D12 CrossFit®: Opinions
Fantastic experience: Have used many crossfit gyms over the years in the USA and was recently in town (Dublin) for a month and came here a number of times. Very impressed. Great gym, extensive equipment, well organized; very nice and welcoming owner, Alan.
Fantastic experience: I did two drop-ins 3 months ago and the coach and the people made me feel at home. Great premises and equipment. Thanks to Coach Alan for his pointers!
Hey Antonio, Thanks for the review. It was great to have you in on your visit to Dublin.
Fantastic experience: Passing through Dublin for 3 months, D12 Crossfit warmly welcomed me both coaches and members! A amazing community, very good coaching, a beautiful room, surpassing oneself and fun ! The place to be !
Thanks Laurianne, It was great having you here for the 3 months. We all miss you
Fantastic experience: I always drop into D12 crossfit on my visits back to Ireland from Australia. Since my first visit the couches and members have been so welcoming and I love the atnosphere. Couldn't find a better gym! Highly recommend
Thanks Sarah. You're always welcome.
Positive experience: There for a weight lifting competition, brillant day lovely friendly people but bleeding freezing.
Fantastic experience: I worked out 4 times a week for 3 months in preparation for joining CrossFit and I still can barely finish a workout. It's not just a gym it's a community of good people who come together to put in the work and lift each other up. The coaches are incredible and they get in touch with you if you haven't shown up because they want you to improve. I'm often quite hard on myself but always thankful for showing up
Fantastic experience: My favourite place to go after a hard day in work. The coaching and wods are incredible but the community and support reaches far beyond any other gym. Best little gym by far.
Fantastic experience: Best decision I ever made for my fitness was to join D12 CrossFit. I’ve never looked back. Coaches are the best around with a real passion to help you reach all those big and small personal goals, and it helps that their sound too! So proud to be part of an amazing club!
Fantastic experience: Fantastic gym so welcoming
Fantastic experience: Amazing coaches, excellent gym.
Fantastic experience: Best little gym! Very welcoming and knowledgeable trainers. The workouts are different every day and suitable for every level of fitness. Been here over a year now and still loving it!
Fantastic experience: Awesome little gym! So welcoming and the craic is 90! Surprising myself everyday in there... and Dobby is King!!! #Dobbythedoggie
Fantastic experience: Joined as I am a complete beginner to the CrossFit world and was welcomed with open arms and a training plan that suited my complete lack of experience all the while training alongside other who have been there for years. Staff are top quality and explain each and every detail while watching over you each session. Classes throughout the day that mean you never have to be miss the chance to better yourself. Would highly recommend Alan and the crew.
Fantastic experience: I would definitely recommend joining D12 CrossFit! Great atmosphere, excellent coaches and very professionally run! 5 stars!
Fantastic experience: I joined D12 Crossfit approximately 18 months before lock down. Although I had enjoyed my membership in other gyms based in the Tallaght area I was no longer motivated by the fitness classes and individual training in those gyms. From the outset I found the coaches & culture in D12 Crossfit & D12 Weightlifting to be welcoming, encouraging and motivational. The morning classes at 06.00 & 07.00 suited from when I was in the office. The lunchtime and evening classes at 15.30, 16.30, 17.30 & 18.30 suited from when I needed to work late. There is always time slots available and the classes can range from 2/3 up to 15 members at a time. The coaches explain the workouts clearly and ensure that you stretch and work on mobility prior to the workout. The coaches themselves are friendly, approachable and do the workouts themselves. The individual members range in age and backgrounds. From GAA, Rugby & Soccer players who are looking for additional conditioning to couch-potatoes like myself who need encouragement. All members do the same ‘group’ workout and they are tailored for the fitness freaks as well as those who have not been in a gym in years. There is a real community feel & spirit in D12 Crossfit & D12 Weightlifting with frequent in-house competitions, bbqs and social outings. D12 Crossfit & D12 Weightlifting is more than just the #bestlittlegym it is a open & welcome community.

Fantastic experience: Great gym with a group of coaches and members that makes you feel like a part of the team I was new to CrossFit and had never done Olympic Lifts before.
