Our Reviews

It’s hard to put into words how CFGY has enriched my life in so many ways. When I first started all I knew was I was READY to be a better version of myself. I wanted to be physically fitter, healthier and mentally more resistant. What I didn’t bag on was the sense of belonging and community that radiates from the place and the difference across peoples abilities. It’s not all about being hardcore! It’s about being the best possible version of you and doing your best. My class has an age range from peoples in their 20’s way up to 50’s it’s so diverse! I get so excited to see the WOD pop up for the next day and I can’t wait to get up and get stuck in. The motto is ‘people first, fitness follows’ it definitely shows here. I’d encourage anyone to come along and give it a shot. It’s changed my life. I love it and want to do it forever!! 🏋🏻‍♀️💪🏻🙌🏻

I joined Crossfit 2 years ago. It was the best move I could have made, I love the variety of the workouts so you can’t get bored or in a rut, the help and encouragement whilst training is second to none – I am fitter and stronger now than I’ve ever been and love to constantly push and challenge myself – doing things that I would never have thought I was capable of!
I would recommend Crossfit to anyone of any age or ability- the coaches are very knowledgeable and show great flair in scaling the classes so anyone can join in!
It’s not just the fitness, it’s the amazing Crossfit family and social life which comes with it- they’re such a great bunch of people! Go on – do it! Give it a go!
