Sea City CrossFit®: Opinions
Fantastic experience: Sea City is easily the best thing I have done in my many attempts to get fit and stronger. I was nervous before my first session as this was something completely new, and I've never been confident in gyms or classes. But I really didn't need to be. The atmosphere is excellent, both from the coaches and other members; in one of my first sessions, other members were encouraging me when I was really struggling and ready to give up or take it easy. Emma and Dan have created a really welcoming, supportive, and fun environment. I also feel I am pushed every session by Emma and Dan, along with Emily and Joe, the other two excellent coaches, to levels I would never get to in a gym, while also having workouts tailored to my current ability, strength, mobility and flexibility so that they remain safe and my form/technique is steadily improving every session. Smaller classes mean I always get the support and advice I need. Sea City is excellent; I look forward to going to every session, and I would highly recommend it.
It's a pleasure to have you in class Matt! Thank you for your kind words. You're doing awesome.
Fantastic experience: I joined Seacity in April, having never done Crossfit before. Tbh, I wasn't sure at first, smaller groups, programmes and work outs I've never done or tried before. But I can honestly say, after 5 months, of being part of the Seacity family, and that's what it is, I would recommend. It pushes me to do things / try things I'd never do in the gym. It keeps me consistent, ive seen progress in my ability, and the people are super supportive and friendly and there is a lovely social feel to the club.
Fantastic experience: Whether your into your CrossFit or not, you need to give this place a go. Very welcoming atmosphere and top notch equipment. Was feeling a bit unmotivated to train but that soon changed when I walked in. Great set-up and would deffo recommend.
Fantastic experience: Come join the community. Great x fit gym. Full of friendly helpful people. The coaches, know their onions

Fantastic experience: Emma and Dan are great coaches and owners. Well run, friendly and supportive CrossFit box. Very welcoming and inclusive community!
Cheers Buffy!
Fantastic experience: Due to the small nature of the classes the support given is much higher than in other boxes. Its almost has having a personal trainer making sure your technic and performance are correct. Doesn’t matter your fitness level they will scale it on order for you to progress during your training.
Thanks Joana!
Fantastic experience: With a great team atmosphere, knowledgeable instructors that really take the time to set you up to succeed and a wide variety of activities throughout the classes you'll actually look forward to going to the gym!
Thank you Max!
Fantastic experience: I really needed an alternative to the usual gym that motivates, teaches and pushes you all the way and the guys at Sea City CrossFit really provide this in droves. It’s a great atmosphere and really friendly. No egos and everyone is really welcoming and helpful. Thanks guys and keep up the good work
Appreciate it Chris!

Thanks Darryl!
Fantastic experience: As someone who had never done crossfit or any weightlifting before, I have really enjoyed the sessions at Sea City CrossFit. The instructors help me to scale the exercises to things I can build on, and everyone is welcoming and enthusiastic!
Pleasure having you with us Jenny!
Fantastic experience: I have been a member of Sea City since September and I honestly LOVE it and enjoy it so much! Dan and Emma are very professional and motivational, and everyone is so friendly and welcoming! One of the best decisions I made in 2021 :)
Thank you Celia!
Fantastic experience: Joint in 2021. Enjoying it ever since. Venue is small, equipment is good. Because of the small venue you get almost 1on1 coaching. Emma and Dan are fab. Very knowledgeable and excellent coaching. All abilities are welcome and receive excellent coaching. I’m pleased with the progress I have made so far and I’m confident I keep progressing.
Thank you Simon! Pleasure to have you with us
Fantastic experience: I've been training here for 2 years or so. I can honestly say this is the best gym I've ever trained at. The coaches are AMAZING, the programming is spot on and the members are legends. Every area of my fitness has improved beyond what I thought I was physically capable of. I’m never leaving! #seacity4lyfe
Fantastic experience: I came to Sea City to try and improve my strength to help with a longstanding injury. I'd been in pain for more than a year when I started. I'm now 5 months into membership and virtually pain free - the coaching by Dan, Emma and Gabs is second to none, class sizes are small and everyone is incredibly friendly and encouraging, even if you're a seized up internet addict like me. 100% wld recommend. - Tosh
Thanks Tosh! Pleasure having you with us.
Fantastic experience: Thoroughly enjoyable box to train at. Great coaches really nice people very varied workouts. Much smaller classes than at other CrossFit gyms. Perfect whether it’s your first ever crossfit class or if you have been doing it a while this gym is perfect for you.
Thanks Chris!
Fantastic experience: This is my first time going to a CrossFit gym and SeaCity have been simply incredible. Dan and Emma are so friendly and break everything down so it's not intimidating. Also everyone in the classes is so lovely and supportive - so grateful for this community!
Appreciate it Naomi!
Fantastic experience: Having been put off other CrossFit boxes due to it being a bit too much like a cult, its been great to discover the Sea City crew. Dan, Emma and Gaby are enthusiastic, knowledgeable and encouraging without crossing over into that slightly weird place where I'm told I have to eat coleslaw for breakfast. Absolutely recommend giving it a go!
Coleslaw for breakfast happy to have you with us Rich!
Fantastic experience: I am new to Brighton and wasn't sure what CrossFit box to join, but Sea City came highly recommended and I see why! The community is tight, everyone is friendly and welcoming. The programming is made so you get the best workout tailored to your fitness level which makes everyone feel like they had a great workout. I really appreciate how the coaches keep me honest while keeping things fun!
Thank you Sarah, we’re happy to have you with us!
Fantastic experience: Best decision I made in my fitness journey. My aim was to become stronger, improve my endurance and stamina. One important aspect to me is always: " but how good is the teaching" . Sea city crossfit has the best coaches. Emma and Dan are extremely knowledgeable, experienced and really care about your success. And that in return gives you the confidence to push further. The atmosphere is incredible and there has not been a day were I left thinking " thank f*$%# that was good "
Thanks Steph, you're smashing it!
Fantastic experience: Awesome CrossFit box!! Coaches are professional whilst also being super friendly and approachable. I have been to 3 different CrossFit boxes and SeaCity is my favourite by far. It’s the perfect place if you want to really push yourself to reach your fitness goals or to start out on your fitness journey. They make an effort to make everyone feel welcome and I leave the sessions buzzing! Can’t recommend it enough!
Thank you Leasa!
Fantastic experience: I've been a member for over three months and can honestly say it's been the most rewarding and challenging type of fitness I've participated in. Initially I joined with a membership for 3 sessions per week. I soon upgraded to allow me access to all the classes Monday - Saturday. The programmes are well thought out and challenge all aspects of your fitness. What really appealed to me is the skill development and improvement of technique in many functional movements and lifting. I quickly realised that I have picked up many bad habits and form from working out in a gym. The coaches are brilliant. They will spend time with you working on improving form and technique. Especially when you are new to the class. It feels like you are learning something new each time, which helps with motivation and dedication. They are very approachable and super friendly. Making you feel part of the CrossFit community from the off. It is a great environment to train in as other club members are very supportive and encouraging. People are always smiling (even after a seriously hard session). I'd thoroughly recommend joining Sea City no matter your levels of fitness or ability.
We’re happy to have you with us Chris and really appreciate this review. Thanks!
Fantastic experience: When I started, I was super scared of joining a CrossFit gym. So many myths and legends about crazy crossfiters who just care of lifting billions of kilos and speak about the best timing in the workout. Not at all. Here I found a very welcoming place, full of amazing and kind people that always smile and always help you. You don't have to be fit, muscled, big to do CrossFit. You don't need to have a past of weightlifting or gym going. You just have to be willing to learn and have fun. And all of this is possible thanks to the best coaches ever. Super qualified, super patient, super respectful, and super friendly!!!!
Thank you Giada!
Fantastic experience: Great atmosphere, great coaches and members...
Thanks Joana!

