GDN Gym - Personal Training and Group PT - Chalfont Saint Giles

I’ve been coming to GDN for 6 months and it’s been incredible! I really look forward to the class every week. I do the hockey strength and conditioning classes and my hockey skills have improved so much. It’s great doing specific workouts to improve my game as well. The team are all so lovely, it has a really nice community feel and the gym is so nicely designed.

I've been training at GDN for just under a year, and it's hands down the best gym experience I’ve had. The atmosphere is spot on—friendly, motivating, and never intimidating. The equipment is top-notch, well-maintained, and there's everything you need for a solid workout.

The real game-changer for me has been my personal trainer. The level of support, knowledge, and encouragement they bring has completely transformed the way I approach the gym. They've kept me accountable, pushed me when I needed it, and helped me build a routine that actually sticks. This is the longest I’ve ever been consistent in the gym, and that says it all.

If you're looking for a gym that feels like more than just a place to work out—somewhere you can actually enjoy training, see results, and feel part of a great community—GDN Fitness is the place to be. Highly recommend! 💪🔥

I have been going to GDN since 2022 and absolutely love it! It's a great local
gym, fantastic range of equipment and whatever their trainers lack in sense of humour they more than make up in professionalism! There is a real sense of community and we love attending their parties. Thank you, keep up the great work!

GDN is a superb, friendly and brilliantly equipped gym. I’ve been attending Iain’s hockey strength and conditioning classes for a couple of years now and not only have my hockey skills improved in leaps and bounds but I’ve also suffered far fewer injuries over the course of the season. Iain and his team are really knowledgeable and the classes are great fun. If you’re thinking about going to GDN, stop thinking and get booking, you won’t regret it!

I joined GDN Gym in November 2024, and after nearly four months, I can confidently say it has been an absolutely amazing experience! From the moment I stepped in, I felt welcomed, supported, and motivated to embark on my fitness journey.

The gym itself is top-notch—immaculately maintained, well-equipped, and designed to cater to all training needs. Whether you're into strength training, functional workouts, or general fitness, the variety of high-quality equipment ensures that every workout is effective and enjoyable.

A special shoutout to Iain, my trainer, who has truly transformed my experience. Being completely new to the gym, I was initially unsure of what to expect, but Iain’s expertise, patience, and encouragement made all the difference. His personalized approach, attention to detail, and ability to push me just the right amount have helped me gain confidence and make real progress. I genuinely couldn’t have asked for a better trainer!

If you're looking for a private gym that prioritizes quality, guidance, and a positive atmosphere, I highly recommend this one. Whether you're a beginner or an experienced gym-goer, this is the perfect place to achieve your fitness goals!

I’ve been going to GDN fitness for about 8 months now and it’s easily one of the best gyms I have been to. The small group personal training classes are the best, if you want to train with others (great for competitive edge) but not be lost in class with 20/30 odd people. The PT’s are very hot on form and safety, which means they are guiding you throughout the class and the results are evident on how strong I have gotten in the last 8 months. It feels like I am party to a friendly and great community as you get to know the others in the class, when you are in the small size as 6 (Max).

I will highly recommend to any of my friends without any hesitation.

This beautifully designed gym is an absolute joy to train in. From the stylish interior design to the state-of-the-art equipment, everything is thoughtfully put together to create a motivating and welcoming space.

The coaches are fantastic—knowledgeable, encouraging, and always pushing you to get the best out of every session. The group classes are a perfect balance of strength and cardio, keeping workouts engaging and effective. Personally, I’ve seen a real boost in my own fitness levels. Even on days when I don’t feel like working out, I always leave class feeling better—energized, accomplished, and in a great mood.

If you're looking for a gym that combines top-tier training, a supportive community, and a beautifully designed space, this is the place to be. Highly recommended!

I joined GDN in 2023, and honestly, I’ve never looked back! At 50-something, I was totally out of shape and the thought of stepping into a gym was terrifying. But from the moment I walked in, I was welcomed by Iain, Emma, and the amazing team, who were all so patient, encouraging, and full of knowledge.

Fast forward to now, and GDN is a regular part of my routine. I’ve not only gotten fitter, but with the help of the team my bingo wings have disappeared 😂! (Not even kidding).

The best part? I’ve discovered that the gym can actually be fun! Whether I’m breaking a sweat or laughing with the crew, I’m always learning and improving. Thank you Iain , Emma Oscar & Josh
