Osteoporosis Prevention: The Exercise Prescription Your Doctor Isn’t Giving You

By Dr. Emily Warren, DPT, credentialed McKenzie therapist, BoneFit-trained | Mindful Movement PT, Salt Lake City, UT

Being told to exercise for your bones can leave a lot unanswered: which movements, how much resistance and how to progress? We help you learn the skills and find a challenge that fits. A clear plan makes it easier to begin and keep going.

Progressive strength training is a valuable part of bone-health care. A clear plan should tell you what to practice, how to learn it well and when to progress. That is the gap we help you close through individual PT and coached Bone Builder classes.

This article covers the science of how bone responds to mechanical loading, why most exercise recommendations fall short, and exactly what type of training has been proven to build bone in clinical trials.

Make “exercise for your bones” specific enough to use

A recommendation to exercise is a good beginning, but it can leave practical questions: which movements, what resistance, and how should you progress? We help with that part. You practice the exercises with feedback and learn how they connect to strength, balance and the activities you want to keep doing.

How loading helps your bones

Bones respond to the loads placed on them. An effective exercise plan considers the type of activity, the challenge and how it progresses over time. Strength training gives us a way to adjust resistance and practice movements that matter in daily life. Bone-density response varies by skeletal site and the overall program, so we do not reduce your plan to a single bodyweight or strain threshold.

Progressive Resistance Training: The Foundation of Bone Building

Progressive resistance training is an important component of bone-health exercise. It lets us adjust the challenge over time while building strength and movement skills.

Why Heavy Matters

A heavier resistance can create a different challenge from a light weight repeated many times. We select that challenge for you through assessment and technique coaching rather than assume a particular dumbbell or barbell weight crosses a universal bone-building threshold.

LIFTMOR supports progressive, supervised loading as a useful option. It did not establish a single minimum weight or intensity that everyone must reach to benefit. We build the challenge around your technique, tolerance and goals.

The Exercises That Build Bone

Not all resistance exercises are equally effective for bone health. The most important exercises are compound movements that load the spine and hips, the sites most vulnerable to osteoporotic fracture:

Deadlifts

Deadlift variations teach a hip hinge and develop strength for lifting. They are one option within a broader program. We choose the version, range and resistance to fit your movement, fracture history and goals.

Squats

Back squats and front squats create axial loading through the spine and high compressive forces at the hip. The depth and load determine the magnitude of skeletal loading.

Overhead Press

Standing overhead press creates axial spinal loading and loads the upper extremity. It also challenges balance and core stability in the standing position.

Rows and Pulling Movements

Rows and other pulling exercises build back and shoulder strength and support movement control. They can be useful alongside the lifting, pressing and balance work chosen for your plan.

Impact Exercises: The Other Half of the Equation

While resistance training provides high-magnitude loading, impact exercises provide high-rate loading. Bone responds to both the magnitude and the rate at which force is applied. A rapid impact creates a different (and complementary) stimulus compared to a slow, heavy lift.

Effective Impact Exercises

• Jumping: Vertical jumps, broad jumps, jump squats. Ground reaction forces of 4-6x body weight.
• Drop landings: Stepping off a box and landing on both feet. Provides high-rate loading.
• Stomping: Deliberate, forceful foot strikes. Simple and accessible.
• Skipping and hopping: Unilateral impact loading for hip bone density.
• Stair bounding: Taking stairs with deliberate impact rather than absorbing force.

Choose the impact dose through assessment

We first decide whether impact work belongs in your plan. If it does, we teach a version that fits your balance, movement control, fracture history and medical guidance, then adjust the amount and progression to your response. A fixed jump count or a harder landing is not a substitute for that assessment.

What supervised loading in LIFTMOR teaches us

The LIFTMOR trial (Lifting Intervention For Training Muscle and Osteoporosis Rehabilitation) is the landmark study that validated high-intensity resistance training for postmenopausal women with low bone mass.

