Strong bones are built, not inherited.
Osteopenia and osteoporosis are common in adults 60+, and progressive training modestly slows, halts, or partially reverses the underlying trajectory. What the research supports — and where its limits are — from a Spokane coaching studio built for adults over 60.
Osteopenia and osteoporosis describe a continuum of reduced bone mineral density, diagnosed by a T-score on a DXA scan. In US adults 50 and older, 12.6 percent have osteoporosis and 43.1 percent have low bone mass. For most of recent medical history the condition was framed as one-directional. Randomized trials over the past decade tell a more useful story: bone responds to load at any age, net gains are modest but real, and the right kind of training can halt or partially reverse the trajectory for many adults in their 60s and 70s. This page explains what the conditions are, what the research actually shows about slowing or reversing them, and where the evidence base ends.

What osteopenia and osteoporosis actually are
Both terms come from the same diagnostic measurement: a T-score from a dual-energy X-ray absorptiometry scan — DXA — which compares a person’s bone mineral density against the average for a healthy young adult. The World Health Organization defined the categories in 1994, and they have been the clinical standard since.
A T-score at or above negative one indicates normal bone density. A T-score between negative one and negative two-and-a-half is osteopenia — bone density below normal but not yet at the osteoporotic threshold. A T-score at or below negative two-and-a-half is osteoporosis. A T-score at or below negative two-and-a-half combined with a fragility fracture (a fracture from a fall at standing height or less) is classified as severe or established osteoporosis.
The scores are measured at specific anatomical sites, most commonly the lumbar spine (the low-back vertebrae) and the femoral neck (the part of the thigh bone that connects to the hip). Different sites can yield different scores on the same person; a woman may have osteopenia at the femoral neck and osteoporosis at the lumbar spine. Clinical decisions are made on the worse of the two.
A companion tool called FRAX integrates the T-score with clinical risk factors — age, sex, prior fracture, parental hip-fracture history, smoking, alcohol intake, corticosteroid use, rheumatoid arthritis, secondary osteoporosis — to estimate a 10-year probability of a major osteoporotic fracture. FRAX is used clinically to estimate fracture probability and inform decisions about pharmacologic treatment.
Neither osteopenia nor osteoporosis is a disease in the infectious or metabolic sense. Both are states — positions on a spectrum — and both are modifiable. What determines the direction of modification is the combination of hormonal state, nutrition, and mechanical loading. This page is about the third.
Why it matters
Low bone density is widespread in US adults. The National Center for Health Statistics reports that 12.6 percent of US adults aged 50 and older have osteoporosis and 43.1 percent have low bone mass. Prevalence rises steeply with age and is substantially higher in women: among women 65 and older, 27.1 percent meet the osteoporosis threshold, compared with 5.7 percent of men the same age.
More striking than the prevalence is how much of it is invisible. A 2025 analysis of NHANES data estimated that roughly 69 percent of US adults who meet the femoral-neck T-score threshold for osteoporosis are undiagnosed. In concrete terms: a reader of this page aged 60 or over may already have osteoporosis without knowing it; an adult child reading this on behalf of a parent may be looking at a condition that has never been measured; and a referring physician looking for patients to screen is looking at a very large pool, one the current primary-care workflow misses most of the time.
For women, the long trajectory is well documented. In the Study of Women’s Health Across the Nation, a multi-site longitudinal cohort, women reduced lumbar-spine bone mineral density by 10.6 percent and femoral-neck density by 9.1 percent across a 10-year window spanning menopause. Most of that change was concentrated in a narrow transmenopausal window of roughly 1.8 to 2.0 percent per year, slowing to 0.5 to 1.0 percent per year in the post-transmenopausal phase. A separate 25-year cohort study reported mean femoral-neck loss of about 10.1 percent over the full span.
For men the trajectory differs in rate and timing, not in responsiveness. Femoral-neck bone density reduces steadily in men without the menopausal inflection that women experience — a slower pace than the women’s transmenopausal window, but cumulative over decades. Osteoporosis in men is less common, diagnosed less often, and undertreated when found; excess mortality following a hip fracture is higher in men than in women, partly because men tend to present later. The training response is equivalent. The public conversation about bone is not.
