Build Strength, Balance Hormones: Why Movement and Muscle Matter More Than Ever in Midlife
Anna Harrelson • March 30, 2025

From insulin resistance to nervous system regulation—how moving your body and building muscle supports you through menopause and beyond.

Lift Heavy!
Let’s be honest: midlife can feel like your body is changing the rules without warning. You’re doing what used to work, but the results aren’t the same. The scale doesn’t budge, your sleep is disrupted, your energy is inconsistent, and your moods might feel like a rollercoaster you didn’t sign up for.

And while hormone therapy, supplements, and nutrition are powerful tools for navigating perimenopause and menopause, movement—especially strength training and nervous system-aware exercise—is one of the most underutilized forms of medicine.

As a lifestyle medicine physician and menopause specialist, I talk about this daily with my patients. Movement isn’t just about burning calories. It’s about retraining your stress response, building metabolic resilience, preserving muscle, and improving insulin sensitivity.

Why Movement and Muscle Matter in Midlife

During perimenopause and menopause, we experience natural declines and fluctuations in estrogen, progesterone, and testosterone. These shifts impact far more than reproduction—they affect how we regulate blood sugar, manage stress, build muscle, sleep, and recover from daily life.

In this stage of life:
  • Muscle mass declines more rapidly if not actively maintained
  • Insulin sensitivity drops, raising the risk for metabolic syndrome and weight gain
  • Cortisol levels rise and become harder to regulate, especially in women with high stress or trauma histories
  • Nervous system resilience weakens, making it harder to bounce back from emotional or physical stressors

Movement is the antidote to all of this.

What the Research Shows

Muscle is a metabolic organ. It stores glucose, improves insulin sensitivity, regulates inflammation, and even contributes to hormone production and detoxification. Building and maintaining muscle in midlife is one of the most powerful ways to protect against:
  • Type 2 diabetes and insulin resistance
  • Cognitive decline
  • Cardiovascular disease
  • Falls, fractures, and osteoporosis
And beyond the physical?   Movement is critical for regulating the autonomic nervous system, which influences:
  • Your ability to sleep
  • Your mood and anxiety levels
  • Your response to daily stressors
  • Your digestive and immune function
Not Just Any Movement

This isn’t about hitting the gym for 90 minutes or going hard every day. It’s about intentional movement that supports your biology.

Here’s what I recommend:

1. Prioritize strength training.
  • 2–3 times per week of bodyweight, resistance bands, dumbbells, or machines
  • Focus on form, tempo, and functional movement—not just reps or weight

2. Include low-impact, nervous-system regulating movement.
  • Walking, mobility flows, Pilates, yoga, or tai chi
  • Think of this as your recovery and resilience training

3. Move throughout the day.
  • Break up sedentary time with stretching, light movement, or standing tasks
  • Movement snacks matter for metabolic health

4. Don’t overtrain.
  • Too much high-intensity exercise can increase cortisol, disrupt sleep, and worsen hormonal symptoms
  • Listen to your body and focus on consistency over intensity

It’s Not About Looking Fit. It’s About Feeling Well.

This phase of life isn’t just about managing symptoms—it’s about building your future resilience. Every time you lift something heavy, take a walk, or stretch with intention, you are:

  • Supporting your insulin and glucose balance
  • Reinforcing your bone, brain, and cardiovascular health
  • Regulating your nervous system
  • Building muscle that keeps you independent and active for decades to come
Movement is medicine, & muscle is your midlife superpower.

Final Thoughts

If you feel like your metabolism has shifted, your sleep is off, or your body feels unfamiliar—you’re not alone. But you’re not broken. You’re evolving. And your body is still responsive to thoughtful support.

Start small. Lift something. Go for a walk. Move in a way that honors your nervous system, builds strength, and reminds you that this phase of life is not a decline—it’s a recalibration.

