How to find a trainer who understands older bodies
Most personal trainers are trained on young, healthy bodies. They do not understand osteoarthritis, post-surgical protocols, or chronic pain. Here is what to look for and what questions to ask.


The average personal trainer in the UK is 31 years old. Their qualification taught them to work with healthy adults between 18 and 40. Their practical experience is largely with clients who have no injuries, no chronic conditions, and no medications that affect exercise response.
If you are over 55, this matters.
Key takeaways
1. Most personal training certifications do not adequately cover age-related conditions like osteoarthritis, osteoporosis, or post-surgical rehabilitation.
2. A trainer who communicates with your physiotherapist and other practitioners produces significantly better outcomes than one who works alone.
3. The right trainer for your body is not the one with the best physique or the most Instagram followers. It is the one who understands your conditions, communicates with your healthcare team, and adjusts your programme based on evidence.
The qualification gap
The most common personal training qualifications in the UK are CIMSPA Level 2 and Level 3. These cover anatomy, physiology, exercise programming, and client communication. They do not cover clinical populations in depth.
A 2016 study in the Journal of Aging and Physical Activity surveyed personal trainers working with older adults and found that only 28 percent had received any formal training in age-related conditions. The majority reported feeling underqualified to work with clients who had osteoarthritis, osteoporosis, or chronic pain (Hawley-Hague et al., Journal of Aging and Physical Activity, 2016).
This does not mean young trainers cannot be excellent. It means the standard qualification pathway does not prepare them for the complexities of an older body.
Our Pilates teacher Sofia explains: "When I trained in the classical Pilates method, we barely covered how to modify for a client with a hip replacement or spinal stenosis. I had to seek out specialist training independently. Most trainers do not do that."
What to look for
There are specific markers that separate a trainer equipped for older adults from one who is not.
Relevant additional qualifications. Look for CIMSPA Level 4 qualifications in exercise referral, GP referral, or specialist populations. NASM Corrective Exercise Specialist or Senior Fitness Specialist certifications are also relevant. A degree in sports science, exercise physiology, or physiotherapy provides a stronger clinical foundation.
Experience with your age group. Ask directly: how many clients over 55 do you currently work with? What conditions have you worked around? A trainer who has spent five years working with 55 to 75 year olds will have encountered osteoarthritis, joint replacements, chronic back pain, balance issues, and post-surgical recovery many times. That experience cannot be replaced by a qualification alone.
Understanding of common medications. Beta-blockers affect heart rate response to exercise. Blood thinners affect bruising risk from manual handling. Corticosteroids affect bone density and tissue healing. A 2018 review in the British Journal of General Practice found that medication-exercise interactions were poorly understood by the majority of exercise professionals surveyed (Din et al., BJGP, 2018). Your trainer does not need to be a pharmacist. But they should ask about your medications and know when to consult your GP.
Communication with other practitioners. This is the single most important factor. A 2015 Cochrane review found that multidisciplinary rehabilitation produced 20 to 30 percent better outcomes than single-practitioner care for chronic musculoskeletal conditions (Kamper et al., Cochrane Database, 2015). A trainer who talks to your physiotherapist, reads their assessment notes, and adjusts your programme accordingly is operating at a fundamentally different level.
Questions to ask before you hire
These are direct questions that will tell you within five minutes whether a trainer is right for your body.
"What percentage of your clients are over 55?" If the answer is fewer than 20 percent, they may lack the pattern recognition that comes from working with older bodies daily.
"How do you modify exercises for someone with osteoarthritis?" A good answer involves specific modifications: reducing range of motion, avoiding impact loading on affected joints, using isometric holds, and progressing cautiously. A poor answer is vague or suggests avoiding the movement entirely.
"Do you communicate with your clients' physiotherapists or GPs?" If the answer is no, you will be the one carrying information between practitioners. That is where mistakes happen.
"What does your assessment process look like?" A qualified trainer assesses your movement before writing a programme. They check range of motion, balance, strength baselines, and ask about pain. If they hand you a generic programme on day one, that is a warning sign.
"How often does my programme change?" The body adapts to a stimulus within 4 to 8 weeks. A programme that has not changed in three months is no longer producing adaptation. A 2009 Cochrane review confirmed that progressive overload, meaning gradually increasing the challenge, is the mechanism behind strength and function improvements in older adults (Liu and Latham, Cochrane Database, 2009).
The team approach
The harder truth is that for most adults over 55 with any health complexity, one trainer is not enough. Not because the trainer is insufficient, but because the problems are multi-factorial.
A stiff shoulder might be a rotator cuff issue (physio), a thoracic mobility restriction (Pilates), a stress-driven tension pattern (psychotherapy), and a training load problem (strength coach) all at once. One person cannot address all of those.
A 2020 systematic review in The Lancet found that best-practice care for musculoskeletal pain involves coordinated physical and psychological interventions, not isolated treatment (Lin et al., The Lancet, 2020).
How Sway handles this
Sway exists because we believe you should not have to find and coordinate a team yourself.
Your Lead Coach assesses you first. Based on that assessment, they recommend the right specialists. Your strength coach, physiotherapist, Pilates teacher, nutritionist, massage therapist, and psychotherapist all share one clinical profile. They communicate weekly. Your programme adjusts as a unit.
Our strength coach Daniel explains: "My job is easier when I work with Sway than when I worked alone. I know exactly what my client's physio found. I know their nutritional status. I know if they are going through a stressful period. That context makes every session more effective."
What you can do today
If you are looking for a trainer, use the questions above. Write them down. Ask them in your trial session. The answers will tell you whether this person is qualified for your body.
If you already have a trainer, ask them one question today: "When was the last time you spoke to my physiotherapist?" If they have never spoken to your physio, or you do not have a physio, that is the gap where problems develop.