The practical meaning of a low T-score is that a moment that would otherwise be a near-miss — tripping on a rug, catching a foot on a stair, missing a step off a curb — can convert into a fracture. The fall that fractures one 75-year-old’s hip is the fall another 75-year-old walks away from, stiff and bruised. Training changes which group a person is in. Of the fragility fractures that produce the greatest downstream harm, hip fracture carries a roughly 17 to 25 percent one-year mortality in contemporary cohorts, rising to roughly 40 percent in adults 80 and older. Only 40 to 60 percent of 1-year survivors recover pre-fracture mobility; 20 percent of survivors over 80 are in residential care a year later. Vertebral fractures change posture, gait, and breathing capacity, and often start a cascade of further changes. Training does not eliminate this risk, and no exercise trial is powered to measure fracture reduction. What training does is raise the floor beneath a fall: a body with more bone density, more muscle, and better balance is a body at which the same fall lands differently.
What the research shows about reversal
The evidence that structured training changes bone is strongest when training combines resistance work with impact loading. The effects are smaller than for muscle — net changes of roughly 1 to 4 percent at the lumbar spine and 0 to 2 percent at the femoral neck against control groups, across 6 to 12 months of intervention. These numbers are modest by muscle standards. They are also real, reproducible, and measurable using standard DXA equipment.
The flagship trial is LIFTMOR, published in 2018 by a research group at Griffith University in Australia. The team enrolled 101 postmenopausal women with osteopenia or osteoporosis, mean age 65, and randomized them to one of two programs: a supervised high-intensity resistance-and-impact arm (compound free-weight lifts at 80 to 85 percent of one-repetition maximum, five sets of five reps, twice per week, plus jumping chin-ups with drop landings) or a home-based low-intensity control. After 8 months, the trained group had gained 4.1 percent in lumbar-spine bone mineral density, 2.2 percent in femoral-neck density, and 7.3 percent in femoral-neck cortical thickness against the control group. Compliance with the supervised protocol was 92 percent. One minor adverse event was reported across the cohort.
The same research group followed with LIFTMOR-M in 2020, testing the protocol in 93 men with a mean age of 67. The results replicated: net lumbar-spine bone mineral density rose 3.2 percent and trochanteric bone mineral density rose 2.9 percent against control. Bone loads respond to training in men and women alike.
One piece of honesty is necessary before any of these numbers are used elsewhere. No exercise randomized controlled trial is currently powered to detect fracture reduction as a primary endpoint. The studies available measure bone mineral density, which is a strong but imperfect predictor of fracture risk — the kind of measurement statisticians call a surrogate outcome. The LIFTMOR trials reported zero training-related fractures; that is a safety signal, not proof of reduced fracture incidence in the general population. What the evidence supports is maintenance and modest improvement of bone density. A claim that exercise “prevents fractures” outstrips the current literature. A claim that exercise maintains or partially rebuilds bone density, under a well-designed program, fits what the trials actually measured.
The unresolved intensity debate
The literature contains a genuine, unresolved disagreement about how much load is needed to build bone density. The two positions deserve separate descriptions because serious researchers sit on each side, and because a program that serves adults 60+ needs to be able to answer for both.
A 2021 meta-analysis by the LIFTMOR research group analyzed 53 randomized trials in postmenopausal women and reported that at the lumbar spine, high-intensity exercise produced a greater pooled mean difference (+0.031 grams per square centimeter) than moderate (+0.012) or low-intensity (+0.010) alternatives. Their position: to maximally stimulate lumbar-spine bone mineral density, the evidence supports high load and high impact, delivered under expert supervision.
