GDN Fitness

Fantastic experience: GDN Gym is absolutely amazing! The personal trainers are fantastic , so knowledgeable, supportive, and always willing to share tips that make a real difference. I love how the classes are small, which means plenty of guidance and it never feels overwhelming. Booking PT sessions and classes is super easy and straightforward, which makes it really convenient for me to stay consistent. The atmosphere is friendly, motivating, and welcoming . I always leave feeling stronger and more confident. Couldn’t recommend this gym enough :)

Fantastic experience: I have been a member of this beautiful Gym nearly on my third month, and I never looked back, the staff are incredible highly qualified, very friendly, they helped me through my journey of getting fit again, am more confident now the way my body looks now and its never boring for me going there, because the place is like little SPA, beautifully designed, honestly it’s like hidden gem, in leafy bucks. But the only thing I find it challenging is their car park, it’s a bit small size , but somehow they manage! and am getting used to it Highly recommended.

Fantastic experience: GDN is a great gym. The staff are very welcoming and encouraging and they always create an environment that is not intimidating at all and people can work out in a well structured way but still at their own pace and level. I would definitely recommend going to check it out for yourself.

Fantastic experience: Absolutely love this beautiful gym.

Fantastic experience: Really well structured sessions and a great work out for all levels!

Fantastic experience: When I started out with the fitness and hockey programme at GDN I was excited and easily impressed with the high quality gym; staff who are enthusiastic, clearly knowledgeable and sufficiently pushy to achieve personal goals; and the fantastic on-site hockey training pitch. However, I still remained sceptical of the personal impact and whether I could commit within a busy work schedule. Almost a year on, I could not be more happy with the results - I’m stronger, fitter, injury-free, and have learnt so much about my own fitness conditioning. My hockey stick skills have improved and I’m still learning new tricks, which have noticeably enhanced my game. Whilst always a scheduling challenge, my weekly sessions at GDN are an absolute priority and easily recommended.

Fantastic experience: Everything about this gym is wonderful - the team, the vibe, the equipment, the music. Iain and Ish have created something really special here - highly recommend!

Fantastic experience: Iain, Ish and their team at GDN are a class above; welcoming and knowledgeable, knowing exactly how far to test one’s endurance. All of this in their purpose-built gym in a fabulous location. GDN eventually become an integral part of your life and DNA.

Fantastic experience: Have been having PT sessions at GDN since May 2019 and have worked with several members of the team over the years. I've never been a sporty type but I have recognised as i'm getting older taking care of yourself is important and I look forward to my sessions and i've stuck to it.. As someone who is now in their 50's I feel great.. Better than when I was in my 30's! Big gym's for me can be quite intimidating and also souless... The setup at GDN is great, intimate and I feel vauled.. I cannot recommend them highly enough.

Fantastic experience: I try to use GDN at least once a week, I find the sessions very helpful for maintaining fitness and skills levels. It is always very relaxed but always professional

Fantastic experience: I have been going to GDN since mid 2022 for hockey strength and conditioning. Excellent training and coaching led by Iain. I like the fact it is small local "niche" gym, really well designed, with great facilities and they are a friendly team of coaches who are very competent and professional. It's a pleasure to train there!! Need I say more?

Fantastic experience: I joined GDN in June 2024 opting for personal training to improve my health and fitness, after 47 years of not really taking care of myself. I opted for one 1-2-1 session a week and was also given a plan for 2 extra workouts so I could do them at my own gym nearer my home. Being a novice, the plan and 1-2-1 sessions really helped me to improve my overall strength, health and endurance. I have lost weight, become stronger, put my diabetes into remission and am much more comfortable in my own skin. Would recommend GDN.

Fantastic experience: I can’t thank Iain enough for his incredible support and guidance throughout my short fitness journey. He knows how to push me in just the right way while always bringing great energy to every session. If you’re looking for a trainer who knows his stuff and genuinely cares about his clients, Iain is your man!

Fantastic experience: I was guided to GDN Gym, through an Instagram ad over Christmas 2024 at a time where I was back in the UK for a short period and was in need of a flexible, no contract, aesthetically pleasing boutique environment to train. The whole process from signing up to talking through my requirements with Iain, PT assessment and sessions with Emma and subsequently throwing myself into group PT classes instantly over 2 months, with the pleasure of training with all of the team Iain, Emma, Josh and Oscar has been the best gift to myself! All of you at GDN have been super welcoming, encouraging and dedicated to providing a seamless, energetic, functional, professional training sessions each week. The consistency in delivery amongst you all has been recognised. Credit to Ishani, the creative behind the design, interiors and styling. You are truly talented! Honestly, so much gratitude and good energies out to you all, until I'm back...Simply Be You!

Fantastic experience: 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!

