Menopause Is More Than Hot Flashes — What Happens to Muscle & Bone? We talk about hot flashes, periods stopping and mood changes when we talk about menopause. But while I was researching this week, I kept coming back to a different question: Why aren’t we talking to women earlier about what can happen to their muscle, strength and bones? And then I found something that surprised me even more. We actually don’t have nearly as much high-quality exercise research during the menopause transition as I assumed we did. Perimenopause isn’t simply estrogen slowly sliding downward in a perfectly straight line. Hormonal patterns fluctuate through the transition, and the menopause transition overlaps with an age when changes in body composition, muscle and bone are already occurring. Bone deserves particular attention because estrogen has an important role in regulating bone remodeling. Around menopause, bone resorption can outpace formation. Muscle is a little more complicated. Menopause, aging, physical activity, nutrition and other factors overlap, which makes it difficult to say: “This amount of muscle loss happened specifically because estrogen declined.” That’s an important distinction. WHY does this matter? Think about your body like a retirement account. You don’t wait until retirement to start saving. Muscle, strength and bone are similar. What you build and preserve in your 40s and 50s affects the physical reserve you’re carrying into your 60s, 70s and 80s. We’re not training simply because we want our arms to look good. We’re building the ability to: get off the floor, carry groceries, climb stairs, catch ourselves when we trip, tolerate a fall better, maintain independence and keep doing the things we actually enjoy. That’s a completely different reason to lift. The research gap I wasn’t expecting A 2025 systematic review asked a very specific question: Can exercise prevent bone and muscle loss during peri- and early postmenopause? Researchers searched five major databases for randomized controlled trials involving women ages 45–60 who were perimenopausal or early postmenopausal.

If somebody had told you at 30 that muscle and bone were something you were building for your 70-year-old self, would it have changed how you trained?
