Fantastic experience: I am deaf my first language is British Sign Language. I thought this was going to be a big challenge for me to go to CrossFit classes as the coaches didn’t know BSL. It was my best decision that I joined Crossfit Kelham. It’s been 3 years now. All coaches are very knowledgeable, friendly and welcoming. CrossFit is definitely more fun than normal gym.

Fantastic experience: Easily the best hour of my day. I was apprehensive about joining CrossFit but the team were so welcoming and supportive - I’m so glad I did. The classes are well structured and lead by knowledgeable coaches. The programming is also very engaging and can be easily adapted to suit everyone. The gym attracts a great crowd and it’s always just great to be there. Since moving away from Sheffield I no longer train here but will always look for an excuse to drop in!
Thank you Ling, you’ve come for far in your CrossFit journey! Well done

Every coach is enthusiastic, knowledgeable and friendly. It’s a fantastic group of coaches and members, if you’re lucky enough that a space comes to join you won’t regret it!
Fantastic experience: I spent about 8 months as a member at CFK whilst working out of town. The place is a addictive. CrossFit is addictive. All you need to do is keep turning up and you will become fitter and stronger and if you want to become a athlete the coaches and setup is there for you to achieve this goal. I’m gutted to be leaving Sheffield and CFK behind.
Thanks a lot Chris! Sad to see you go, good luck with the future!
Fantastic experience: I have been away from CrossFit for about 4 years and was a bit nervous about returning. Everyone was very welcoming and the programming is very good. The class times work well for me in the mornings and the fact you have to book on means they are never too busy.
Thanks David! Great to have you as a member
Fantastic experience: Dropped in twice this week and have to say such a friendly bunch of people… dropping in is always a bit scary! Great facilities… great programming… great people! Will be dropping in again!
Fantastic experience: Really cool place nice staff. I had to cut my membership short due to injury and work but will be looking to return.
Fantastic experience: CFK has been a highlight of my last year working in Sheffield. The gym itself is well equipped, the classes are fun, varied and adaptable to any fitness level, but the best thing about this place is the people. The coaching staff and members alike are all so friendly and welcoming from day one, as well as being extremely knowledgeable and helpful. It has a truly unique community atmosphere that sets it completely apart from most commercial gyms I've been to. I will miss this place and the people a lot! For anyone who is into, or wants to get into pursuing fitness, I cannot recommend it enough.
Thanks so much Ethan! You’ve been an awesome member
Fantastic experience: Really great gym. When I started CrossFit last May I was a bit nervous but James, Rebecca and all the other coaches are brilliant and I very quickly grew to love it. If you're thinking about joining a gym definitely give CrossFit Kelham a go.
Thank you so much Sally!
Fantastic experience: CrossFit Kelham has been a game changer for me. Having used commercial gyms and group fitness classes for years, this just doesn’t compare. James, Rebecca and the rest of the team are encouraging, supportive and knowledgeable. The format of classes means you are always learning and making progress, leaving with a sense of achievement each time. They’ve created a community atmosphere in CrossFit Kelham that I’ve never experienced. It’s not just a workout, it’s something you make time in your day for & something to put a smile on your face (through the tears of sweat). If anyone is fed up of the normal gym environment, give CFK a try. Special shout-out to James for being up with us at 6am on Zoom in Lockdown- providing the mental boost we needed.
Fantastic experience: Loving it at CrossFit Kelham! Varied, challenging workouts (adaptable to all abilities). The staff and community are really supportive and friendly. Well worth getting up early in the morning for!
Fantastic experience: Great crossfit gym, very spacious, fully equipped, fantastic and caring trainers. Could not ask for anything else. Thank you James and Rebecca for everything you do, the care that you show everyone and the sense of community that you've instilled in everyone
Fantastic experience: Crossfit Kelham is a family.. I'm due to change job soon and one thing I was worried about was finding a group of people I can socialise with a have a good time and keep physically and mentally fit... Over the past couple months I can already feel my fitness and motivation has changed positively... All the coaches and members are class and encouraging and from day 1, If you're not a member and trying to better yourself then you need to get yourself here.
Thank you so much for your lovely words Matt, we’re lucky to have you as a member! Keep crushing it
Fantastic experience: Great place for workout and great coaches! community atmosphere.
Fantastic experience: Good location, friendly and professional staff. Recommend to check this place up
Fantastic experience: Used cheap gyms for years and always hated having to think up my own workout plans and struggling to get on the equipment I wanted to use. CrossFit has solved both of those problems for me as the coaching team do a great job ensuring sessions are always varied and fun, plus fixed class sizes means there’s no fighting to get the bits of kit you need! All the coaches are great and really helpful and doing the same workout as the rest of the class is great motivation.
Fantastic experience: Welcoming and friendly gym teaching every single aspect of CrossFit. Being new to CrossFit I’ve found the CrossFit classes which are near enough 1 on 1 teaching sessions very helpful and motivating. This place is ideal for people with any level of fitness, from young to older. Great place to learn new skills, James and Rebecca are excellent coaches!
Fantastic experience: I joined CrossFit S2 having never attempted CrossFit before, but with the amazing coaches James & Rebecca and relatively small class sizes it was easy to learn the skills and progress quickly. If you're thinking of joining I highly recommend you get in touch and just give it a go!
Thanks a lot Charlie! Hope Germany’s treating you well
