Prime Performance Training

Training with Callum at Prime Performance Training has been excellent. His knowledge, professionalism, and personalised approach have helped me make significant progress in both strength and overall fitness. Alongside his expertise, his kindness and encouragement make every session enjoyable and motivating. He has also been incredibly helpful with my hypermobile shoulder, adapting exercises to improve stability and help me train with confidence. Georgia Peel 😊

I've only been with prime 3 months now, and the progress I've noticed is insane. I used to have a PT before and go to the gym, but was hit and miss. Since I've joined i finally got to love every single workout I do. I started going 5 days a week because I dont want to miss a workout. The combination of strenght training and HIIT sessions, have allowed me out of nowhere to go out running with no pain and high resistance. Love the place, nice and clean, toilets with a little station with deodorants, sanitary pads, hair bands, is all in the little things. And the best part, the coach, Cal is so approachable, knowledgeable and easy going, pushes you without pushing you 😄, and he created an amazing community where everyone supports each other, and the only way you get competitive is with yourself. 100% recommended.

It’s rare to find a training facility that truly has it all: great coaching, up-to-date equipment and a welcoming community. Prime does exactly that with its SGPT sessions, which have been instrumental in helping me build both strength and confidence in the gym. Perhaps most importantly, Cal is genuinely invested in his members and wants to see them achieve their goals. It’s this kind of mentorship that’s hard to replicate in bigger, commercial spaces. I’d highly recommend Prime to anyone looking to level up their strength and fitness in a supportive environment.

Late last year, I secured a place in my first HYROX event and wanted to find a gym that offered dedicated classes to ensure I was training with the correct techniques ahead of 2026. In January, after a recommendation from a family friend (and spending some time researching gyms on Instagram), I reached out to Cal about joining his Saturday HYROX class. From my very first session, I felt genuinely welcomed—everyone was introduced, and the environment immediately put me at ease. Training with Cal twice a week has had a huge impact. I achieved my goal of a sub-2-hour HYROX time in March and have also recently set a new personal best in my half marathon. Cal is incredibly accommodating, and the gym he has created is both supportive and motivating. I would highly recommend him to anyone interested in HYROX training or simply looking for a great new gym with great people!

Prime is the first gym in Stortford where I genuinely look forward to every session. I used to avoid weight training, but now I absolutely love it. Six months in, I’ve hit goals and personal bests I never imagined possible. That’s not just because of the quality of the programming, but also the self-belief Cal instils in everyone he works with. He’s constantly helping me achieve more than I thought I was capable of. Prime has been an absolute game changer for me. The community is so welcoming, and there’s always a laugh during training. I can’t recommend it enough!
