Frequently Asked Questions

Not at all. Box & Burn is an all-round training gym, not just a boxing gym. While we offer boxing fitness and coaching, most sessions combine strength training, conditioning, and functional fitness. Everything is coached and adapted to your level, whether you're a complete beginner or experienced.

We specialise in small group personal training and 1-to-1 coaching, combining strength training, functional fitness, sled work, and boxing conditioning. We also offer gym memberships, fitness classes, and boxing sessions, giving you a well-rounded approach to building strength, fitness, and confidence.

Most of our sessions are fully coached to ensure you train safely and effectively. We also offer gym memberships for independent training, but our focus is on structured, purposeful sessions that deliver real results.

Just bring comfortable training clothes, trainers, water, and a towel. If you're joining a boxing-based session, gloves can be provided for beginners, but we recommend getting your own once you train regularly.

Yes. We offer both 1-to-1 personal training and small group personal training. Our programmes are designed around your goals, whether that's fat loss, strength building, fitness, or improving boxing skills.

Would highly recommend to anyone that needs to be motivated and supported to achieve their fitness goals. There's a variety of memberships available, various classes throughout the week and the opportunity to have 1:1 or small group PTs with one of the amazing coaches. Lee & MJ go over and above to support, guide and motivate and do it all with humour, warmth and a genuine passion for getting the results you want 👊🏋🏻‍♀️💪🥊

Joining this gym is the best decision I’ve made this year. Lees knowledge is incredible and thanks to his help and advice, I’m fitter healthier and happier. The trainers at this gym will work with you on any injuries you have, give you nutritional advice and motivate you to reach your goals. This really is a place for anyone with any goal, including those with experience, but in particular for beginners I would recommend. It’s a gym for people that don’t like gyms! The classes are fun, the membership is priced more than reasonably, access is easy and everyone is friendly. Highly recommend, you wont regret it.

I've tried various gyms and exercise classes in my life, but never stuck at anything until I started coming here. The classes are varied, fun and always challenging. The boot camps are a great way to kick start your fitness. Lee and MJ give great advice and the other gym goers are friendly and supportive. There is a mix of ages and fitness levels, and all are welcomed. I no longer think of exercise as a necessary evil , but dare I say it, is now something I actually enjoy. I cannot recommend Box N Burn enough.

This is a great gym, with amazing PTs and has so many friendly members that also train there. The high energy classes have challenged me to work harder and also have fun whilst working out. Lee and MJ are always on hand for help and advice on training programmes, and support. I've had a couple of PTs with Lee who has a great deal of knowledge on technique and helping you hit your goals. There's free parking on site and a great view of the marina from the gym. No matter what level of fitness you are at, it's a very comfortable environment to be in and a great place to meet new people. I highly recommend this a place to either start your fitness journey or to get back into it!

Joining this gym is the best (health) decision I've ever made. I joined in January and took part in an intense 4 week course to kick start my fitness and weight loss journey, I enjoyed it so much I am doing it again. The course isn't just about relentless exercise but also offers proper advice on nutrition and eating well (without restrictions), repairing those ridiculous relationships we have with stupid diets. Lee and MJ are absolute diamonds. The support and encouragement you get is unreal nothing is ever too much for these two. They will push you hard but believe me you will get results. The gym plans are so personal, these guys know that one size does not fit all but they will make it work for you. You can join in with any of the fitness classes or if you prefer you can workout on your own. There is something for everyone. One of the best parts is a sense of community and friendship amongst the other gym members, literally anyone will help and encourage you here even if they don't know you. You need a spotter? just ask, a work buddy? you got it. 💪 If you're thinking of starting a journey for fitness or weight loss or both you should definitely join here.

I’ve recommended this to my friends already. I’ve been a member for over a year and have never been so happy! MJ and Lee are amazing PT’s, they are supportive, encouraging and give great advice. The private PT, group PT and classes are all ace. I love the community spirit, everyone is so friendly and kind! It doesn’t matter what fitness level you are at, they support you! I’ve made some amazing friends.

BEST GYM EVER!!!!!! I have always found gyms quite intimidating when going to a class ect on my own, but lee and mj are such good PTs that they make you feel at ease and everyone is so friendly. My fitness has come such a long way more so than when I have used any other gyms. Lee always makes sure I’m doing certain exercises correctly and makes every class fun. I would go as far as to say I now love exercise 🤣

Have been using Box and Burn for nearly 3 years now, it is undoubtedly the best gym around, The knowledge of MJ and Lee is second to none, and they are always on hand to help or advise. The classes are great and filled with a great mix of people who always make you feel welcome. I travel from Hove although is abit of a distance I wouldn't go anywhere else. 😁

I love going to Box and Burn gym. I’m currently doing their Box N Burn course. The personal trainers run fanatic classes that push you to reach your goals. I have reached so many PB’s from all the challenges that are set. This has boosted my confidence in believing I can still do it. I can’t remember achieving so much in such a short space of time.I’m feeling great 3 weeks into the course 1 week still to go. My confidence levels are overflowing. Can’t wait for the next course.
