Grand Union CrossFit

I LOVE it here. I hadn't done crossfit before joining about 10 months ago and I can honestly say that I now love going to the gym and actually miss it when I'm on holiday! I'd never really tracked what I'd been doing at the gym before but the six week programmes and app make it so easy to see your progress. My strength and fitness has improved a ridiculous amount and I'm so much more confident and happy in my body than I was when I started. Rob and Jenna are so fantastic and have pushed me to do things I never would have attempted before. Everyone is super friendly and supportive and the small classes mean workouts can be adapted for all abilities, sizes, preggos, you name it, so it really is such an inclusive place. If you're not sure about joining, just join.

Joining Grand Union CrossFit has been the best fitness decision I have made in years!!Rob and Jenna have created a wonderful community with some of the best coaching I have ever experienced. The workouts are brilliant with great variety and so much support within a really friendly atmosphere.There’s never any judgement from anyone and I’ve made some lovely friends since I’ve joined.Add to this absolutely banging tunes to workout to.Sign up, you will not regret it!!

Crossfit isn’t a gym it is a community and Grand Union is an exceptional example of this. I started here 3 years ago after 2 years of crossfit experience. The smaller size of classes means you learn a lot from the coaches and really improve on technique. The programming is challenging but fun and achievable.The best thing is there is very little ego at GU, everyone is really lovely, friendly and encouraging as can be seen at the various competitions members sign up for. I would recommend anyone looking to improve their fitness levels to come try it, a decision you won’t regret.

I have been going to Grand Union regularly since it first opened and how happy I am that it did! I had never done CrossFit before and was incredibly nervous but Rob and Jenna made me feel so at ease. They have created such a safe and supportive environment that I have never found before. They are much more than coaches and they make each and every person feel welcome.No matter if you’re a complete beginner or a CrossFit pro, they will always help with what is right for you and give you that extra push.I have moved away from Berkhamsted now sadly but I go back most weekends just to get a class in with them because I love it so much. What a place!!

I could write books about how amazing Grand Union is! After years of enjoying fitness but not finding my place I really feel I belong at GU. Everyone is incredibly supportive and friendly and it really does feel like a family! Rob and Jenna are absolutely amazing, inspirational coaches, they really care about everyones individual journeys and make hard work feel exciting! Their great programming means anyone and everyone can join and feel they have achieved something in every class! Going to GU is my favourite part of the day, it not only makes me physically stronger but mentally stronger in day to day life! I could go on and on but if you are thinking of joining I couldn't recommend it enough!!!!!!!

This place is so much more than a gym, theres a genuine community spirit and everyone is welcoming regardless of your ability - staff and members alike. The programming and coaching (and music!) is fantastic, every cycle pushes you in new ways and Rob and Jenna are constantly switching things up to keep it interesting. There is a big focus on scaling to suit your ability, but pushing for constant progression.I started coming here back in 2019 when it first opened, to complement my cycling training. Since then, Rob and Jenna have supported me through some big life changes, helping me to navigate pregnancy workouts safely, return to exercise post-pregnancy and giving me the opportunity to continue to train and progress in the most supportive, fun and welcoming environment as a mum to two little imps. It means so much to me to be able to train at Grand Union, and I get a real buzz out of mastering new moves and making progress.Thank for the incredible energy you put in to this place, Rob & Jenna. Martha and Iris can’t wait to start working out, too!

I have been going to Grand Union CrossFit for about a year now and it is the best gym, it is my favourite place to go to set me up for the day or unwind after work, I always leave feeling really positive. Rob and Jenna are brilliant coaches, I learn and improve something every time I go. Their programming is fun, varied and challenging and they also encourage everyone to do their best.Not only are they incredibility knowledgeable, they have created such a friendly community, and I’m so glad I am part of it. When I first joined everyone made me feel really welcome and that is testament to the environment they have created.They also really care and go the extra mile for every individual; I recently had an injury and they adapted every work out for me for about 3 months so I could keep on training. SIGN UP! You will not regret it.

I have never seen such an improvement in my fitness after joining a gym... My cardio health and recovery rate improved markedly within a month or so and I felt empowered enough to take on my first Hyrox at the ripe old age of 48. Rob and Jenna as coaches are the right mix of incredibly supportive, knowledgeable and motivational - and they really have the skills to back everything up! The community they have built at the gym is really something - no showboating here - just positive people working to make a difference to their health, mental and physical. What a team!
