Obesity Coaching Standard™
The standard that equips your gym to lead in obesity care and preventive healthcare.
The Clients Who Need You Most Walk Away
1 in 3 gym members cancels every year. Half quit within six months.
And the people leaving first are disproportionately the ones who most needed the gym — the overweight, the hormonally complex, the metabolically at-risk.
The ones who tried, didn't feel like they belong, and left.
This is not a pricing problem. It is not solved by better equipment, AI or cheaper memberships.
It is a competence problem, a language problem, and a business framework problem — all at once.
The fitness industry wants to become the frontline of preventive healthcare. But you cannot become the frontline of preventive healthcare while only retaining the people who were already healthy when they walked in.
The Untapped Business Opportunity
Only 1 in 6 UK adults holds a gym membership — yet 76% say getting healthy is their goal.
In the US, 1 in 4 adults is a gym member, leaving 75% of the population unreached.
The clients who most need preventive healthcare exist in enormous numbers. They just haven't found a gym that speaks their language or provides what they need yet.
A 10-location gym chain with 10,000 members that improves retention by 20%, attracts 2% new clients through refined marketing, and moves 5% of members to a health subscription generates £644,400 in additional annual revenue.
Year two ROI: 611%.
The gym that figures out how to offer coherent, structured support to these clients — rather than a scattered collection of upsells — will not have a retention problem.
It will have a waiting list.
Gyms that invest in staff training see 15% higher retention. Members working with a truly competent personal trainer stay at rates of 60-85%.
The difference is competence — combined with the language that speaks to the clients who need you most and a business framework built to serve them properly.
*Based on UK market data. US figures are comparable.
Figures are illustrative projections based on published industry data (HFA 2025, ukactive 2025). Results depend on full implementation of OCS certification, marketing framework, and health subscription pathway.
OCS™ - The Highest Standard Of Competence
The Obesity Coaching Standard is a rigorous 6-month, competency-based certification that trains your fitness professionals to support weight loss clients safely, ethically, and effectively — from the first session through long-term maintenance.
What makes OCS different is not the curriculum. It is the clinical depth.
Your certified professionals will understand not just the science of weight loss and metabolic health — but the minds, hormones, history, and shame of the clients who need support most. That understanding is the difference between a member who leaves after three months and one who stays for years — and sends their friends.
Enterprise Licensing — More Than Certification
OCS is not just a certification training - it's a complete system for serving the clients your gym has been losing.
OCS enterprise licensing gives your organisation everything needed to serve this client segment properly — not just trained staff.
Every enterprise licence includes
OCS certification for your team — your fitness professionals complete the full 6-month program and receive the Obesity Coaching Standard credential upon meeting the competency threshold.
Marketing language framework — ready-to-use language that speaks to the clients you are now equipped to serve. The overweight, the hormonally complex, the GLP-1 user, the 40+ woman who has never felt like the gym was for her.
Customer journey framework — a structured and detailed pathway from first contact to long-term health subscription membership. Your team knows exactly how to welcome, support, and retain these clients from day one.
Coming soon: Client-facing health guidance app — clinical-grade content on nutrition, sleep, recovery, hormonal health, and weight management, white-labelled for your gym. Currently in development - available to early enterprise clients.
Licensing is structured per location and scales with your organisation. Pricing is available on request.
Annual licence renewal and recertification are separate costs, tailored to your organisation.
Enterprise clients also have access to optional additional services:
Business consultations — strategic advisory sessions to help your organisation implement the OCS framework, build customer pathways, refine your service model, and maximise results.
Staff training days — on-site or remote training sessions for your wider team, beyond the certified professionals.
