Did you know…
• 40–50% of older women have low bone density — and most don’t even know it.
• 80% of Americans with osteoporosis are women.
• With low bone density, you have a 50% chance of experiencing a fracture.
• 70% of all hip fractures happen in women — and here’s the scary part: 1 in 3 women who sustain a hip fracture die within a year.
Having higher bone density means stronger bones, fewer fractures, and a better quality of life as you age. Yes, on average, women live about six years longer than men — but their quality of life in those later years is often worse. Two-thirds of assisted living residents are women, largely because they can no longer perform daily tasks independently.
So why is that?
A major reason is frailty, osteoporosis, and injuries from falls — all of which lead to loss of independence and a sharp decline in quality of life.
Think about the women who are now in their 70s or older. When they were in their 30s and 40s — back in the 1980s — fitness culture was all about cardio, dieting, and being thin. Very few women picked up a barbell. Strength training wasn’t encouraged; being tiny was. Fast forward 40 years later, and many of those women now have no muscle, no strength, and very low bone density.
Women typically reach peak bone density between ages 25–30, and it begins to gradually decline around 35. The loss accelerates during perimenopause and menopause as estrogen levels drop.
By starting strength training early (ideally before 35) it helps you build a higher peak bone density so you have more to work with as you age.
But if you’re already in your 40s, 50s, or beyond — don’t worry, all is not lost.
A meta-analysis of 17 studies on women over 50 with osteoporosis found that lifting heavy weights (5–12 reps per set) at least three times per week for 40 minutes significantly improved bone density.

What works for building and maintaining bone density:
1. Strength training 2–3 times per week for at least 30 minutes, lifting heavy enough to reach near failure in the 5–12 rep range.
2. Jumping or plyometric movements 1–2 times per session.
3. Short-distance, high-intensity running (sprints or intervals).
4. Adequate protein intake — at least 0.8 grams per pound of body weight daily.
5. Vitamin D and calcium supplementation together — around 800 IU of Vitamin D and 700 mg of calcium per day.

What doesn’t work:
1. High-rep, low-load workouts like Pilates, yoga, or bootcamps that never bring you close to muscular failure.
2. Brisk walking (even with a weighted vest).
3. Long-distance running.
4. Low-protein diets.
5. Taking Vitamin D or calcium alone — they’re far more effective when combined.

Strong bones are your ticket to a better, more independent life as you age.
The solution? Strength train 2–3 times a week, challenge yourself with heavier weights, and include some plyometric movements.
