If your fitness routine looks like hopping from one HIIT class to the next, squeezing in runs between errands, and checking your smartwatch like it’s the boss of you… we need to chat.
Because if you’re doing all the cardio, sweating buckets, and still not seeing the results you want—it’s not because you’re not trying hard enough. It’s because your body is asking for something different.
Spoiler alert: it’s time to start lifting.
And no, we’re not talking about bulking up or turning into a bodybuilder (unless you want to!). We’re talking about building lean muscle, supporting your metabolism, protecting your joints, and aging like a total powerhouse.
Let’s dig into why strength training needs to be your new best friend—and why doing high-intensity cardio every single day might actually be holding you back.
Cardio Isn’t Bad… But It’s Not the Whole Picture
Let’s give cardio the credit it deserves. It’s great for:
- Heart health
- Boosting mood (hello, stress relief)
- Burning calories in the moment
- Getting in a quick sweat when time is tight
But too much of it—especially the high-intensity kind—can work against your goals if you’re not balancing it out with strength training.
Think of it like this: cardio is the cute outfit. Strength training is the supportive bra underneath holding it all together.
Why Strength Training Should Be the Star of Your Workouts (Especially After 35)
Here’s the truth no one tells you in spin class:
After age 30, we naturally start to lose muscle—about 3–8% per decade. After 50? That number goes up even more. Less muscle means a slower metabolism, more fatigue, higher risk of injury, and—yep—more stubborn fat.
The fix? Strength training.
When you lift weights (or use resistance), you:
- Build and keep lean muscle
- Increase bone density (super important for preventing osteoporosis)
- Boost your metabolism (even while you’re binge-watching Netflix)
- Sculpt your body in a way cardio just can’t
- Get stronger for real life—carrying groceries, playing with kids, climbing stairs without huffing
And let’s be honest… there’s something empowering about lifting heavy things and surprising yourself.
5 Reasons You Don’t Need to Do High-Intensity Cardio Every Day
If your current strategy is “sweat until you collapse,” it might be time for a new plan. Here’s why:
1. Too Much Cardio Can Spike Cortisol
High-intensity workouts can stress your body out. And if you’re already juggling a job, family, and everything else on your plate, adding more physical stress can leave you drained—not energized. Elevated cortisol can lead to stubborn belly fat, poor sleep, and burnout.
2. It Can Lead to Muscle Loss
When you do tons of cardio without strength training, your body doesn’t just burn fat—it can burn muscle too. And we want to keep that precious muscle, because it keeps our metabolism revving and our bodies looking toned and firm.
3. It Raises Your Risk of Injury
Repetitive movements, impact, and overuse without proper recovery? That’s a recipe for injury. Strength training helps protect your joints, improve your posture, and prevent aches and pains—especially as we get older.
4. It Can Actually Stall Fat Loss
More cardio doesn’t always mean more fat loss. Your body gets efficient, and eventually, you have to do more to get the same results. Strength training, on the other hand, helps you build muscle and burn more calories at rest. That’s the long game.
5. It’s Not Sustainable
Let’s be real: you probably don’t want to bounce around doing burpees 6 days a week for the rest of your life. That’s exhausting. Sustainable results come from smart training, not punishment.
What Should You Actually Be Doing?
Here’s the magic formula we recommend for women in your 30s, 40s, and 50s:
✅ Strength Train 2–4 Times Per Week
Focus on full-body workouts that challenge you and help build lean muscle. Think squats, deadlifts, rows, presses—all the stuff that helps you feel strong in your everyday life.
✅ Add in Cardio… But Don’t Let It Run the Show
Cardio is still great! Just don’t let it dominate your week. 1–2 sessions of low-impact or interval-style cardio (walking, cycling, or short, smart circuits) is plenty to support heart health without draining your energy.
✅ Choose a Gym That Offers Both
If your gym is all bootcamp or all cardio-based classes, it might be time to upgrade. Look for a place that programs workouts specifically for women who want to build strength, stay lean, and train for life, not just calorie burn.

If you’re near us, shameless plug: we do just that. We’ve built a space for women over 35 who want real results, real support, and workouts that actually work with your body, not against it.
P.S. Your Watch Isn’t the Boss of You
Look, we love a good fitness tracker. But if your motivation lives and dies by how many calories your watch says you burned… it’s time to take a step back.
Your watch doesn’t know how strong you’re getting.
It doesn’t know that your knees don’t hurt anymore.
It doesn’t know that you crushed a hike without needing to lie down after.
It doesn’t know you’re standing taller, feeling better, and finally loving the way you move.
Progress isn’t always measured in numbers. Sometimes it’s measured in how you feel when you zip up your jeans or carry that 40-pound bag of dog food like a champ.
Final Thoughts, Girlfriend
You don’t need to crush yourself with cardio to be fit.
You don’t need to chase a calorie burn every day to lose weight.
You definitely don’t need to feel sore, tired, and burnt out all the time.
What you need is a plan that builds you up—not tears you down.
Strength is the secret sauce. It helps you move better, look better, and live better—especially in your 40s and beyond. And no, it’s never too late to start.
So let’s stop chasing sweat for sweat’s sake, and start training with purpose.
You deserve workouts that make you feel strong, confident, and unstoppable.