A 2023 network meta-analysis in Frontiers in Physiology, drawing on 19 randomized trials, reached a different conclusion. That group ranked moderate-intensity resistance training (65 to 80 percent of one-repetition maximum) superior to high-intensity on summary statistics for both lumbar-spine and femoral-neck bone density. A broader 2023 update by a separate research group reached similar conclusions on pooled averages: moderate loading appears comparable to high-intensity across the full published literature, not inferior. Their position: across the broader evidence, moderate loading delivers comparable bone mineral density outcomes without the biomechanical demands or supervision burden of the LIFTMOR protocol.
Both sides agree on the clinical translation. High-intensity resistance-and-impact training demands expert supervision, appropriate spine screening, and careful individualization — not every participant is a candidate for five-by-five deadlifts at 85 percent of one-repetition maximum. Moderate-intensity programs are a safer floor for beginners and for adults with vertebral-fracture history. A reasonable program moves through both: starts moderate, progresses toward higher intensity where coaching competency and individual readiness support it. The debate is about ceilings, not about whether training matters.
Major consensus documents converge on the direction even where they differ on intensity. The United Kingdom’s 2022 “Strong, Steady and Straight” consensus statement endorses progressive resistance training to near-maximal effort where safe, combined with impact and weight-bearing work and balance training, and specifies that adults with vertebral fracture can train under individualized modification rather than being excluded. The American College of Sports Medicine’s bone-specific position stand, last updated in 2004, remains the most recent US document on the topic and recommends weight-bearing and resistance exercise across the adult lifespan.
Three honest tensions
First, the intensity debate above. Unresolved on pooled averages, with credible researchers on both sides. A program should be able to deliver both and progress between them as the member’s readiness warrants.
Second, the fracture-endpoint gap already addressed: bone density is a surrogate, not the outcome patients most care about. Until a fracture-powered exercise trial is run, the case for exercise as fracture prevention remains indirect.
Third, the population-specificity issue. The LIFTMOR-family trials recruited community-dwelling adults without severe frailty, recent fractures, or contraindications. Translating high-intensity protocols to 80- and 90-year-old adults, or to adults with prior vertebral fractures, is a matter of individualized progression rather than protocol substitution. The evidence base is strongest in the 60s and 70s, and it thins with age and with clinical complexity.
Know where your bones actually are.
Most adults 60+ have never had a DXA scan and have no current measurement of their bone mineral density. The Strategy Session does not replace a DXA — that is a medical test ordered by a physician — but it produces the context. A 45-minute one-on-one appointment: a full health history, strength and balance testing, a short gait analysis, and a written plan you can keep whether you join or not. If you have had a DXA, bring the report — we can build your program around it. If you have not, the Strategy Session may surface questions worth raising with your physician, who is the right person to decide whether a DXA is indicated.

How Able Years addresses bone health
We are a coaching studio, not a clinic. Our approach to bone is the approach the research supports: supervised progressive resistance training, two to three sessions per week, with compound multi-joint lifts that load the spine, hip, and thigh together. Where individually appropriate and under coaching supervision, impact-loading elements — jumping, step training, controlled landings — are added, following the pattern that has produced the largest measured effects on bone in the published literature.
Progression is individualized. A member starting with no recent training history begins at moderate intensity and advances toward higher loading only after movement patterns, joint response, and confidence support it. A member with a history of vertebral fracture is modified according to the United Kingdom consensus framework — progressive resistance can continue, with the specific movements and loading patterns individualized to protect the spine.
Balance and functional-task training are integrated into every session. Bone density is one pillar of fall-related fracture risk; the likelihood of falling in the first place is the other. A program serious about bone addresses both.
Every new member begins with a one-on-one Strategy Session. Classes are capped at 10 people. Every coach is certified through the American Council on Exercise and the Functional Aging Institute. Our programming is built in collaboration with Robert Linkul, a nationally known specialist in training for adults over 60. Read more about our strength training approach for adults 60+ in Spokane.
What we do not claim: fracture reduction in our own members. No exercise trial, including the LIFTMOR family, is currently powered to measure fractures as a primary outcome. The literature measures bone density, which is what the training changes. Fractures are what the training is hoped to reduce downstream; that claim belongs to the next generation of trials, not to any studio today. What we can say is what the trials actually measured: supervised progressive resistance training, with impact where appropriate, maintains and modestly improves bone mineral density in adults with osteopenia and osteoporosis.
