You’re doing everything right. You’re showing up. You’re pushing through. You’re working out more than you ever have and somehow your body isn’t responding the way it used to.
If that’s you, you are not doing it wrong. Your body is doing something different.
Once I understood what was actually happening in my own body after 40, everything changed. I mean I knew it was coming. I watched my mom go through hot flashes and laugh. She used to say she was, “going through the change.” I didn’t understand it then but I definitely do now. “The change” is very accurate.
The body changes were already happening at 40 but it didn’t really hit me until around 45. That’s when I really started to notice that things weren’t changing as fast as they used to. Not because I wasn’t working out hard enough, but because I finally stopped trying to.
Your Body After 40 Is Playing by Different Rules
Here’s the thing nobody tells you when you hit your 40s: the workouts that used to work can actually start working against you.
I’ve been doing some research on the why and how. And by research I mean Google and what I found was interesting.
When we push really hard like with super long cardio sessions, back-to-back intense workouts, without taking any rest; our bodies release a stress response. That stress response is normal. It’s how we get stronger.
But after 40, especially if you’re in perimenopause or heading that direction, your body has a harder time recovering from that stress. It stays in that heightened state longer. When that happens, your body actually holds onto weight, especially around the stomach. You feel more tired, not less. You’re sore longer. Your sleep gets worse. Sometimes it feels like you’re working harder and feeling worse and it makes no sense. Until you understand what’s happening.
More Is Not Always More
I used to think the answer was always to do more. More reps. More days. More intensity. Push through the tired. Earn the rest.
That mindset hasn’t served me after lately. Although I do admit that I never take a full rest day. I’m not there yet. Even if it’s a 2 mile walk around the neighborhood; I’m moving daily. The feeling I get after a sweat session never gets old. Stress and worry is always gone when I’m done moving.

This consistency of movement I built up is why I like to move daily. What actually started helping me was just doing it consistently. Shorter workouts sometimes. More rest between sets. Strength training instead of only long cardio. And honestly? More sleep.
Sleep has been a game changer! My 5am workouts are greatly affected by the time I go to bed the night before.
Magnesium is also supposed to help with perimenopause symptoms. It’s said to help with sleep, hot flashes, muscles cramps and more. I just ordered this one from Amazon if you want to try it with me. I’ll get back to you on how it makes me feel after I’ve tried it for a bit.
I also made a whole YouTube video about movements. It’s a Perimenopause Workout: Effective Strength Routine You Can Do at Home. I walk you through five moves you can do instead of grinding through high-intensity sessions. You can do them alone or add them to your current plan. It’s real, it’s simple, and it’s built for the body we actually have right now.
Go watch it. Then come back here.
A Simple Week That Actually Works
This is roughly what a week can look like:
• Monday — 20-minute strength (lower body focus)
• Tuesday — 20-minute walk
• Wednesday — 20-minute strength (upper body focus)
• Thursday — rest
• Friday — full body (strength & cardio)
• Weekend — movement that feels good like playing at the park with the kids, shopping with friends, neighborhood walk, hikes, etc; no pressure
Some weeks look exactly like that. Some weeks Monday becomes Wednesday and Friday disappears entirely. That’s okay. Showing up imperfectly is still showing up. Consistency is key. Once you get a flow, you can build upon that. (If you choose to.)

If you want a gentle place to start, my Quiet Rebuild Starter Guide is free and gives you a simple framework to build from and there’s no gym required.
And if you’re specifically navigating perimenopause or menopause, I also have a 7-Day Midlife Reset Guide built specifically for where you are right now.
You Don’t Have to Earn Rest
The biggest shift for me wasn’t a new workout. It was giving myself permission to stop treating rest like a failure. And I’m still working on it.
Just know that…you are not behind. You are not broken. Your body is changing, and it’s asking you to change with it not fight it.
Work smarter. Rest on purpose. Show up consistently. That’s the whole thing.
