CrossFit Decennia was created out of our passion for helping people achieve a solid foundation in their health and fitness.


Our coaches have over 25 years of combined experience in the fitness industry and use this experience to provide our members with the tools necessary to really make a difference.

We’re here to help you get fitter, stronger and faster and to look and feel better. We pride ourselves on the quality of our coaching, so to ensure that you receive the attention you deserve, we keep our classes small and our experienced, knowledgeable and friendly coaches will help and guide you in detail through every session.

We want you to become the best version of yourself and want you to have fun whilst doing it. You will never be on your own and you will always train in an environment that is encouraging, supportive and friendly.

Our gym is based in the popular Portslade area of Brighton, East Sussex and is conveniently located near to Portslade train station. We have over 30 classes a week offering CrossFit & Olympic Weightlifting training with hassle free, no-contract memberships.

Our Address:

Unit 3, Carlton Terrace, Boundary Road, Portslade, BN41-1XF

Getting Here:

CrossFit Decennia is located in Portslade, Brighton, inside Fishersgate Boxing Club, in the units behind North Star Cars. Take the turning for the units off of Carlton Terrace (the last turning on the left before the traffic lights on the A270 if you are heading north) and take the first left into our car park. You can park in any of the Boxing Club reserved spaces or in front of the shutter doors. If there is no space in the car park you can also park for 90 minutes in Aldi car park which is two minutes along Carlton Terrace or the Tesco car park for unlimited time which is 5 minutes along Carlton Terrace. There is also free parking in Hallyburton Road (and any of the roads off of it) and Hangleton Road.

You will then need to walk out of the car park and turn left, or just straight down the driveway if you are walking in, and go past 'Revive' car specialists on your left. Keep walking to the bottom of the driveway and just before you get to the BT car park and at the end of the units, turn sharp left. We are just along the pathway and you will see a sign above the door. We are a little bit tucked away so give us a call if you cant find us!