Common questions about osteopenia and osteoporosis
What’s the difference between osteopenia and osteoporosis?
Both are diagnosed from the same measurement — a T-score on a DXA scan, which compares bone mineral density to a healthy young-adult reference. A T-score between negative one and negative two-and-a-half is osteopenia: bone density is below normal but has not crossed the clinical threshold. A T-score at or below negative two-and-a-half is osteoporosis. A T-score at or below negative two-and-a-half combined with a fragility fracture is severe or established osteoporosis. The practical meaning: osteopenia is a modifiable warning; osteoporosis is the point at which fracture risk rises sharply enough that most physicians begin considering pharmacologic treatment. Progressive training is part of the response at either level.
Do I need a DXA scan before starting?
A DXA is useful — it tells you where on the T-score spectrum you are — but it is not a gatekeeper to training. Most research trials in this area recruited participants based on prior DXA results, but the protocols themselves do not require a current scan to begin. If you have had a DXA in the last few years, bring the report to the Strategy Session and we can build your program around it. If you have not, we may suggest you discuss one with your physician, especially if you are a woman past menopause, an adult over 70, or someone with a prior fragility fracture. Either way, training can start before the results are back.
Can exercise actually rebuild bone, or only slow the loss?
Both, depending on the program and the participant. The published effect sizes are modest: net increases of roughly 1 to 4 percent at the lumbar spine and 0 to 2 percent at the femoral neck against control groups, across 6 to 12 months of progressive resistance training. For participants at lower baselines, that can mean crossing back above the osteopenia-to-osteoporosis threshold. For participants at higher baselines, the effect is usually maintenance rather than gain — which, against an age-related trajectory of continued bone loss, is itself a meaningful outcome.
Is heavy lifting safe if I already have osteoporosis?
In most cases, yes. Several of the highest-quality trials in this area specifically enrolled women with osteopenia and osteoporosis and had them performing supervised heavy compound lifts. The LIFTMOR trial reported one minor adverse event across 101 participants trained at 80 to 85 percent of one-repetition maximum for 8 months. The variables that matter are supervision and individualization. Heavy lifting with poor technique or without spine screening is not safe. Heavy lifting with competent coaching, appropriate progression, and screening for vertebral-fracture history is not only safe but has produced the largest measured bone responses in the literature.
Should I avoid certain movements if I have a vertebral fracture in my history?
Modify rather than avoid. The United Kingdom’s 2022 consensus statement on physical activity and osteoporosis is explicit that adults with vertebral fracture can continue progressive resistance training, with specific movements and loading patterns individualized to the person. Movements that load the spine into deep forward flexion are commonly modified or removed. Movements that load the spine in neutral position — squats, deadlifts performed with a supported torso, overhead pressing — are often retained, progressed more gradually, and supervised closely. The right coach adapts the program to the spine in the room.
How long before bone density changes are measurable?
Longer than for muscle. Strength gains are detectable at six to eight weeks; bone-density changes require 6 to 12 months of consistent training before DXA can measure them reliably. This is one reason short-term participation is a poor test of whether a bone program is working. The LIFTMOR trial ran for 8 months. Most meta-analyses pool trials of 6 to 12 months. A member committing to bone outcomes should plan for at least that window, with training continuing indefinitely to maintain any gains.
I’m on medication for bone density. Should I still do this?
Medication and training are not mutually exclusive — they act through different mechanisms and can be complementary. Training produces benefits that medication does not: increases in muscle strength, balance, posture, and functional capacity that independently reduce fall risk and improve daily function. Medication produces benefits that training does not, at least not at the same magnitudes: stronger pharmacologic effects on bone remodeling. The research supports using both where appropriate. Questions about your specific medication regimen are best discussed with the physician who prescribed it. Training works alongside medical treatment, not in opposition to it.