Fantastic experience: I have been using GDN since it’s inception, good fun, great coaching, well worth while for any standard of fitness or hockey.

Fantastic experience: 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!

Fantastic experience: 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!

Fantastic experience: Incredible place to train. Everyone is so friendly and they do really push you. Would recommend it to absolutely anyone. Have been going for about 3-4 years now and enjoyed every second of it!!!

Fantastic experience: I love it at GDN! The quality of the training delivered by the coaches is excellent. I love training in the small classes alongside the other friendly members and I always look forward to going back.

Fantastic experience: A beautifully designed gym that wouldn’t look out of place in a luxury hotel with friendly and encouraging trainers. Would very much recommend.

Fantastic experience: 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.

Fantastic experience: GDN are a real training find. Great gym. Oscar, you are a star

Fantastic experience: Can't recommend this place highly enough! Great facilities with super friendly and professional staff. I've loved every personal training session I've done here. My trainer, Alex, has been brilliant. Overall, worth every single penny.

Fantastic experience: Best people for the job. Always focused on you and what’s right for your individual workout. Also helps a great deal that they’re all extraordinarily friendly and genuinely welcoming.

Fantastic experience: Fantastic space with excellent, knowledgeable and friendly personal trainers! All workouts are super fun and Iain pushes me to my limits every single time

Fantastic experience: My partner and I are so happy to have come across GDN Fitness :) Our personal trainer, Iain, is one of the nicest people I’ve met, always listening to me and my needs, whilst constantly providing sound advice and great expertise. Can’t believe how unfit I felt, mentally and physically, only just weeks before training here when I felt there was no hope for me! Best investment ever, as health is wealth

Fantastic experience: I absolutely love training down at GDN it’s such a lovely gym! All the staff are super friendly and the gym is so well equipped and also so clean and fresh! I train with Alex who is absolutely fantastic and has helped me become stronger fitter & more confident!

Fantastic experience: I have been training with Emma for about 7 weeks and am feeling the benefits already. Each session is always slightly different, keeping you on your toes, and her knowledge and support is second to none. The equipment is always well kept and clean and the space is beautiful. There are only ever one or two others training at any one time, with all the trainers offering support with a smile. Could not recommend enough.

Fantastic experience: I began strength training with Emma last September. I'm not looking for bulging muscles, just long and lean muscles and to strengthen and tone generally. Emma is supportive, fun and over the time we have worked together, has become confident in my ability, which means she can push me to do more and doesn't let me off the hook. I can honestly say I have gone from strength to strength. Taking that hour twice a week, out of my busy schedule, gives me much needed breathing space and keeps me fit. I'm addicted! I should also mention, the gym is light, modern and clean and is furnished with the latest equipment.

Fantastic experience: Amazing space, dedicated and knowledgeable team and great atmosphere

Fantastic experience: L'équipe GDN est incroyable, j'ai vu beaucoup des vidéos en ligne et j'ai essaie de m'entraîner à suivre vos vidéos. J'ai hâte de vous rendre visite en personne.

Fantastic experience: A really stylish and modern gym with a great range of equipment. The team are really friendly but very professional. Definitely recommend!

Fantastic experience: Excellent training sessions, top class facility without the feel of a corporate gym. Thoroughly recommend.

Fantastic experience: Clean and professional space with attentive, knowledgable and caring instructors. Would really recommend this place to anyone!

Fantastic experience: A well worth five star place , I've been following through Facebook and Instagram , professional and amazing team.

Fantastic experience: Great facilities and professional trainers, would definitely recommend.

Fantastic experience: I’ve been working with GDN now for just over two months and the results speak for themselves - with GDN’s help, I am currently symptom-free, having been plagued with nerve problems and stiffness in my lower back, for the first time in 13 years! The staff are so personable and attentive; the facilities are top drawer and most importantly Covid-secure. Setting goals with specific sport and personal challenges in mind was easy and each session is as enjoyable (if not tougher) than the last.

Fantastic experience: The dedicated hockey goalkeeper sessions are fantastic. It's so logical to have GK-specific gym sessions to replicate goalkeeper movements but I wasn't aware that anyone did this until we found GDN. An hour in the gym followed by an hour on the mini pitch, to put it all into practice, makes for a great session. My daughter has made significant progress in just a few sessions.

Fantastic experience: I’ve been going to GDN for over a year, and I’ve been motivated ever since! Working out with the team has helped me keep fit for my Sunday league games consistently. Even during the lockdown, GDN’s commitment to health allowed me to benefit from online sessions.

Fantastic experience: A great pt gym with amazing decor. Professional and friendly. Alex always pushes me out of my comfort zone to achieve great results. Always supportive and motivational. Highly recommended.

Fantastic experience: This is an incredible space, you'd hardly know it was a gym. The staff and trainers were extremely professional and attentive. The equipment is very high end and the hockey pitch at the back of the gym is perfect for small group training and close skills. Would recommend to anyone looking to get fit and improve their hockey skills!

