Osteoporosis is one of the most common conditions walking through the doors of Pilates studios in Australia. It is also one of the most under-prepared for. Many instructors know to avoid certain movements but are less clear on why, and even less clear on what to do instead.
This post gives you a working framework for making safer, more informed movement choices for clients with osteoporosis, including a group class template you can adapt straight away.
Understanding the Risk in Plain Terms
Osteoporosis reduces bone density, which increases fracture risk. But not all movement increases that risk equally. Understanding which movements and loading patterns are problematic, and why, is what allows you to teach with confidence rather than avoidance.
Where Fractures Tend to Occur
The most common osteoporotic fracture sites are the vertebral bodies of the thoracic and lumbar spine, the hip, and the wrist. Vertebral fractures are particularly relevant in Pilates because they can occur under relatively modest loads when the spine is in flexion, and compression is applied. This is the primary reason spinal flexion under load is the movement pattern most commonly associated with fracture risk in this population.
The International Osteoporosis Foundation provides comprehensive guidance on fracture risk and the role of exercise in prevention and management. Their specific exercise guidelines for individuals with osteoporosis are worth reading in full if you are regularly teaching this population.
What Actually Increases Fracture Risk
Loaded spinal flexion is the primary concern. This means exercises that round the spine forward under load, particularly in the thoracic and lumbar regions. High-impact activities that involve a falling risk are also relevant. Twisting under load, particularly in the lumbar spine, warrants care. What does not inherently increase fracture risk is movement itself. Appropriate, well-designed exercise is one of the most evidence-supported interventions for bone health. The Australian Government Department of Health consistently supports exercise as a key strategy in osteoporosis prevention and management.
The Difference Between Osteopenia and Osteoporosis
Osteopenia describes reduced bone density that has not yet reached the diagnostic threshold for osteoporosis. The movement considerations are similar, but the fracture risk is lower. Clients with osteopenia can generally tolerate a broader range of movement than those with established osteoporosis, particularly if there is no history of fracture. Ask your clients which diagnosis applies and whether they have had any fractures. That information changes your programming significantly.
Movement Patterns Worth Rethinking
This is not a list of exercises to ban. It is a list of patterns to be thoughtful about, particularly when load, range, and speed are involved.
Loaded Spinal Flexion
Exercises that take the spine into forward flexion under load are the highest priority modification for clients with osteoporosis. This includes Rolling exercises like Rolling Like a Ball and roll-ups in their full-loaded form, the Hundred with the head and shoulders lifted, and legs extended at a low angle, and any exercise that combines trunk flexion with hip flexor load. The compression forces on the anterior vertebral bodies in these positions can exceed safe thresholds for clients with reduced bone density.
This does not mean never flexing the spine. It means being specific about when, how much, and with what load.
Deep Rotation Under Load
Loaded rotation in the lumbar spine, particularly at end range, warrants care. The Saw and deep Spine Twist variations that take the thoracic and lumbar spine into combined flexion and rotation simultaneously are the exercises most worth modifying. Thoracic rotation with a stable, supported pelvis is generally safer and can still be a useful component of a class for this population.
High-Impact and Falling-Risk Activities
While less directly relevant to a Pilates context, it is worth knowing that any activity with a significant fall risk warrants extra caution in clients with osteoporosis. Balance work in standing is actually beneficial for this population, but it should be supervised and supported until the client has demonstrated adequate stability. Unsupported single-leg balance near the edge of a Reformer, for example, is a different risk profile from supported single-leg work at a wall or barre.
Safer Options and Progressions
For every movement pattern that needs rethinking, there is a way to achieve a similar training goal without the associated risk. Here is how that works in practice.
Replace Loaded Flexion With Supported or Unloaded Alternatives
The Chest Lift can remain in the repertoire when the head and shoulders are supported by the hands and the load through the anterior spine is managed carefully. Pelvic Curl in neutral to slight posterior tilt works the abdominals without the full flexion demand of a Roll Up. Knee Folds and inner unit activation work in supine, building abdominal function without placing the spine in a loaded flexion position.
Use an Extension to Balance the Programme
Thoracic extension exercises, including Swan Prep in prone, a supported Dart, and gentle thoracic extension over a rolled towel, are not only safe for most clients with osteoporosis but also actively beneficial. Extension loading on the posterior vertebral elements is well tolerated and supports posture in a population that commonly presents with increased thoracic kyphosis. Make extension work a deliberate component of every class rather than an afterthought.
