Grand Union CrossFit

I've been a member of this box for almost a year now. Myself and husband moved to the area and were looking for a good gym to join - we did a trial session with the coaches and loved it.

I had some previous CF experience but since coming to GU I have improved in every aspect - gymnastics, fitness and strength. Rob and Jen, the coaches, are really supportive and encouraging to every member - no matter your own fitness background. The programming from the coaches, in my opinion, is guaranteed to make you progress.

CrossFit gyms are generally more expensive and I used to grudge paying that for something that wasn't really worth it. But at GU you feel like you are always at a personal training session in every class. If there's an exercise that you don't feel comfortable with, the coaches are more than happy to give tips and tricks to get better at it.

Both Rob and Jen are a massive inspiration to me on a personal level from running their own businesses and they also happen to be very fit and strong too :)

For anyone that's thinking about trying it out - just do it, there's diffrent aspects to Crossfit that you will love more than others. But you couldn't pick a better gym to try it out than at GU!

Joining a couple of years ago was one of the best decisions I’ve made. I was always intimidated in conventional gyms and to be honest had absolutely no clue what I was doing! However with GU, it feels like a personal training session every time with small classes, one-to-one feedback and constantly varied cycles that have helped make me fitter and stronger than ever. Not to mention it has a great community aspect with friendly members and regular social events.

I never stuck to any sport in my life… until GU CrossFit…. Best coaches, who are kind, fun, push you. They created the most wonderful CrossFit community in Berkhamsted, exercising is fun and I have seen amazing results in my fitness.

I joined GU nearly 2 years and can honestly say best decision I ever made ! the change in me is noticeable to everyone , not just my physical changes ( but i have got very strong !!!! ) but the mental impact is something i never expected ! I am calmer, happier, sleep better and feel mentally stronger . I have set myself so many goals that I have gone on to smash and its feels great ! The difference with GU than other gyms is the people, Rob & Jenna are fantastic coaches and have created something unique , a family , a community where people support each other, root for each other ! I have made some dear friends here ...... as I said joining was the best thing I have ever done

If you're looking for buff units, look no further.

Just joking, GU is much more than a gym, it is a community. Most people who have joined in the last three years are now part of a wider social circle that is as well known for legendary parties, as it is for PBs and physical development (but there is a lot of that too).

Rob and Jenna lead from the front, and they are as pateint as they are demanding.

Jenna and Rob at GU are the best coaches. I’ve been doing CrossFit for a while now and I can safely say that the classes, equipment, facilities and most importantly, the people make it.

There’s no ego in the room, just really great programming and an inclusive culture.

I’ve met some awesome people at GU, and since joining I’ve hit a number of PB’s on my squat, clean, snatch and more.

Couldn’t recommend a better gym. Check it out 👊🏻💪🏻

I joined GU Crossfit in October 2019 after a friend recommended it and I have not looked back since. The owners and coaches are brilliant, extremely knowledgeable and patient when teaching new skills. I tended to stay away from gyms and weights especially, but they have given me the confidence to use a gym. The community as well within the gym is brilliant - couldn't recommend it more.

One of the most professional and dedicated gyms around. Rob and Jenna are such great people, you can really see the love that they have for the CrossFit community, as well as the local community in Berkhamsted and surrounding areas. Their hard work really shines through in everything they do, despite being closed over many months of lockdown they have persevered and driven their members to stay fit. They've done zoom classes and free to all sessions on many occasions. My experience is largely from the community work-out bingo (GUBingo) where I experienced Rob and Jenna's drive and motivation, it really challenges you to do the maximum you can. A massive thanks to them for the challenge!