The Protocol

• Exercises: Deadlift, squat, overhead press, jumping chin-ups with drop landing
• Trial intensity: participants progressed to more than 85% of one-repetition maximum under supervision after learning the movements.
• Volume: 5 sets of 5 repetitions
• Frequency: 2 times per week, supervised
• Duration: 8 months
• Participants: Postmenopausal women with osteopenia or osteoporosis

The Results

LIFTMOR reported no fractures during its supervised intervention and one minor lower-back spasm. Screening, technique instruction and close supervision were part of the study. We use your assessment to decide what level of loading fits you.

The trial challenges the idea that low bone density always rules out challenging strength work. Screening, movement learning and close supervision helped the participants progress. We use that evidence to discuss an appropriate challenge for you.

Why a plan for progression matters

When to Start: Osteopenia Is the Window

Osteopenia (T-score between -1.0 and -2.5) is not a diagnosis that should cause panic, but it should cause action. This is the intervention window. This is when exercise has the greatest potential to prevent progression to osteoporosis and fracture.

Consider the trajectory:

• Normal bone density: Prevention is ideal but urgency is low
• Osteopenia: review bone health and exercise together with your medical clinician; fracture risk depends on more than the scan category.
• Osteoporosis: Exercise still works but must be more carefully programmed around fracture risk
• Post-fracture: Exercise remains essential but the approach must be even more conservative initially

An osteopenia result is a useful reason to review your exercise and overall fracture risk. It does not by itself show active bone loss or a fracture threshold. We help you take practical steps now, with a routine that fits your history and ability.

Getting Started Safely

Supervised progressive strength training can be a useful part of bone-health care. We begin with assessment and movement practice, then build the challenge when your technique, symptoms and readiness support it.

The Progression Path

1. Assessment: A BoneFit-trained physical therapist reviews your DEXA results, fracture risk, movement quality, and training history
2. Movement learning: practice the setup and technique with a manageable challenge before increasing resistance.
3. Load progression: increase resistance thoughtfully when control, response and assessment support it.
4. Progression: choose resistance with your clinician or coach and increase it when technique, symptoms and your assessment support the next step.
5. Maintenance: Continue training at high intensity with periodic testing and adjustment

Learning and progression take time, and the pace varies. We move forward when your technique, tolerance and assessment support it. LIFTMOR measured outcomes after eight months; we also track useful strength and movement changes along the way.

Who Should Seek Professional Guidance

While anyone can benefit from expert instruction, the following situations particularly warrant working with a specialized bone health physical therapist:

• Established osteoporosis (T-score below -2.5)
• History of fragility fracture
• Vertebral compression fractures
• No prior strength training experience
• Significant kyphosis or postural changes
• Balance impairments or fall history
• Uncertainty about which exercises are safe

Frequently Asked Questions

My doctor told me to avoid heavy lifting because of my osteoporosis. Is that wrong?

If you have been advised to avoid heavy lifting, bring that advice and the reasons behind it to your assessment. We can help clarify suitable options and coordinate with your medical clinician. Supervised strength work can offer a useful path when it fits your health history.

How does exercise compare to medication for bone density improvement?

Medication and exercise address different parts of bone health, and their results should not be compared as if percentages from different studies are interchangeable. Your prescriber guides medicine choices. We help with strength, balance, movement and a progressive exercise routine; appropriate medical treatment and training can belong in the same plan.

I am 70 years old. Is it too late to start strength training for my bones?

It is not too late. Research demonstrates that bone retains the ability to respond to mechanical loading throughout the lifespan. Studies have shown BMD improvements in women in their 70s and 80s with appropriate resistance training. Additionally, the fall prevention benefits of strength training (improved muscle strength, better balance, faster reaction times) become even more important with advancing age, as fall-related fractures are the primary clinical concern. The approach may need modification for age-related factors, but the principle remains the same: load the skeleton progressively above the mechanostat threshold. Starting under the guidance of a qualified professional ensures safety while maximizing benefit.

How often do I need to exercise to build bone, and can I ever stop?

Two strength sessions a week can provide a useful routine, as in the supervised LIFTMOR study. The amount of impact work, balance practice and independent training depends on your assessment and goals. We help you build a schedule you can maintain and adjust when your health or circumstances change. Bone Builder meets Tuesday and Thursday, noon–1 p.m.
