Stronger. Leaner. Healthier.

Redefine Your Prime — Fitness That Transforms Body, Mind & Life

Not just another gym. We’re Bicester’s home for transformation — designed for people over 35 who want lasting results, not quick fixes.

About

At 1st4Fitness, we don’t believe your best years are behind you.

We believe your prime is something you can redefine — at any age.

We specialise in helping men and women over 35 transform not just their bodies, but their confidence, energy, and outlook on life. For us, “fitness” isn’t about six-packs or living in the gym. It’s about giving you back the strength, mobility, and belief that you can do more, live better, and feel proud of the person looking back at you in the mirror.

Our approach is holistic:

More Than Just a Gym

Most gyms give you access. We give you transformation.

Our approach is holistic:

Personalised training plans designed for your body and goals
Nutrition coaching that works in real life (yes, you can still enjoy your favourite foods)
Mindset and accountability support so you never feel like you’re going it alone
A welcoming community that feels more family than fitness

We don’t throw you into a one-size-fits-all programme. Every detail — from your first 1-1 Game Plan Consultation to your progress check-ins — is tailored to you.

Our Mission

To redefine how people see health and fitness, so you can live a longer, stronger, healthier, and happier life.

Our Vision

To be one of the world’s leading body transformation specialists for people over 35 — proving that your prime isn’t behind you, it’s waiting to be redefined.

Our Values in Action

Accountability — We give you the tools and hold you accountable to your goals.
Adaptability — Every program flexes to fit your lifestyle, not the other way around.
Strength — Not just in muscles, but in resilience, confidence, and mindset.
Confidence — Helping you believe in yourself again.
Learning — Breaking myths, unlearning bad habits, and keeping things simple.

To be one of the world’s leading body transformation specialists for people over 35 — proving that your prime isn’t behind you, it’s waiting to be redefined.

Meet Your Coaches

Behind 1st4Fitness are coaches who live and breathe transformation. We’ve been in your shoes, tried the quick fixes, and know they don’t work. That’s why we built something different — a place where real people achieve real, lasting results.

Paul Clutterbuck – Co-Founder & Head Coach

I first qualified as a Personal Trainer back in 2004, but like many of our clients, life took me in another direction for a while. In 2014, I came back to the fitness industry with a clear mission: to help people cut through the noise of fad diets, quick fixes, and gym intimidation.

My focus isn’t on building athletes — it’s on helping everyday people over 35 move better, feel stronger, and transform their confidence. Over the years, I’ve seen clients go from struggling with knee pain or self-doubt to achieving things they once thought were impossible. Those moments are why I do this.

At 1st4Fitness, I bring together evidence-based training, sustainable nutrition coaching, and a healthy dose of accountability.

My style? Straightforward, supportive, with a bit of humour — because fitness should feel like progress, not punishment.

I’ve always believed that fitness is about far more than what you see in the mirror. For me, it’s about creating a stronger, healthier, happier version of yourself — inside and out. That belief is what drives my coaching at 1st4Fitness.

I specialise in working with clients who have struggled with consistency, confidence, or knowing where to start. Seeing someone go from “I hate exercise” to walking out of a session proud, energised, and even excited for the next one — that’s what lights me up.

I’m passionate about building a community where people feel supported, not judged. Fitness should be empowering, and with the right plan and encouragement, I believe anyone can redefine their prime.
