How long does it really take to build bone?


Hi Reader,

While I sit and wait for my retinal tear to heal (2 weeks post-surgery visit tomorrow!), I’ve had time to reflect on some of the most common questions I hear from you.

Here’s one of the most frequent:

"If I’m lifting weights and doing the right exercises, how long before my bones get stronger?"

Let’s break it down together.

✅ The Good News:

You can build stronger bones after menopause.
But bones respond more slowly than muscles, so we need to give them time.

It typically takes 6 to 12 months of consistent exercise to see meaningful changes on a DEXA scan.
👉 (This is why DEXA scans only need to be done every 1–2 years—because real change takes time.)

But here’s the exciting part:
Most women feel stronger, more stable, and confident within 4–6 weeks of targeted movement.
And that’s a big win!

You’re improving:

  • ✅ Balance
  • ✅ Coordination
  • ✅ Posture
  • ✅ Fall prevention

What the Research Shows:

🔹 The LIFTMOR study found that two sessions a week of high-intensity resistance and impact training improved bone density in about 8 months.

🔹 A 2015 meta-analysis by Zhao et al. confirmed that resistance training—especially when combined with impact loading—improved bone mineral density at the most common fracture sites (spine and femoral neck).

🔹 A 2021 meta-analysis by Kistler-Fischbacher et al. showed that higher-intensity training leads to better bone outcomes, without increasing injury risk.

The takeaway?
You don’t have to be afraid to lift heavier.
Challenging your bones—safely and progressively—is exactly what helps them grow stronger.
Bone loves consistency, challenge, and time.

💪 So, What Should You Expect?

If you're doing the right kind of movement:

  • Feel stronger in 1 month
  • 📈 See measurable bone gains in 6–12 months
  • 🧬 Support your progress with protein, Vitamin D, rest, and consistency

Even 2–3 strength-focused sessions per week can make a big difference.

I built my Strong Women, Strong Bones program around this research.
It includes:

  • ✅ Free weights
  • ✅ Balance-based yoga
  • ✅ Evidence-based progressions
  • ✅ A dose of fun—with a supportive community

🧡 My next Strong Women, Strong Bones program begins this fall. Get the details and add yourself to the waitlist here.

As always Reader, I’m so glad you’re here—learning, asking thoughtful questions, and getting stronger with me.

Hi Reader, Last week, I had a cortisone shot in my left thumb CMC joint (the small joint at the base of the thumb). It's used in daily activities like opening jars and closing resealable bags (the worst), tying shoes, and holding a golf club. If you have arthritis in this joint, you know exactly what I am talking about. The pain had become hard to ignore, especially as I spent more time at the driving range⛳. After breaking my wrist last summer, follow-up X-rays confirmed what I already...

Hi Reader, Welcome to July Strong Women! Things around here are shifting with my husband newly retired,— I’ve been reflecting on what consistency looks like this season. Whether you’ve recently retired, work part-time, volunteer, or are navigating the quiet of an empty nest, this thought might sound familiar: "Now that I have more time, how do I actually stay consistent with exercise?" It might sound ironic, but having more flexibility can actually make it harder to build and stick to a...

Hi Reader, If you are new here, welcome! Last week, I sent an email with the results of my DEXA scan T-scores . This week, I want to take a closer look at another part of the report. It may be part of your DEXA report as well. Let's look at and interpret the TBS scores. What is TBS?TBS stands for trabecular bone score. It is a way to assess the quality of your bone structure, not just the density. The T-score tells us about the density of our bone, but the TBS numbers provide insight into the...