Fantastic experience: I've always struggled getting into exercise and hated working out in my old gym. Since joining GDN, I look forward to every session! The space is beautifully designed and the team are so welcoming and I always leave feeling rejuvenated with a sense of accomplishment. Great experience

Fantastic experience: The GDN gym is a great, spotless and well organised space, with excellent covid precautions. Had my first PT session with Alex four weeks ago after having concerns about my form on certain exercises and also about not having any real structure or plan to my workouts across the week. Whole session felt completely personal and bespoke and Alex really knows his stuff. A solid workout in itself, the session taught me new exercises and how I should change certain things that I had been doing for ages. Alex then set me up with an incredible fitness plan for the forthcoming six weeks and sticking to that has seen incredible results. Looking forward to my next session and would wholeheartedly recommend Alex and the GDN setup as a whole for anyone wanting guidance or structure for their health/workout plans.

Fantastic experience: GDN Fitness is a very well equipped and beautifully designed PT gym. It has everything you need to get a good workout in! They have done so well in adapting to covid, with your temperature being checked as you walk in and having sanitation stations all around. The whole team is absolutely fantastic, so welcoming and friendly, definitely makes the hard work, fun! I would recommend GDN to anyone who is looking for a PT, but also looking for a safe and friendly space to have sessions during covid.

Fantastic experience: I am a Hockey Goalkeeper Coach, and have referred several players to GDN to develop Strength and Conditioning to improve their overall game. GDN provide a bespoke programme, with incredible facilities and brilliant trainers to match. The levels of improvement in pitch performance achieved by all my goalkeepers as a consequence has been remarkable. Highly recommended.

Fantastic experience: Sessions here at GDN are always a highlight in my training calendar. A relaxed and focussed environment with an attention to detail keeps me coming back.

Fantastic experience: I have trained with Alex on regular basis for years, really like how he runs the 1:1 PT sessions and his approach to support clients fitness goals.  Few months after the beginning of lockdown however , I had to make the difficult decision to stop my virtual PT sessions due to personal circumstances. After months of inactivity,  GDN online group sessions have been a life saver!  They have allowed me to gradually build up strength again.  I feel much better and have lost a significant amount of weight since I started to add the sessions to my week..   Thanks to GDN online program, I am enjoying my regular session with Alex,  have also joined sessions with Iain and Emma,  both excellent coaches as well. I am still not 100% comfortable with getting back to the gym in person after COVID, but hoping to resume my 1:1 session with Alex at some point later this year.  Thanks GDN team!

Fantastic experience: I have been to GDN fitness a few times now and i’m always welcomed with a warm smile by all staff members. The decor at GDN is lovely and I always feel a sense of calm when I visit. Alex has been helping me on my fitness journey, explaining my goals to him and both working on a plan to achieve this. There are times you feel you “can’t” but he works you through it and motivates you to keep pushing. Would highly recommend GDN

Fantastic experience: Amazing facilities and training session

Fantastic experience: Amazing space to work out in; bright, clean and well equipped. Alex is a fantastic trainer and the whole team are friendly and welcoming. Private parking and shower facilities available.

Fantastic experience: Fantastic few sessions with Iain - both the fitness and hockey side is excellent. Great set up. My boys (11/8 at the time) also had a session and really enjoyed it. Fully recommended!

Fantastic experience: A tranquil and peaceful environment which is very well laid out. I found it very clean and covid aware; with temperature checks at the door and sanitation stations, my mind was put at ease. The staff are all very friendly and professional. They provide fun and well instructed classes, adjusting to individual abilities to ensure you get the most out of each session. Definitely an environment I would recommend to others. Can't wait for my next class!

Fantastic experience: For those of you who hate exercise, going to the gym, training and virtually any aspect of sport (that would be me in all respects) - allow me to guide you towards GDN Fitness and Hockey. Well I would, wouldn't I...? since I've been training with Iain Gordon for several years - and stuck with it several times every week overcoming a life time of good intentions incinerated on the pyre of inertia. In lockdown I was denied my regular sessions - but Iain and lovely wife Ish, enterprising types both, put together videos to be followed daily. Unlike the plethora of similar offerings online - the GDN Fitness way is one of calm, but determined guidance - no competitive shrieking or pounding background "music" here, no matey bonhomie - these are people you might actually want to invite into your home. So Google them up - GDN Fitness on Youtube or Instagram - and if I can stick with it, believe me: anyone can!! If you are based anywhere on the Metropolitan Line beyond Wembley, go see them at the really cool studio they have in a tranquil rural setting near Chalfont St Giles. Stay Safe, stay sane!

