After completing his qualification, Callum Foster turned his ambition into a thriving career built around helping disabled people discover what they’re capable of. Along the way, his work has reached millions online, inspired other fitness professionals to specialise in inclusive coaching and earned recognition from some of the biggest names in sport and fitness.

But despite the growing audience, Callum’s focus has never changed. His priority remains the people in front of him, helping each individual build confidence, overcome barriers and achieve things they once believed were impossible.

In the final part of our learner spotlight series, Callum reflects on building an audience with purpose, his long-term ambitions and the advice he would give to aspiring personal trainers looking to make a meaningful impact.

In this article, you’ll learn:

• How Callum built an audience through authentic storytelling
• Why social media became a tool for advocacy rather than self-promotion
• His long-term vision for inclusive fitness
• Advice for personal trainers looking to specialise

Building an Audience Through Authenticity

The platform grew because the work was real, and for no other reason. In those early sessions it was never about building an audience. Families who had perhaps been told for years what their loved ones couldn’t do were watching them do it, and that energy, that genuine joy in a moment of someone realising their own capability, that is what people connected with when it started reaching further afield.

I want to be honest about how the growth actually happened because it was not a sudden breakthrough that changed everything overnight. There is a pressure on social media to find the viral remedy, to crack some formula that suddenly makes everything explode, and for a while I felt that pressure too.

I was exhausting myself trying to show up everywhere, every day, keeping every platform moving at once. Eventually I stepped back. I stopped trying to be constantly present and started being intentional instead. When I did show up, I made sure it was to the highest standard I could possibly give.

That shift changed everything.

What I have learned is that you probably already have everything you need. The content is already there in front of you, in the sessions, in the people, in the moments that move you. You just need to make it your own and trust it.

Quality Over Quantity

Big goals used to feel overwhelming to me and the scale of what I wanted to build was difficult to hold clearly when I tried to look at it all at once. What changed things was learning to focus on the short term, to build consistent habits and to commit fully to quality over quantity.

I did less, and when I showed up I gave everything to it, trying to capture something true about the people I was working with: the determination, the strength, the significance of a moment that the wider world might easily walk past without registering.

I deleted things and reposted them more times than I can count, not because the content was poor but because I cared deeply about doing the person in the frame proper justice.

It has never been about me, not once and not ever, and I think people feel that difference immediately. The sessions, the clients, the relationships built over months and years of showing up consistently, that is what the platform reflects.

Nearly 60,000 followers, videos that have amassed over five million views and messages of support and love that I genuinely never anticipated receiving. The younger version of me coaching in that garden cannot quite believe it, and honestly, I am not sure I want him to stop feeling that way. That sense of disbelief keeps it meaningful.

What I know with complete certainty is that what I am putting out into the world comes from a real place, built on real relationships with real people who deserve to be seen. That has always been the foundation and it always will be.

Staying Grounded

Seeing brands like Gymshark and athletes like Ilona Maher take notice and engage with the work is something I am genuinely grateful for, but it doesn’t change my life or how I move through it.

I stay grounded in what actually matters.

The beauty of this work has never been the posts themselves; it lives in what the content captures, in the real moments between real people.

Social media has given the business a platform it would never have found otherwise and leveraging that has allowed This Ability Coach to truly blossom, but it has always been the work that led the way.

The follows, the comments, the recognition from names I grew up admiring, I receive all of it with gratitude and then I get back to the session.

That is where the real work happens and that is where it will always happen.

Looking to the Future

The long-term vision is a physical space. A gym built from the ground up with these clients genuinely at the centre of every decision, not adapted as an afterthought or made accessible in only the minimum required sense, but a place where every one of these incredible individuals can truly call home.

Somewhere they can move entirely on their own terms, at their own pace and with the specific support they need rather than a standardised version of support that was designed for someone else. A place built in deliberate response to the limitations that have been handed to these people for far too long by a world that was never designed with them in mind.

The vision goes beyond exercise though.

I want to create a hub that genuinely changes lives in the fullest sense of that phrase, a space where employability support sits alongside physical coaching, where someone can walk in needing help with their fitness and leave with more confidence, more skills and more belief in what their future could look like.

The dream, and one I am actively working toward, is a place where exercise is free. Where cost is never the barrier that keeps someone from accessing something that could change everything for them.

I know that takes time and I know it takes resource, but I also know it is possible and I am not prepared to stop until it is real.

Baby steps, as I always remind myself, but the destination has never been clearer.

Why The Work Continues

Despite growing awareness of inclusive fitness, significant barriers remain.

• Fewer than 1% of UK gyms are accredited through the Inclusive Fitness Initiative. (Disability Rights UK)

• 25% of the UK population have a disability, representing millions of people who should have equal opportunities to experience the benefits of movement. (Commons Library).
• Nearly seven in ten disabled people who experience loneliness said being active could help them feel less lonely.  (Activity Alliance).

Advice for the Next Generation of Coaches

To any PT reading this who is thinking about specialising in inclusive fitness, my advice is simple.

Start with belief. Belief in your own ability to change lives, because you have to genuinely believe in yourself before you can truly believe in anyone else.

Practice what you preach, show up with real intention and do everything with the specific purpose of making a difference to the person in front of you.

Pursue real education, the kind built around equity rather than equality, that gives you space to develop your own approach rather than handing you a method designed for someone else entirely.

You don’t have to have it all figured out. I still don’t, and I say that honestly. What I do know is that my intentions are right and that clarity of purpose matters more than having every answer.

My clients believe in me because I believe in them, unconditionally and without reservation, in exactly the way my grandad believed in the people around him and in me.

You leave a mark on the world through your presence, through the way you communicate and through the love you bring to the work. Not through a revenue figure, a follower count or a level of qualification.

Lead with positive impact, hold that as your compass in every session and every decision, and the rest will fall into place around it.

Even though my grandad won’t get to see what I have built, I know he would be proud of me, and that is my purpose.