You know how people say, "Just drink some water and take a magnesium supplement" like it’s the answer to everything? Well… they’re not totally wrong. But like most good advice, the devil is in the details. Magnesium is one of the most essential minerals in the body, involved in over 300 enzymatic reactions , yet it remains one of the most commonly overlooked deficiencies in midlife women. And no, your annual bloodwork probably didn’t catch it. So What Does Magnesium Actually Do? Think of magnesium as a multitasking background assistant—it keeps the lights on and the gears turning across nearly every body system: Brain & Mood: Regulates GABA and NMDA receptors, supporting calm, focus, and resilience against anxiety and overstimulation. Muscles: Prevents cramping and twitching, supports strength and recovery, and reduces restless legs. Sleep: Plays a role in melatonin production and nervous system regulation. Bowel Function: Helps pull water into the colon to prevent constipation. Cardiovascular Health: Regulates blood pressure and helps with vasodilation. Hormone Balance: Assists in estrogen metabolism and combats insulin resistance. In short: if you’re exhausted, bloated, moody, foggy, tense, or irregular in your gut or cycle—magnesium deserves a spot on your radar. Why Is Magnesium So Important in Midlife? Estrogen and progesterone both influence magnesium levels. As hormone levels decline or fluctuate during perimenopause and menopause, so does your ability to retain and utilize magnesium. Add to that: Chronic stress (which depletes magnesium) Modern diets (often low in magnesium-rich whole foods) Medications like PPIs, diuretics, or certain antibiotics High caffeine, sugar, or alcohol intake (all increase magnesium excretion) And suddenly, a " borderline magnesium issue " becomes a perfect storm. Why Your Blood Test Might Not Show It Serum magnesium tests only reflect ~1% of total body magnesium. Most magnesium is stored in bone and tissue. So it’s very possible to have "normal labs" and still be clinically deficient. In practice, we go by symptoms, risk factors, and therapeutic response. Common Signs of Suboptimal Magnesium Trouble falling or staying asleep Anxiety or nervous system overactivation Fatigue or burnout that doesn’t resolve with rest Muscle cramps, spasms, or eye twitches Constipation Menstrual migraines or tension headaches Joint stiffness or tightness Sugar cravings or blood sugar crashes Best Food Sources of Magnesium Magnesium-rich foods include: Dark leafy greens (spinach, chard) Nuts and seeds (especially pumpkin seeds and almonds) Avocados Legumes Dark chocolate (yes, really!) Whole grains like quinoa and oats That said, many of us still fall short even with a healthy diet, especially during high-stress seasons or if absorption is impaired. Supplements: Which Type of Magnesium Is Best? Not all magnesium is created equal. Here are the forms we most often recommend: Magnesium Glycinate: Best for sleep, anxiety, and muscle relaxation. Gentle on the stomach.** Magnesium Citrate: Useful for constipation, but can cause loose stools at higher doses. Magnesium Threonate: May support cognitive function and brain health. Magnesium Malate: Good for energy and muscle pain, often used in fibromyalgia. We generally avoid magnesium oxide unless constipation is the only concern, as it’s poorly absorbed. **Mag Glycinate is generally my go to recommendation and what we take at our house Also, BLENDS can be good- but generally more expensive Dosing & Timing Most women benefit from 200–400 mg daily, depending on needs. Take it in the evening if you're targeting sleep or relaxation. Divide doses if taking more than 300 mg (e.g. AM + PM). Always start low and go slow, especially with citrate forms to avoid urgent bathroom visits. Final Thoughts If magnesium had better marketing, it would be a top-tier wellness darling. But because it’s quiet, essential, and boring on paper, we tend to overlook it. Yet for so many midlife women, magnesium is the missing link that helps all the other systems and strategies finally click. So if you're doing "everything right" and still feel off? It might be time to start taking magnesium!