Prioritise Axial Loading Through the Spine
Standing and seated exercises that load the spine through its long axis, walking, gentle squatting patterns, and standing Pilates work, provide the mechanical stimulus that supports bone density without the compressive risk of loaded flexion. The International Osteoporosis Foundation’s exercise guidance specifically identifies weight-bearing and resistance exercise as the most effective modalities for maintaining bone mineral density.
Keep the Reformer in the Toolkit
The Reformer is often useful for this population because spring resistance provides load through controlled, supported positions. Footwork builds lower limb and hip strength in a supine, supported position. Chest Expansion builds posterior shoulder and thoracic strength. Rowing variations, modified to avoid deep forward flexion, develop scapular stability and posterior chain strength. The key is selecting exercises that load the right structures without placing the spine in vulnerable positions.
A Group Class Template for Clients With Osteoporosis
This template is designed to work across a mixed group where some clients have osteoporosis, and others do not. It builds bone-supportive exercise into the session without requiring a separate class.
Warm-up (10 Minutes)
Breathing in sitting or standing, focus on thoracic expansion. Gentle head and neck movements. Shoulder circles and scapular setting. Standing calf raises near a wall for balance support. Pelvic tilts in standing to establish neutral.
Skill and Strength (25 Minutes)
Pelvic Curl series in supine, no loaded flexion beyond a comfortable range. Side-lying series: Side Kick Front Back, Side Kick Up Down, clam variations for hip strength. Prone series: Dart, Swan Prep, single-arm reach for thoracic extension and posterior chain loading. Standing series near a barre or wall: single-leg balance with support, small squats, and standing hip extension.
Integration and Cool-Down (10 Minutes)
Seated thoracic rotation in a neutral spine, not combined with flexion. Seated hip stretches. Supine breathing with ribcage awareness. Gentle constructive rest.

When to Refer Out
Knowing when to bring in additional support is as important as knowing how to modify.
History of Vertebral Fracture
Clients who have already sustained a vertebral fracture require a more conservative approach than those who have osteoporosis without a fracture history. A physiotherapy assessment before starting or continuing a Pilates programme is strongly advisable in this case. The assessment helps establish what loading is appropriate for the current presentation and identifies any postural or movement compensations that have developed as a result of the fracture.
Acute or Worsening Back Pain
Back pain that is new, worsening, or accompanied by other symptoms in a client with known osteoporosis warrants prompt medical assessment. Vertebral compression fractures can occur without a significant traumatic event and may initially present as back pain without an obvious cause. Do not assume a familiar pain presentation in this population. Refer early.
Uncertainty About Safe Loading
If you are unsure what is appropriate for a specific client’s presentation, refer or consult before proceeding. A physiotherapist or exercise physiologist with experience in osteoporosis management can provide loading parameters and exercise guidelines that make your Pilates programming more precise and confident. Building those referral relationships proactively is one of the markers of a well-developed teaching practice.
FAQs
Can clients with osteoporosis do Pilates at all?
Yes. Appropriate, well-designed Pilates is beneficial for clients with osteoporosis. The evidence supports resistance and weight-bearing exercise for bone health. The key is knowing which movements to modify and which to prioritise, which is exactly what this post covers.
Is Reformer Pilates safer than mat for this population?
Not inherently. Both can be safe, and both can be problematic depending on exercise selection. The Reformer offers useful loading options through supported, controlled positions. Mat work offers weight-bearing and extension exercises that are difficult to replicate on the Reformer. A well-designed programme for clients with osteoporosis often uses both.
Should I ask every new client about bone density?
Yes. Bone density and fracture history are relevant to how you programme, and many clients do not volunteer the information unless asked. A thorough intake process that includes questions about diagnosed conditions, medications, and fracture history gives you what you need to make safe decisions from the first session.
Are there exercises I should never do with a client with osteoporosis?
Avoid loaded spinal flexion, particularly Roll Ups, Rolling Like a Ball, and the Hundred with legs at a low angle and head lifted, in clients with established osteoporosis or fracture history. Beyond that, the answer is usually about how an exercise is performed rather than whether it is performed. Modifications that reduce load, range, or compressive force can make many exercises accessible that would otherwise be contraindicated.
How do I manage a group class where only some clients have osteoporosis?
Design the class with the safer options as your standard and offer challenge progressions for clients who are working at a higher level. This is the same principle that applies to any mixed-ability group. When the baseline of the class is appropriate for your most vulnerable client, you can layer in a challenge for others without compromising safety. The group class template above is built on this principle.
