People ask me sometimes what actually separates what I do from what happens at a gym. It’s a fair question. Both involve exercise. Both involve a person guiding you through it. But the qualification behind that guidance changes what’s actually happening in the room — and, for anyone managing risk on behalf of a workforce, it changes what you’re paying for.
The distinction is now formally recognized
This isn’t just a branding line. In the UK, clinical exercise physiology became a regulated healthcare profession in 2021, with the Academy for Healthcare Science establishing a formal scope of practice and an accredited master’s-level curriculum (Clinical Exercise Physiology UK progress report, 2024). A personal trainer works on general fitness with no clinical scope. A clinical exercise physiologist uses exercise as a treatment tool for people with diagnosed conditions, often under physician referral — reading movement history, running assessments, and building programs around actual risk factors, not just goals.
That gap shows up in the data, too. A 2022 UK study comparing staffing across five specialised clinical exercise services found that 88% of exercise-delivering staff in cancer services didn’t hold a relevant undergraduate degree or higher (Crozier et al., BMJ Open Sport & Exercise Medicine, 2022). A follow-up 2023 study looking specifically at how a UK cancer-specific clinical exercise service is structured found the same pattern in practice — the programs getting attention for doing it well were the ones staffed by degree-qualified specialists working to a registered clinical standard. It’s part of why exercise oncology, as a discipline, is starting to demand the same clinical rigor as physiotherapy.
Why this matters for something as serious as cancer
This is the part I spoke about at the Cancer Prevention Workshop at Hilton Resort Mauritius last October — an initiative of communicationsC!, delivered with support from Mauritius’s Ministry of Health and Wellness. The research behind exercise oncology has grown substantially in the past five years, and it’s worth being precise about what it actually shows.
A 2025 meta-analysis pooling data on breast, lung, prostate, colorectal, and skin cancer found that higher post-diagnosis physical activity was associated with meaningfully better survival outcomes — a 31% lower mortality risk in breast cancer patients and a 27% lower risk in prostate cancer patients, compared to those who were less active (GeroScience, 2025). This is observational, population-level data, not a claim that exercise treats or cures cancer — but the association is now consistent enough that organizations like the American Cancer Society and the American Society of Clinical Oncology have moved from expert opinion to formal exercise guidelines for cancer patients.
That’s the point I try to make on stage and in every session I run: movement isn’t a wellness add-on. In prevention and in recovery, it functions alongside medical care — never instead of it.
What this actually looks like day to day
None of this requires an intensity most people associate with training. It requires precision. A proper assessment before the first session. A program built around what your body can actually handle right now, not a generic template. Adjustments as circumstances change — injury, recovery, a stressful quarter, a diagnosis. That’s the difference between exercise as a category and exercise as a clinical tool.
It’s also the standard I hold every session to, corporate or individual — whether I’m working with an executive managing chronic pain or leading a workplace wellness talk for a hundred people who’ve never thought about it this way before.
