CMB was founded for one reason: to improve the quality of personal training in Dublin. We realised there was a need for a private gym - something with the size of an old-school independent gym, but with the facilities and equipment of a modern place. Dublin is a thriving place to live, and the people here deserve the best expertise and a great place to train.

CMB’s founder Darragh Hayes had spent a lot of time abroad, firstly as a soccer player and then as a fitness model. He got to train in some of the best fitness facilities in the world. He saw how these places gave the customer an unforgettable experience, and he brought that back to Dublin.


  • Excellence - in our coaching, facilities, training, and services

  • Knowledge - we keep learning so we can pass it on to you

When you step through the door of the gym, you bring with you hopes, dreams, goals, and a passion for change. We promise to match that passion. Come and visit CMB Gym in Dublin and meet your new favourite fitness facility.



Darragh Hayes started CMB as a Personal Training business in 2007. He opened CMB Gym in Dublin in 2012 after visiting some of the best fitness facilities around the world and discovering the elements they all shared. He soon realised these factors were at the heart of every good results-based gym.

CMB quickly got a word-of-mouth reputation for being cutting-edge, not just in facilities and equipment, but in the remarkable results it was getting for clients.

There’s nothing average about CMB, which is why we don’t attract average people who want “just” average results. Everyone who trains here - men and women of all ages from teens to 60s - wants something more. More muscle mass, better condition, improved health, more strength. (They end up getting more confidence and happiness, too!)

Today, CMB is a familiar sight on Upper Fitzwilliam Street. We’re open 7 days a week and you’ll see a range of people coming in and out of our doors, from VIPs and high-flyers to local folk who know a good thing when they see it.

We’re not going anywhere, so come down and see what we’re about. You’ll always be welcome.
