Can Strength Training Reverse Bone Density Loss? A Study Says Yes.
For years, the prevailing belief in medicine and fitness has been that bone density loss is irreversible, especially in older women. You could slow the loss—maybe—but rebuilding it? That was considered impossible.
Until now.
In a remarkable study shared by longevity expert Dr. Peter Attia, a group of women in their mid-60s and beyond didn’t just maintain their bone mass—they built more of it. And they did it not with medication, but with heavy strength training.
Let’s break it down.
🧪 The Study: Rewriting the Rules on Aging Bones
“This is a study that was done with a group of women, all of whom were over 65 years old and all of whom had disease condition of very, very low bone density,” explains Dr. Attia. “They didn’t exercise beyond sort of like yoga and walking. So it’s not like they were inactive, but they’d never lifted weights.”
These women weren’t sedentary, but their routines were limited to light activity—the typical recommendations for aging adults. They had never engaged in structured resistance training.
They were randomized into two groups:
- One group continued with their usual light exercise
- Another began a program of “really, really heavy strength training”
💪 The Transformation: From Frail to Fierce
“These women who looked so frail by the end of the study are able to, in some cases, pick up their own body weight off the ground, do a deadlift with their own body weight,” Dr. Attia shares.
“They gain strength and they really do hardcore powerlifting exercises. Like they’re not, you know, holding the little two-pound dumbbells, doing curls—they’re doing squats, they’re doing deadlifts, all sorts of things.”
Women who were once told to “take it easy” were now lifting barbells, deadlifting body weight, and doing full-body compound movements. Their confidence and strength skyrocketed.
🦴 The Breakthrough: Increased Bone Density
Here’s the most astonishing part:
“By the end of this study, they defied something that we thought was possible,” Dr. Attia said. “We never thought it was possible to increase bone density… but amazingly in these women, based on the CT scans of their bones, they actually increased bone density.”
These women reversed bone loss, proving that aging doesn’t mean weakness—and strength is always possible.
🔬 Why Heavy Lifting Works for Bones
Bones respond to stress—just like muscles. When safely loaded through strength training, the body triggers a natural process called mechanotransduction, which stimulates bone remodeling and growth.
While walking and yoga have general health benefits, they don’t apply enough force to challenge the skeletal system the way heavy resistance training does.
Bottom line? To build stronger bones, you need to lift heavier loads under professional guidance.