Thank you!
Fantastic experience: I've been a member for almost two months and I'm already making so many progresses! The coaches are great, very nice and competent and the environment is very friendly and supportive. Definitely recommend it!
We're happy to have you Flavia!
Fantastic experience: Such a great place! The spaces are very limited and it feels almost like personal training. I would highly recommend it to anyone who would like to push their fitness to the next level.
Awesome, thanks Maria!
Fantastic experience: I've been a member of Sea City for around 18 months. It was only moving to this Box I realised how much focussed programming and attentive coaching can make such a difference to my progression. Gymnastics and Olympic Lifting has improved no end. That aside, its a great bunch of humans who work out, no cliques, dramas or egos. Actually is the best hour of my day. :-)
Thanks Vicki!
Fantastic experience: I joined Sea City CrossFit about a year ago and I'm totally appreciating the excellent coaching and feedback. I feel much more solid in my technique. It's a great community and everyone is made to feel really welcome.
We're so happy to hear it, thanks David!
Fantastic experience: I have attended other Box’s in Brighton and Hove and I can honestly say that this is the best one. The Trainers Emma and Dan are both friendly and supportive. They are able to break things down and explain new movements clearly. The box feels really inclusive and there is always a great atmosphere. I can’t recommend it more!
Thanks Stevie!
Fantastic experience: I've been doing crossfit for a few years but it wasn't until moving to SeaCity that I had this level of teaching and such an amazing variety of workouts. They make sure that your technique is on point and that every part of your body gets stronger and fitter. The box also has the most inviting and welcoming atmosphere of any I've been to. I love it.
Thank you Loulou!
Fantastic experience: I spent a year training at SeaCity CrossFit. Fantastic coaching, amazing community and guaranteed results. Regardless of whether you’re a beginner looking to establish fitness goals or an experienced athlete looking to get better, Sea City CrossFit is for everyone.
Abi! Thank you
Fantastic experience: So glad I joined Sea City CrossFit! Great community, excellent coaches and the best workouts. I noticed a difference in my strength and stamina after just 4 weeks. 3 months in an I'm still loving it and feeling stronger than ever. Highly recommended!
So glad to hear it, thanks Uta!
Fantastic experience: I have been with SeaCity for about a month and have really enjoyed it. I was nervous when first joining as I have not done anything like this before, but Emma and Dan were really welcoming and made it work to my fitness level. I have enjoyed every class I have done so far, not only is everyone so lovely, but also so supporting! I like how you get to do a bit of everything, I would definitely recommend!
Thank you Yas. Pleasure to have you in class with us!
Fantastic experience: Just had my first olympic weightlifting class at CrossFit Decennia! So chuffed with what i accomplished tonight and the club are so friendly and welcoming
Fantastic experience: Many thanks to Dave and Emma at Decennia for fitting me in for three sessions during my visit to Brighton last week. I appreciated your availability on short notice and excellent technical tuition. I am working on it. I will make a point to return when next in Brighton in late September. Francesca Ardigo
Fantastic experience: Coming back to Crossfit after having 2 babies and being totally unfit was scary. Emma, David and Damo have been a brilliant team. They have encouraged me and I have lost 1.5 stone in weight in the last 5 months and lots of inches. They have been so kind and scaled the exercises whilst making me feel so welcome. If you are thinking of starting/trying or are a high level athlete in CrossFit, Decennia is a fantastic place to train.
Fantastic experience: Five stars are not enough! Decennia is a deceptively small CrossFit box with huge benefits: limited class sizes means everybody gets the coach's attention, excellent tuition and motivation creates an amazing atmosphere in which to train and superb quality coaching ensures rapid results and gains. After five years away from CrossFit, Decennia had me hooked again within a week.
