What Is OsteoStrong?
OsteoStrong is a wellness program centered around a series of four specialized machines, known as the Spectrum System, that use a method called osteogenic loading. The process involves brief, high-impact emulation exercises performed under the supervision of a trained technician.
The Theory Behind the Technology
Based on Wolff's Law, which states that bone adapts to the loads placed upon it, OsteoStrong aims to stimulate bone growth by applying high axial compression forces. A single weekly session, lasting 10-20 minutes, is recommended to trigger this natural adaptive response. The appeal lies in achieving the benefits of high-impact activity without the associated risks of heavy lifting.
The Claims vs. The Clinical Evidence
OsteoStrong's marketing has promoted it as an effective, evidence-based program for improving bone density and strength. However, recent independent scientific findings have challenged these claims.
Scrutiny of the 2025 Studies
- Conflicting Results: The first clinical trial, published in February 2025, showed no statistically significant improvement in bone mineral density (BMD) or trabecular bone score (TBS) for participants using OsteoStrong alone. Improvements were only noted in groups also taking osteoporosis medication, with no added benefit from the OsteoStrong program.
- Methodological Flaws: An independent review led by Dr. Lora Giangregorio identified numerous shortcomings in the company-funded 2025 study, including issues with transparency, risk of bias, and poor statistical analysis.
- Lack of Evidence: A subsequent scoping review in July 2025 concluded that it is not possible to draw meaningful conclusions about OsteoStrong's efficacy or effectiveness based on the published research to date. A later September 2025 study also reported no improvements in BMD over 8 months.
OsteoStrong vs. Traditional Resistance Training
For building long-term strength and muscle mass, most experts still recommend traditional resistance training over OsteoStrong. The table below offers a direct comparison:
| Feature | OsteoStrong | Traditional Weightlifting |
|---|---|---|
| Time Commitment | Short, weekly sessions (10-20 mins) | Longer, more frequent sessions (e.g., 30+ mins, multiple times per week) |
| Effect on Bone | Claims to provide high impact emulation to stimulate bone growth | Proven method to increase bone density via consistent, progressive loading |
| Effect on Muscle | Focuses on fast-twitch fibers, not significant muscle mass | Builds overall muscle strength and mass, improves tone |
| Weight Loss | Minimal impact; does not burn many calories | Effective for calorie expenditure and metabolism boost |
| Accessibility & Cost | Can be expensive ($150-$300+ per month), requires franchise access | Cheaper, more accessible options (e.g., home weights, affordable gym memberships) |
| Comprehensive Fitness | Must be supplemented with other cardio and strength exercises | Offers a more comprehensive full-body workout |
For most individuals who can tolerate weight lifting, resistance training offers a more comprehensive and robust approach to overall fitness and bone health. However, OsteoStrong may have a niche for those who cannot perform traditional lifting due to injury or condition.

Potential Risks and Adverse Events
Independent research raises concerns about OsteoStrong's safety reporting. While some members report improvements, adverse events have been noted.
- Insufficient Data: Studies have been criticized for inadequate reporting of side effects.
- Reported Discomfort: Minor adverse events observed in research included knee, shoulder, and back discomfort during or after sessions.
- Potential for Serious Injury: One older study mentioned a compression fracture in a client, though safety information is limited.
It is essential to consult with your physician before starting any new wellness program, especially if you have existing health issues like osteoporosis.
Understanding the Costs and Commitment
Membership costs for OsteoStrong vary significantly by franchise location, with prices ranging from $150 to $300+ per month. This cost is often for just the basic weekly session on the machines. Some centers offer additional modalities like red light therapy or compression boots for an extra fee.
The time commitment is minimal, with sessions lasting only 10-20 minutes, once per week. However, critics point out that this doesn't offer the comprehensive benefits of a full workout routine.
Conclusion: Making an Informed Decision
Is OsteoStrong a good program? The answer is nuanced and depends on individual circumstances.
For those seeking a non-pharmaceutical, low-impact method to potentially improve bone health and who can afford the cost, it may be an option, but with significant caution. Testimonials highlight positive results for some users, particularly in relation to balance and reduced pain.
However, independent scientific reviews have consistently failed to substantiate the program's claims regarding significant increases in bone density, especially when used alone. The scientific scrutiny and concerns about research bias suggest that the marketing claims may be exaggerated.
For many, especially those who are able to engage in traditional exercise, more proven and affordable alternatives like consistent resistance training and plyometrics offer a more comprehensive path to long-term bone and muscle health. Always consult a healthcare professional before making a decision.
