The person best placed to supervise your exercise is someone trained in exercise for people with cancer, working alongside your care team. NICE guidance calls for supervised exercise on hormone therapy, but it names no single job title. A physiotherapist or a personal trainer may each hold part of the picture; cancer-specific competence is what matters most.
What does NICE say about supervised exercise for men with prostate cancer?
NICE recommends that men who are starting or having hormone therapy are offered supervised exercise, but it does not name a single profession to provide it. The guideline asks for supervision, not for one particular job title.
“Offer people who are starting or having androgen deprivation therapy supervised resistance and aerobic exercise at least twice a week for 12 weeks to reduce fatigue and improve quality of life.”
Read that sentence again and notice what it does not do. It does not say a physiotherapist. It does not say a personal trainer. Androgen deprivation therapy, or ADT, is the fuller name for hormone therapy. The word the guideline leans on is “supervised”.
Supervised means someone qualified sets your starting load, watches your technique, and adjusts the exercise as you go, rather than leaving you to work it out alone. The two named ingredients are resistance exercise, which is working your muscles against a weight or a band, and aerobic exercise, which is the kind of physical activity that raises your heart rate, such as brisk walking or cycling.
The benefits are stated carefully, and it helps to keep them that way. Supervised resistance and aerobic exercise has been shown to reduce fatigue and improve quality of life in men on hormone therapy (NICE NG131). It is not described as a cancer treatment, and neither is it here. Our companion piece, what NICE recommends for exercise on hormone therapy, unpacks the recommendation line by line.
So the guideline leaves you with a real question. If NICE asks for supervised, cancer-appropriate exercise but names no profession, how do you decide who is qualified to provide it?
What does a personal trainer usually cover, and where are the limits?
A personal trainer is qualified to guide general fitness for healthy adults. In the UK, a Level 3 qualification is the minimum needed to register as a personal trainer. A general qualification does not, by itself, include cancer-specific competence.
Personal-training qualifications in the UK are quality-regulated by Ofqual and recognised by CIMSPA, the professional body for the sport and physical activity sector. That Level 3 standard prepares a trainer to work safely with the general adult population, which is a genuine and useful skill set.
CIMSPA also sets separate professional standards for what it calls population specialisms, such as working with people who have long-term health conditions. These sit as additional standards, over and above the base personal-trainer role. In plain terms, working with a clinical group is treated as a further area of competence, not something the base qualification assumes.
Research in the UK makes the same point. A 2021 study of how to build exercise into the prostate cancer care pathway, the STAMINA trial by Reale and colleagues, found that standard exercise-professional qualifications do not address the core competencies of working with clinical populations, and that community-based exercise professionals need further, appropriate training to support men safely.
None of this is a mark against personal trainers, and a good one can be a real asset. It simply means the title on its own does not tell you whether someone has trained specifically in exercise for men with prostate cancer on hormone therapy. That is the thing to ask about, and we come to how in a moment.
What does a physiotherapist do?
Physiotherapy is a regulated profession that helps people recover movement and manage pain after injury, illness or disability. The NHS describes it as a treatment that can ease pain and improve movement.
According to the NHS, physiotherapy can help with problems affecting the bones, joints and muscles, as well as the heart and circulation, and breathing. It is a broad field, and much of it centres on rehabilitation after an injury, an operation or an illness.
It is also a regulated profession, which is a genuine reassurance. The NHS advises that when you choose a private physiotherapist, you check that they are registered with the Health and Care Professions Council, the HCPC.
Regulation tells you that someone has met the standards of their profession. It does not, on its own, tell you that they have trained in exercise for people with cancer. That is a separate area of competence, and the evidence shows it is not automatically covered. A 2024 Delphi consensus study by Kennedy and colleagues agreed on more than 100 core competencies, 103 in total across 10 areas, needed to deliver exercise to adults during active cancer treatment. It found that current training for both physical therapists and exercise physiologists includes some of these competencies, but neither covers all of them.
The point is not a criticism of any profession. It is simply that no single standard qualification, on either the fitness side or the clinical side, covers the whole of what cancer-specific exercise asks for. Which leads to the question underneath all of this.
So who is qualified to supervise exercise for men with prostate cancer?
The right person is someone with cancer-specific exercise competence, working with your care team. That is a level of specialisation rather than a single job title, and it can be reached by more than one route.
The international guidance points the same way. In 2019, an expert roundtable convened by the American College of Sports Medicine, led by Campbell and colleagues, published its Exercise Guidelines for Cancer Survivors and concluded that exercise training and testing are generally safe for people who have had cancer. The same guidance is written as a guide for the fitness and the health care professional working with cancer survivors, which tells you that supervision is a shared space, open to more than one kind of professional, provided the training is right.
