The home of fitness in Norwich

GAIN Fitness Norwich offers so much more than a conventional CrossFit gym. As our timetable illustrates, CrossFit is our core business but not our sole offering. We also deliver HIIT, Olympic Weightlifting, Gymnastics, Rowing & Bespoke Personal Training.

Our goal is to meet everyone’s fitness needs, from complete beginners to performance athletes and everyone in-between. We want to know what makes YOU tick and ensure you have everything you need.


CrossFit (CF60)

A CrossFit class usually consists of a strength/skill element followed by a high intensity workout. Come along and experience a professionally programmed and coached class where you’ll be sure to improve your health and fitness every session.



Our HIIT classes (FIT60 & FIT45) are 60/45 minute classes which involve no barbells or advanced gymnastics. Expect 2-3 short workouts per session of high intensity interval training involving running, rowing, biking, bodyweight movements, kettlebells & dumbbells.



Our barbell classes at GAIN Fitness are designed to improve your understanding and technical ability of Olympic weightlifting. We’ll focus on the snatch and clean and jerk, whilst also working on squats, presses and pulls. A great class for anybody who wants to improve their barbell technique for CrossFit.



This class will look at breaking down the gymnastic movements used in our Crossfit workouts, allowing you to work on progressions without the pressure. You will work on movements such as handstand push ups, handstand walks, ring and bar muscle ups and pull ups. It will also work predominantly on core strength which will help you in all other movements and reduce the risk of injury.


CrossFit Kids

GAIN Kids is a fitness programme offering CrossFit and Gymnastics to ages 4 to 15 years old. We focus on the many disciplines of fitness and no two sessions are the same, keeping classes fun and inclusive. Once your child reaches 16 years old, they are ready to start their GAIN fitness journey in the adult classes.



If you feel you could benefit from some 1-2-1 training then our personal training services are ideal for you. These sessions can be designed to improve all aspects of CrossFit as well as general health and fitness. Contact us today to discuss further.

Karlton Gray

Incredible facilities - so much room for activities! 😝 but thought goes into every area - changing rooms, café communal area and on the gym floor the classes are able to be spread to run simultaneously without issue. All the coaches are great, encouraging and push you to do the best you can. So much support from other members too, a really great bunch of people. So many different classes and you can push yourself to athlete level or just turn up and have a fun workout - there’s something for everyone. Lots of regular socials organised too 👍🏼 Zero regrets joining Gain, it’s a great place to train and have fun!

Lindsey Beard

The most supportive sporting atmosphere I've ever been a part of and ever imagined. Brilliant coaches who all will give their time to help out anyone who needs it, whether you want to have some fun, lose a little weight, or compete in crossfit. This comes with the members who will lift you up at every opportunity. It's the best hour of my day.
