Most patients leave their rheumatologist or endocrinologist with a DEXA result, a prescription, and a handout that says "weight-bearing exercise." Almost none of them end up in a program that actually moves the needle on bone density.
I've been working with osteoporosis and osteopenia patients for years, and the pattern is consistent: by the time someone lands in my clinic, they've had low bone density for a decade, been told repeatedly to "stay active," and have never once been introduced to the specific type of loading their skeleton actually needs.
This isn't a criticism of prescribing physicians — it's a structural gap in how we deliver care. Exercise medicine for bone health is a specialty, and the evidence base has gotten precise enough that "weight-bearing activity" is no longer a sufficient recommendation.
What the Research Actually Requires
The skeleton responds to mechanical loading through a well-characterized pathway: strain on the bone matrix triggers osteocyte signaling, which drives osteoblast activity, which deposits new bone. The problem is that this pathway has thresholds.
Walking — the most commonly recommended "weight-bearing exercise" — generates approximately 1.0–1.2× body weight in ground reaction force. That's below the strain threshold needed to stimulate meaningful osteogenesis in adults with established bone loss. Swimming and cycling, both frequently recommended for joint protection, generate essentially no axial loading at all.
To actually stimulate bone formation, the evidence points to two specific inputs: high-load resistance training at or above 80% of one-rep maximum, and moderate-to-high impact loading (jumping, stomping, hopping) that generates meaningful ground reaction forces. These aren't comfortable recommendations for the average GP to make to a 68-year-old with a T-score of −2.5. But they are what works.
The gap isn't in the evidence. The gap is between what the evidence says and what patients are actually doing on Tuesday mornings.
Why "Exercise" Recommendations Fail in Practice
The specificity problem
General exercise guidance doesn't translate to clinical outcomes because bone loading is dose-dependent. A patient who walks 30 minutes a day and does a Pilates class twice a week is moving — but their skeleton is not receiving the stimulus it needs. Without specificity (load magnitude, velocity, skeletal site), the recommendation is physiologically inert for bone purposes.
The fear-avoidance barrier
Patients with osteoporosis are frequently afraid of fracture — and reasonably so. When a physician says "be careful" or "avoid falls," patients often interpret this as "avoid loading." The result is a population that moves less and loses bone faster. Supervised, progressive loading programs are the only evidence-based way to address both the bone density deficit and the movement fear simultaneously.
The referral destination problem
Even when a physician wants to refer to exercise, where do they send the patient? A general fitness trainer isn't equipped to manage someone on Prolia or post-vertebral fracture. A standard PT clinic may focus on pain and function without implementing a bone-loading protocol. The infrastructure for delivering evidence-based exercise medicine for osteoporosis has simply not existed in most communities — until now.
The Onero™ Protocol
Onero is a licensed, evidence-based bone-loading program developed from the LIFTMOR trial — the highest-quality RCT on exercise for osteoporosis to date. Key parameters:
- Frequency: Twice weekly, 30–45 minutes per session
- Loading intensity: Progressive to ≥80% 1RM across compound movements (deadlift, squat, overhead press)
- Impact component: Structured jump training to generate high ground reaction forces at the hip and spine
- Supervision: Small-group, clinician-supervised — every session
- Safety record: The LIFTMOR trial reported zero serious adverse events in the high-intensity group
- Outcomes: Significant improvements in lumbar spine and femoral neck BMD; improvements in balance, strength, and functional capacity
Phyzique Multisport is one of a small number of licensed Onero™ providers in San Diego County, operating under the Better Bones Rx clinical umbrella.
What a Referral Looks Like
The patients who benefit most from Onero are those you're already seeing: postmenopausal women with osteopenia or osteoporosis, patients on or transitioning off anabolic therapy (Teriparatide, Romosozumab), patients who've had a fragility fracture and need structured reloading, and anyone for whom you've written "exercise" on a prescription pad without a clear destination.
A warm referral — even a brief note in the after-visit summary — is enough. Patients arrive, undergo an intake and movement screen, are cleared for progressive loading, and begin the program within the week. I send brief clinical updates back when meaningful changes occur.
This is the referral pathway that was missing. I built it because I kept seeing the same patient: well-managed medically, undertreated physically, losing ground one quiet year at a time.
