If your phone is cheering you on for hitting a step goal, you are not alone. Walking has become the go-to “do something healthy” habit because it is free, accessible, and it genuinely works for mood, blood pressure, and overall fitness.
But a message from cardiovascular surgeon Jeremy London, MD is landing with a lot of people for a different reason. His point is simple and a bit uncomfortable. Walking is a terrific baseline, but it is not the same thing as a bone-building plan, especially for women in midlife.
Walking is still a win
London put it bluntly in a recent post, saying, “Walking does not build strong bones, and women in midlife especially need to hear this.” The reminder matters because walking does a lot of heavy lifting for general health, from metabolic markers to weight maintenance.
The problem is that bones do not “care” about your step count the way your heart does. For the most part, walking does not provide enough mechanical challenge to push bone mineral density upward, which is why London warns, “Walking alone does not significantly build bone mineral density.”
Bones respond to stress, not just movement
Bone is living tissue that is constantly being broken down and rebuilt. When the body senses a bigger load, it adapts by reinforcing the structure, much like thickening a well-used callus over time.
That “signal” tends to come from impact and from muscles pulling hard on bone during resistance work. In practical terms, the skeleton gets a stronger message from squats, deadlifts, loaded carries, and step-ups than it does from a relaxed stroll around the block.
Does that mean you should stop walking? Not at all. It means you should think of walking as the aerobic foundation, then add a separate layer designed to protect your hips and spine.
Why midlife is a turning point for women
Around the menopausal transition, estrogen levels drop and bone loss can accelerate. The American College of Obstetricians and Gynecologists notes that women lose bone more rapidly during the first several years after menopause, which helps explain why the risk picture can change so fast in your 40s and 50s.
The scale of the issue is easy to miss because low bone density is often silent until the first fracture. In U.S. survey data from 2017 to 2018, the CDC estimated osteoporosis affected 12.6 percent of adults age 50 and older, while low bone mass affected 43.1 percent. Women carry a disproportionate share of that burden.
Zoom out, and it is not just a women’s issue or an aging issue. The World Health Organization estimates about 1.71 billion people worldwide live with musculoskeletal conditions, a category that includes osteoporosis and sarcopenia, the age-related loss of muscle that can make falls more likely.
What the research says about resistance training
Resistance training is not a trendy “extra” for strong people at the gym. It is one of the most consistent non-drug strategies researchers study for protecting or improving bone mineral density, especially in postmenopausal women.
A 2026 systematic review and network meta-analysis in the Journal of Sport and Health Science compared different exercise approaches and found that programs combining resistance training with mind-body exercise such as yoga, tai chi, or Pilates produced the most consistent improvements across several bone sites. It also found a familiar theme in exercise science, which is that longer programs, at least a year, tended to deliver more stable results.
One nuance worth keeping in mind is that no single workout is magic. Aerobic exercise can have site-specific benefits, and walking can help with balance, blood sugar, and the daily habit of moving, but it may not be enough if your main goal is building bone strength.
A realistic bone-building routine you can stick with
Public health guidance already points people in this direction. The CDC recommends adults get at least 150 minutes of moderate-intensity aerobic activity per week, plus muscle-strengthening activity on two or more days per week that hits all major muscle groups.
For bone, intensity and progression matter. That does not mean everyone needs a barbell, but it does mean the last few reps should feel challenging, and the weight or difficulty should gradually increase as you get stronger. Think of it like paying into a “bone and muscle retirement account” a little at a time.
If you are starting from scratch, two full-body sessions per week is a solid beginning. Build around a few basic patterns, like a squat or sit-to-stand, a hinge such as a light deadlift, a push, a pull, and a carry, then keep walking on the days in between for circulation and stress relief.
Safety, screening, and the nutrients bones need
If you have already been told you have osteopenia or osteoporosis, or if fractures run in your family, talk with a clinician before adding impact or heavy lifting. Form, supervision, and smart exercise selection matter more than bravado, and the goal is to get stronger without inviting injury.
Food and recovery count too. The NIH Office of Dietary Supplements lists the calcium recommended dietary allowance for women over 50 at 1,200 milligrams per day, and vitamin D needs at 600 IU per day for adults up to age 70 and 800 IU per day for adults 71 and older.
At the end of the day, the most protective plan is a mix, not a single habit. Keep walking because it helps nearly everything, then add progressive strength work so your bones get the message they have been waiting for.