Fantastic experience: I love training at GDN! I have been training with Alex for 5 years and throughout that time he has continued to increase his knowledge and service, so was happy to move with him when he started working at GDN. Walking through the door it feels like you are walking into a posh spa, it is so beautifully decorated and designed, yet don't be fooled, it is full to the brim of all the equipment and expertise you could need. And it has such a friendly welcoming vibe. I can't wait for my session each week!

Fantastic experience: This gym is FANTASTIC. A small, family run business that is doing everything right. The equipment is high quality, it looks beautiful, and the classes have small numbers, a high intensity, and a personal touch from Iain. Iain really knows his stuff, and helps with mobility, stability and strength training which is sport-specific. Once you try out the classes, you'll see how Iain really goes above and beyond what's expected of a PT and his knowledge really shines through. The only regret you'll have is not trying this place sooner.

Fantastic experience: Had a wonderful group class coached by Emma last Friday. The mixture of a very sleek gym, coupled with Emma's motivation helped me really work hard in the session. Took advantage of the intro offer (£50 for 4 sessions), and will certainly be booking more once I've exhausted those. Highly recommend!

Fantastic experience: I took advantage of the Introduction offer of 8 classes for £79 which was extremely good value for money. Great to have small classes and to have so much variation in each class. Iain took time and care to adjust exercises according to your personal objectives and your capability whilst still challenging you to push yourself. Beautifully designed environment to train in too. Highly recommend.

Fantastic experience: GDN Fitness is a FANTASTIC personal training gym. It feels like you are walking into a 5 star hotel !. I have personal training with Emma who specialises in Tennis Strength and Conditioning. Each session is aimed at helping me on court and she works in blocks of 4 weeks, so you can really see the difference and improvement in each session. I am lifting weights that I never thought I would be able to do and my fitness and movement on a tennis court is the best it has ever been. Not only does the gym look and feel lovely, it is super friendly and being anxious about the current Covid-19 situation, I feel totally comfortable as their protocols are very robust !!. There are amazing outdoor training areas which Emma mixes in to my sessions, something I have never done before and the fact you are exercising outside, really lifts your mood. I would 110% recommend GDN Fitness.

Fantastic experience: I can only say good things about this place. Iain is an amazing trainer and great person. The rythme of his class is perfect, it's challenging and good for all level. He knows perfectly what he is doing and would adjust the workout for you. The classes are in small group which I love. The place itself is beautiful, designed with style and well thought out. It's also fully equipped and very clean. I loved it. Don't think twice, go try.

Fantastic experience: Immaculate facility with friendly and knowledgeable owners

Fantastic experience: Highly recommend this gym. Very knowledgeable and attentive - the classes are great and the gym itself is a great environment to be in.

Fantastic experience: Amazing facility, and a modern fresh approach to fitness for busy lifestyles.

Fantastic experience: Cool new gym in area. I’ve had back problems for a while and have found the upper body strength classes have really helped. Classes are small and the teacher is really friendly and knowledgable. He spent time with me before I started the classes to understand my injuries and advised how building up core strength would help. I don’t play hockey but the hockey training pitch looks great too!

Fantastic experience: Great PT sessions with Iain. I've had knee issues (ACL) in the last few years and he took some time to test my movements and strength before we did the sessions. Really enjoyed the sessions and my knee feels much better now, strong recommend!

Fantastic experience: Fantastic setup. This is ideal for those looking to put their children in hockey and don’t want to put them in a club straight away. My son has been playing for the last 10 years, if this setup was around back then, we would 100% got Ian and Ish to carry out personal coaching sessions building all the right skills prior to joining a club. If you are aiming for County and JRPC then this Centre is well worth the visit. The centre is also great for those looking to have personal training sessions and not really wanting to join a gym.

Fantastic experience: Dear Iain, When my son, Rowan, made the decision to apply for the Royal Navy he knew he would have to get himself in shape to pass the physical test which formed part of his entrance criteria. Rowan did have a fairly decent base line of fitness from his mountain bike riding and downhill racing however we knew he was weak in other areas and he wanted to improve on these. At first he was a little skeptical and, in his own words, said “I don’t want to be in a old mans fitness class”. This fear was soon allayed when he saw the photos of the impressive gym set-up and yourself, a living, walking, breathing advert for what can be achieved! The goals you set really pushed Rowan but he absolutely loved the sessions. He was pleasantly surprised that with the measured approach you took he could see the improvements he was making in a relatively short timescale. Subsequent to the training with you, and the plan you gave him to work on in the gym, he comfortably passed his fitness test for the Royal Navy and is looking forward to a new future career with them. Thank you. As a by-product of Rowan’s new found fitness he is now also riding his mountain bike faster and for longer, much to the frustration of his friends. A good few of them are now making noises about training with you and I for one would highly recommend that they do. Kind regards Nathan Mincham
