regular physical activity—especially during the day—helps regulate your body’s natural sleep-wake cycle, also known as your circadian rhythm. When your circadian rhythm is balanced, your body is better able to control cortisol levels, which results in better sleep and fewer middle-of-the-night wake-ups.
But, again, it’s all about the type of exercise. High-intensity exercise late at night can disrupt your sleep and spike cortisol, while moderate-intensity exercise like walking, swimming, or yoga can have a calming effect, helping you sleep more deeply and wake up feeling refreshed.
3. Exercise Helps Balance Other Hormones
Here’s a little secret: When you exercise smartly, you’re not just balancing cortisol—you’re also balancing other hormones that play a key role in fat storage and metabolism.
Insulin, for example, helps control blood sugar and fat storage. High cortisol can make your body more resistant to insulin, which causes your blood sugar to spike and your body to store more fat (again, especially around the belly). Exercise helps regulate insulin sensitivity, meaning your body can better use the glucose (sugar) in your blood and store less fat.
Then there’s estrogen and progesterone, two hormones that fluctuate wildly during perimenopause and menopause. These hormone shifts can cause your body to store more fat around your midsection. But by lowering cortisol through exercise, you’re also helping your body regulate these other hormones more effectively, which in turn can reduce fat storage.
4. Exercise Lowers Inflammation
Chronic stress doesn’t just raise cortisol levels—it also causes inflammation throughout the body. And guess what? Inflammation and belly fat go hand in hand. When your body is inflamed, it has a harder time burning fat and regulating hormones, including cortisol.
Exercise helps reduce inflammation by improving circulation, promoting cellular repair, and helping your body flush out toxins. The key here is to focus on moderate, consistent movement. High-intensity exercise, especially when done too frequently, can actually increase inflammation, making your belly fat even more stubborn.
Low-impact, cortisol-friendly exercises like walking, swimming, yoga, and Pilates, on the other hand, help reduce inflammation without overtaxing your system. When inflammation goes down, so does cortisol—and that’s when your body can finally start burning fat more effectively.
5. Exercise Improves Mind-Body Connection
It’s easy to think of exercise as purely physical, but the best types of workouts—especially when it comes to reducing cortisol—are those that also involve a mind-body connection.
Exercises like yoga, Pilates, and tai chi encourage you to focus on your breath, movement, and posture. This heightened awareness helps calm your nervous system and activate your parasympathetic nervous system—the part of your nervous system that controls your body's "rest and digest" functions.
When your parasympathetic nervous system is activated, your heart rate slows down, your muscles relax, and your cortisol levels drop. In fact, research has shown that practicing mindfulness and slow, deliberate movements (like those in yoga and Pilates) can lower cortisol more effectively than many other forms of exercise.
So, if you’re serious about lowering cortisol and burning belly fat, it’s time to start focusing on exercises that promote that mind-body connection—whether that’s through yoga, Pilates, or simply paying more attention to your breath and movement during your daily workouts.
Why High-Intensity Exercise Can Spike Cortisol and Slow Fat Loss
Now that we’ve established how exercise can lower cortisol, it’s important to talk about the flip side—how the wrong type of exercise can actually spike cortisol and slow down your fat loss efforts.
I know what you’re thinking: “But high-intensity workouts are supposed to burn fat faster, right?”
Well, yes and no.
High-intensity workouts like CrossFit, spin classes, and boot camps definitely have their benefits, but they also come with a downside. When you push your body too hard, too often, your cortisol levels skyrocket. And here’s the thing: If your cortisol is already high due to stress, poor sleep, or hormonal imbalances (looking at you, menopause), adding more stress through intense exercise can backfire.
Here’s how high-intensity exercise can sabotage your fat loss efforts:
1. Cortisol Stays Elevated for Too Long
High-intensity exercise increases cortisol temporarily, which is fine in small doses. But if you’re doing HIIT or intense cardio every day, your cortisol levels may stay elevated for longer than your body can handle. This can lead to muscle breakdown (which you definitely don’t want, especially during menopause when muscle mass already declines), increased fat storage, and even a suppressed immune system.
2. Chronic Stress on Your Body
Your body can’t tell the difference between the stress of a crazy workday and the stress of an intense workout. When you’re already dealing with high stress levels, adding more intense exercise to the mix just piles on the pressure. And guess what happens when your body is in a constant state of stress? You hold onto fat, particularly in your belly.
3. Overtraining and Burnout
Another problem with high-intensity exercise is the risk of overtraining. When you overtrain, your body doesn’t have enough time to recover between sessions, which leads to fatigue, increased cortisol levels, and—you guessed it—fat retention. Overtraining can also make it harder to get quality sleep, which raises cortisol even further.
The Best Workouts to Lower Cortisol and Burn Belly Fat
So now that we’ve covered why overdoing it with intense workouts can raise cortisol, let’s talk about the best types of exercise to actually lower cortisol and target belly fat.
1. Walking: Walking is a simple yet powerful way to burn calories, lower cortisol, and reduce belly fat. It’s low-impact, which means it won’t spike cortisol levels, and you can do it every day without worrying about overtraining. Plus, walking outside (especially in nature) has been shown to reduce stress and lower cortisol even more effectively.
2. Yoga: Yoga is one of the most effective ways to lower cortisol and promote relaxation. The combination of deep breathing, mindful movement, and stretching helps calm your nervous system, reduce inflammation, and balance hormones. Even just a few sessions of restorative or yin yoga each week can have a dramatic impact on your stress levels and fat loss.
3. Pilates: Pilates focuses on core strength, flexibility, and controlled movements—all of which help reduce cortisol and tone your muscles. It’s especially beneficial for women going through menopause, as it helps improve posture and core stability while being gentle on the joints.
4. Strength Training: Lifting weights is an excellent way to build muscle and burn fat without spiking cortisol. The key is to avoid overtraining—stick to moderate weights and focus on full-body workouts 2-3 times a week. By building more muscle, you’ll boost your metabolism and burn more calories, even at rest.
5. HIIT (in moderation): While high-intensity interval training can spike cortisol if done too frequently, short bursts of HIIT (1-2 times a week) can be effective for fat loss without overloading your system. The key is to keep sessions short (20-30 minutes) and to balance them with lower-intensity workouts throughout the week.