So the answer is not a winner in a contest between job titles. A physiotherapist with cancer-exercise training, a clinical exercise physiologist, or a personal trainer who has gone on to specialise in exercise for people with cancer could each be well placed. What they would have in common is training in exercise for people with cancer, and a habit of working alongside your oncologist or consultant.
One honest limit belongs here. Exercise rehabilitation supports side-effect management; it is not a cancer treatment. Whoever supervises your exercise, they are helping you work on strength, fitness and everyday function while your oncology team looks after the cancer itself.
What types of physical activity does supervised exercise involve?
Two kinds, and a supervised programme usually blends them. NICE names resistance exercise and aerobic exercise, and both are ordinary forms of physical activity rather than anything exotic.
Resistance exercise works the major muscle groups against a weight, a band or your own body weight, and it is the part of the plan that works on muscle strength. Aerobic exercise is the kind that raises your heart rate, such as brisk walking or cycling. Between them they cover the two building blocks the guideline asks for, done at least twice a week over 12 weeks (NICE NG131).
Staying physically active in a structured, supervised way is the point. A specialist sets where you start on each type, keeps an eye on your technique, and builds the load gradually as the weeks go on. That is what separates a cancer-appropriate exercise programme from general activity you might do on your own, and it is why the guideline asks for the exercise to be supervised in the first place.
Why does cancer-specific training matter more than the job title?
Because prostate cancer and hormone therapy change what safe exercise looks like, and the standard qualifications for both fitness and clinical professions do not, by default, cover all of the cancer-specific skills involved.
Two findings sit behind this. The STAMINA trial found that standard exercise-professional qualifications do not cover the competencies needed for clinical populations (Reale and colleagues, 2021). The Kennedy Delphi study found that even the training of physical therapists and exercise physiologists, both regulated routes, includes some but not all of the 103 core competencies for cancer exercise (Kennedy and colleagues, 2024). Put together, they say the same thing: the job title alone does not guarantee competence.
This matters in practice because hormone therapy shifts the ground. It tends to reduce muscle and raise fatigue, so a plan that would suit a healthy adult may need to start lighter and build more gradually. Someone trained in this work knows to expect that, to set the starting load accordingly, and to adjust as your treatment goes on.
So the more useful question is not “physiotherapist or personal trainer?”. It is “does this person have training in exercise for people with cancer, and will they work with my care team?”. That is what turns general fitness knowledge into safe, cancer-appropriate supervision.
What should you ask before choosing someone to supervise your exercise?
Ask about three things: their training in exercise for people with cancer, whether the sessions will be supervised as NICE advises, and whether they will work with your care team. The answers matter more than the job title on the card.
A few plain questions will tell you most of what you need to know:
- What training do you have in exercise for people with cancer, and for men on hormone therapy in particular?
- Will the sessions be supervised, with someone setting my starting load and watching my technique? (NICE NG131 asks for supervised exercise.)
- Will you speak with my oncologist or consultant, and build the plan around my treatment?
- How will you decide where I start, and how will you progress the exercise over the weeks?
- Do you work one to one, so the plan is genuinely built around me?
If you are being referred by a GP, oncologist or family member, our guide on how to refer a man for supervised exercise sets out what to look for, and the information for clinicians page covers the same ground for a care team.
The honest bottom line is simple. NICE asks for supervised, cancer-appropriate exercise, and the person who provides it should be trained for exactly that, whatever route they took to get there.
How one-to-one specialist exercise rehabilitation can help
Once you know that cancer-specific competence matters more than the job title, the practical question is who can put that into practice for you. Specialist exercise rehabilitation is where that shape becomes real sessions built around you.
Piotr Kardas is a Prostate Cancer Exercise Specialist, Registered Clinical Exercise Physiologist. He works one to one with men who have prostate cancer, and with survivors. Each programme is built around supervised resistance and aerobic exercise, with the load adjusted as you go. Within that plan, Piotr integrates progressive resistance training with methods such as Tai Chi, Qigong, and Clinical Pilates. These sit inside the programme, chosen and adjusted for you, never as standalone products.
Piotr delivers specialist exercise rehabilitation for men with prostate cancer, at a world-leading NHS cancer centre, as a clinical exercise physiologist. Sessions run one of two ways: online by video call anywhere in the UK, or as a home visit in London or Surrey, arranged with Piotr and priced for your circumstances. Many men find a programme like this hard to arrange alone, and a specialist is one way to build it around you.
If you’d like to talk it through, you can book a paid 15-minute online video consultation with Piotr. It’s a calm, private space to ask your questions.
