There’s a particular kind of exhausted that hits in your 40s that nobody really prepares you for.
It’s not the tired-from-a-bad-night’s-sleep kind. It’s the woke-up-already-drained, hot-at-2am, body-feels-different-than-it-did-two-years-ago kind. The kind where you want to move your body but every workout you try feels like it was designed for someone ten years younger and three hormone cycles behind you.
I know that feeling because I’ve been in it. Just last night, I woke up five times from hot flashes. I know what the internet tells you to do: more cardio, sweat it out, push harder. I tried that and didn’t see results anymore.
But here’s what nobody told me… that advice was actually working against me because of perimenopause. The research is clear, and once I understood it, everything about how I approach my workouts changed.
The answer isn’t more cardio. Although, I still do cardio. But the real sauce is strength training. It doesn’t have to be complicated, heavy, or long.
Why Strength Training Is the Most Important Thing You Can Do During Perimenopause
Estrogen decline begins years before your last period, often in your late 30s or early 40s. Your body loses its natural muscle-preservation support system. Estrogen plays a direct role in maintaining muscle mass and bone density. When it drops, both drop with it, often faster than you’d expect.
This is why so many women in perimenopause notice weight redistribution (especially around the midsection), reduced energy, and a sense that their body composition is changing even when nothing in their diet or routine has. It’s not a willpower problem. It’s hormonal physiology.
Strength training directly addresses this. Lifting even light weights signals your body to preserve and build lean muscle, which:
• Increases your resting metabolic rate (so your body burns more calories at rest)
• Supports bone density at a time when it’s most at risk
• Improves insulin sensitivity, which reduces fat storage around the belly
• Regulates mood and sleep through the release of endorphins and growth hormone
• Reduces the severity of perimenopause symptoms over time
The research isn’t subtle on this. A 2022 study published in Menopause: The Journal of The Menopause Society found that resistance training significantly improved body composition, muscle strength, and quality of life in perimenopausal women without requiring high intensity.
Low impact does not mean low effort. It means smart effort.
What My Workouts Look Like on a Hard Hormone Day
I’ll be honest with you. There are days where a 45-minute workout is just not happening. Hot flash at 3am, my son needs things before I’ve had coffee, the general weight of everything and some days the most I can commit to is increments of 15 minutes and three moves.
Those days, this is what I do.
Three moves. Weights in hand. Done in under 20 minutes including rest. And every single one of them is directly relevant to what your body needs during perimenopause.
The 3 Moves
- Dead Bug with Weights
The dead bug is one of those exercises that looks gentle and absolutely is not. It’s a deep core stability exercise that protects your lower back, strengthens your transverse abdominis (the deep stabilizing muscle that wraps around your spine), and challenges coordination in a way that keeps your nervous system engaged.
During perimenopause, core strength is more important than most people realize. Hormonal shifts affect ligament laxity and joint stability. your core is what compensates for that. A strong core also supports better posture, reduces back pain, and helps regulate intra-abdominal pressure.
How to do it:
Lie on your back with your knees bent at 90 degrees, shins parallel to the floor. Hold a light weight in each hand and extend your arms straight up toward the ceiling. Slowly lower your right arm back toward the floor while simultaneously extending your left leg straight out — hovering both just above the ground. Return to center. Then lower your left arm and right leg. That’s one rep.
Go slow. The slower you go, the harder it works. Keep your lower back pressed into the mat throughout.
Equipment: Light dumbbells, 3–8 lbs depending on where you are.

- Alternating Reverse Lunge with Weights
The reverse lunge is a single-leg movement, which means it trains balance, hip stability, and unilateral (one-sided) strength simultaneously. For perimenopausal women, this is crucial — single-leg movements help prevent the muscle imbalances that can lead to knee and hip problems as we age.
The reverse lunge is also significantly more joint-friendly than a forward lunge. The movement pattern reduces shear force on the knee, making it accessible even on days when your joints feel sore or inflamed (which, thanks to estrogen’s anti-inflammatory role declining, is more common in perimenopause than most people expect).
Lower body strength is your metabolic engine. The more muscle you have in your legs and glutes, the higher your resting metabolic rate — and the more effectively your body manages blood sugar and weight.
How to do it:
Stand tall holding a weight in each hand at your sides. Step your right foot back and lower your right knee toward the floor, keeping your front shin as vertical as possible and your chest up. Press through your left heel to return to standing, then bring your right foot back to meet your left. Alternate sides with each rep.
Equipment: Medium dumbbells, 8–15 lbs. Start lighter than you think you need to.

Upper body pulling movements are criminally underrepresented in most women’s fitness content, and it costs us. The bent-over row strengthens your upper back, rear deltoids, and biceps — the muscles responsible for posture, shoulder stability, and counteracting the forward rounding that happens when we’re hunched over phones, kids, and desk work all day.
During perimenopause, back health becomes even more critical as bone density in the spine begins to decline. Strengthening the muscles that support the spine directly helps protect it. Strong upper back muscles also help prevent the postural changes that become more common as estrogen drops.
How to do it:
Hinge forward at the hips with a soft bend in your knees, keeping your back flat and your core engaged. Let the weights hang in front of you. Drive your elbows back and up, squeezing your shoulder blades together as you pull the weights toward your lower ribcage. Lower with control. That’s one rep.
Don’t rush this one. The lowering phase (the eccentric) is where a significant portion of the muscle-building stimulus happens.
Equipment: Medium dumbbells, 10–20 lbs depending on your current strength.

A Sample Workout for a Hard Hormone Day
This is the actual workout. No warm-up theatrics, no 47-step routine. Just movement.
Do 3 rounds:
• Dead Bug with Weights — 8 reps (4 each side)
• Up Downs — 10 reps (5 each side)
• Bent-Over Row — 10 reps
• Rest 60 seconds between rounds
Total time: 15–20 minutes.
On a good energy day, add a fourth round or increase your weights slightly. On a low energy day, two rounds still counts. You still showed up.
What to Expect When You Start Strength Training in Perimenopause
The first two to three weeks, your body is learning the movements. Don’t expect to feel dramatically different immediately. What you will notice fairly quickly is better sleep quality (strength training improves deep sleep stages), reduced anxiety, and a general sense of having done something good for yourself.
Over six to eight weeks, you’ll start to notice changes in how your body feels — more stability, less joint soreness, more energy on non-workout days. The hormonal benefits compound over months, not days. Consistency is the whole game here.
You don’t need to lift heavy. You don’t need to train five days a week. You need to show up consistently with weights in your hands and give your body the signal it needs: build muscle, preserve bone, stay strong.