"Is Ozempic safe?" "Do I have to be diabetic to use it?" "Will I regain weight if I stop?" "I eat well, lift weights, sleep, take hormones—and I still can't lose weight. What's going on?" These are some of the most common questions I hear from women in midlife. And they’re incredibly valid. For decades, the conversation around weight and health has been riddled with shame, assumptions, and surface-level advice. But we’re finally shifting into a new era—one that recognizes obesity as a chronic, complex disease, not a personal failure. One that looks at metabolism through the lens of hormones, inflammation, genetics, stress, and brain chemistry, not just calories in and out. And at the center of this shift is an exciting class of medications known as GLP-1 receptor agonists. What Are GLP-1 Medications? GLP-1 stands for glucagon-like peptide-1, a hormone your body naturally produces in the gut. It helps regulate blood sugar, insulin, and satiety (your sense of fullness). GLP-1s also slow gastric emptying and signal your brain to reduce appetite. Medications like semaglutide (Ozempic, Wegovy), liraglutide (Saxenda, Victoza), and tirzepatide (Mounjaro) mimic this hormone and have been revolutionary for treating type 2 diabetes—and more recently, for metabolic syndrome and obesity. These drugs are not stimulants or fad diet tools. They are hormone-based medications with powerful metabolic and anti-inflammatory effects. Why Are GLP-1s So Relevant for Midlife Women? Midlife is a time of massive hormonal transition. Estrogen, progesterone, and testosterone levels shift dramatically in perimenopause and menopause. This impacts insulin sensitivity, body composition, lipid metabolism, sleep, inflammation, and brain function. Even women who have optimized their lifestyle—dialing in nutrition, strength training, sleep, and hormone therapy—may find themselves stuck. GLP-1 medications can be the missing piece for women who: Have insulin resistance or prediabetes that isn’t budging with lifestyle alone Carry weight disproportionately in the visceral (abdominal) area Are at increased cardiovascular risk due to family history, labs, or existing conditions Are experiencing significant inflammation or joint pain related to metabolic dysfunction Have a history of PCOS or gestational diabetes Are postmenopausal and noticing rapid changes in weight or metabolism These medications work synergistically with hormone therapy and can reduce inflammation, improve insulin sensitivity, and help shift body composition. For some women, they are as life-changing as starting estrogen. It’s Not Just About Weight Loss GLP-1s are being studied for NAFLD (fatty liver), cardiovascular protection, neurodegenerative disease, PCOS, and even addiction and mood regulation. The benefits go far beyond the scale. That said, when stubborn weight is a major barrier to living fully—whether due to physical discomfort, comorbidities, or psychological toll—helping a woman reduce weight safely and effectively can open the door to movement, joy, and hope. So, Who Should Consider a GLP-1? I don’t believe in prescribing these meds as a first-line for someone who hasn’t addressed the basics. That’s not judgment—it’s strategy. If you haven’t worked on: Blood sugar balance through real food Resistance training and daily movement Addressing sleep and circadian rhythms Managing stress and nervous system regulation Optimizing hormones, micronutrients, and gut health … then you’re not giving yourself the best shot at lasting change. But if you have done the work and still feel like your body is working against you—or you have serious metabolic risk factors— then GLP-1 therapy might be a wise and evidence-based next step. Some women use it briefly to reset. Others may need it long-term, just like hormone therapy. It’s not a crutch. It’s a tool. And for the right woman, it can be life-changing. Common Questions I Hear "Will I gain the weight back if I stop?" Maybe—but not always. If the lifestyle foundations are in place, many women maintain progress even after discontinuing. But some women have chronic conditions that benefit from ongoing use. That’s not failure—that’s biology. "Are there side effects?" Yes. The most common are nausea, constipation, or bloating early on. Starting slow, staying hydrated, and eating smaller portions helps. Rare but serious risks exist, including pancreatitis. A good clinician will walk you through these carefully. "Will I lose muscle?" You can—unless you’re strength training and eating enough protein. We talk a lot about this at Wondercreek. Protecting lean muscle is critical. "Is this forever?" Not necessarily. Some women use these meds to reduce inflammation, restore insulin sensitivity, and break a cycle. Others stay on them longer due to underlying metabolic dysfunction. Every plan is individualized. Final Thoughts GLP-1 medications aren’t for everyone. But they are not cheating, shameful, or lazy. They’re a legitimate, science-based treatment for a serious, chronic condition. In my practice, we focus on healthspan—not just lifespans. That means preserving function, preventing disease, and helping you feel energized, sharp, and resilient for as long as possible. For some women, GLP-1 therapy is one of the most powerful tools we have to get there.
