I have worked with Julien for some time and consider him to be very professional and knowledgeable in his fitness instruction.
He is considerate, but does not compromise because of age, and ensures that each client receives the maximum benefit from every lesson.
To be recommended.
I am most grateful.

I ate throughout lockdown and put myself in a prison of food to numb out. I was 21 stone.
Now 15 stone. Julien, as a PT has humanity, skill and walks the talk.
Now: clarity, compassion and a 360 degree focus on my spiritual, emotional and emotional wellbeing.

Julien has helped me since I have given birth. I wanted to get back into fitness but wanted to do it safely and securely. Julien is very reliable in his field with a wealth of postpartum fitness knowledge.
Julien’s sessions helped me get back into shape, but most importantly made me feel stronger again both physically and mentally.
Julien is both fun and beneficial and I highly recommend him to anyone that has just had a baby. He is also very comprehensive. For example, last week when my baby got sick I was able to reschedule my session easily with him.
Julien is flexible and can move things around for his clients, taking in their needs regarding their babies and child-rearing responsibilities.

Julien has been my PT since November 2019. He is professional and a pleasure to work with. He understands my training needs and can adapt these to a level that feels comfortable but challenging. He can also develop good trainer - client relationships, enabling me to trust him to help me achieve and maintain my short and long-term fitness goals.
I work as a counsellor/therapist/clinical supervisor and support others with their emotional wellbeing. Julien take cares of my physical well-being. He is a good listener, able to adapt his training to fit how I may be feeling on any particular day. One of the reasons I choose him to be my PT is that I saw how he works in the gym and liked the way he was attentive and at ease, but focused, on the needs of his clients.
Julien’s sports experience is reflected in his approach to training which suits my needs to improve and maintain my strength, cardiovascular fitness and flexibility. I value the knowledge, skill, and motivation that he brings to each session and would highly recommend Julien as a personal trainer.

Training with Julien has always been fun and exciting. His functional method has made every workout a great challenge and helped to push me closer to my fitness goal.
I would happily recommend him to anyone who wishes to improve their fitness life.

Having a personal trainer has always been a huge priority for me and my personal development, alongside my day to day living, and has proven to be fiercely rewarding on many levels!
For me, training with Julien has been vitally important for many reasons.
A ‘one to one’ intensive exercise regime, twice-weekly has worked wonders for my overall health, general appearance and physical demeanour.
Parallel to this and equally important is how it serves my mental health.
I’ve suffered from mental health problems for several years which have been crippling to my functioning as a healthy young male adult, including certified clinical depression and Bulimia Nervosa.
Advice from doctors and mental health experts over the years have all reached the same conclusion (for me personally) that regular exercise along with prescribed medication, work hand in hand to produce good results in keeping my ‘demons’ at bay.
My commitment to the gym has always been paramount, self-motivated and unaided.
Exercising regularly with Julien has generally enhanced and increased my overall results and achievements with a great sense of teamwork too. As Personal Trainers come - Julien is first rate.
Previously I have worked with two PT specialists, both of them producing results, but nothing compared to my work with Julien, which is why I’ve been training with him for several years now!
His empathy towards mental health/working with people of all ages and physical disabilities is a defining quality in Julien's business. His focus on training is varied unlike some other PT experts I have encountered and the package he will design around you will take into account you as a person; your goals, your weaknesses, diet and rest and your lifestyle choices.
I highly recommend Julien to help you reach your life goals, not just physically but mentally too!

Julian’s a thoughtful personal trainer who‘s communication skills are second to none. He always asks how’s your health and physical state before each workout.
His attention to detail whilst in the gym is in attending to every set hands-on, always making sure the exercise is executed in the right way!
For the best results, he is a great trainer to be trained by.

Lawrence Napper
Senior Lecturer,
King's College London
I thoroughly recommend training with Julien. He is gentle but firm, very attentive to good form and pushes you beyond what you think you are capable of, helping you to realise what can be achieved. His philosophy of fitness is refreshing and inspiring because it is based on creating good long-term habits, rather than simply focussing on short-term goals. Foundations laid now with Julien will continue to pay off in ten, twenty, forty years.
When you are in the session, Julien focusses on you and your needs. He is reliable, always on time and ready to start when he arrives. He is also flexible to your timetable or if you need to train outdoors or closer to home.
And perhaps just as important, when you see him in the gym or bump into him in town he is always friendly, cheerful, charming and entertaining, a delight to see, as well as a brilliant and friendly asset to the gym as a whole.

I am 68 years old this year and work for the City of London Corporation. I have been training with Julien Bertherat for almost 12 years. The length of my time with him must speak volumes about the high standard of personal training which he delivers.
For me, his main characteristics are his complete lack of ‘gym inspired’ self-awareness, but more importantly, he has a total commitment to his clients; taking account of their personal fitness aspirations (which he will sensitively ensure are realistic), their ages, current fitness levels and, through his training schedule, their future physical potential.
Julien is firm but fair, meticulous as to the detail and the quality of individual exercises being performed and I have found after all this time with him that he is never complacent. He even now corrects me if I fall short of his high standards during our sessions. Significantly, he has clients of all ages, abilities and a focus on commitment. Julian will see to it that each one of us will be gently but firmly steered toward our potential achievement.

After just a few sessions with Julien I am already stronger, fitter and confident in the gym. Julien's friendly, easy-going personality creates a relaxed, comfortable atmosphere.
Each session is challenging, varied and fun and Julian motivates me to push past my limits to get results. I enjoy every session and look forward to many more!

Ross Childs
Senior Development Manager, LSE
I started to train with Julian when I’d just arrived at Jubilee Hall. I wanted a few sessions with a trainer to get to know the layout of the gym, to get a good programme sorted and to know at least one friendly face in a new gym.
I really enjoyed training with Julian. He’s personable and friendly and I appreciated his balanced approach to fitness. We discussed my goals and Julian helped to ensure that I saw progress in my body without becoming too physique obsessed.
I’d previously worked with trainers who pushed me towards getting the best body possible, without much concern for mental wellbeing.
Today, I really appreciate the balance of the two and I found Julian to be very likeminded with me on this.
I’d recommend Julian if you’re looking to work with a friendly, approachable trainer who will support you in getting into shape sustainably.

Lucy Reeve
Runner
I signed-up to train with Julien for an initial 2 month period, to get me back into the gym and focus on strength and tone.
As a keen runner I've always been relatively fit, but often lose focus and forget to go ‘back to basics' and concentrate on the strength side of training, which I know benefits me when running.
Julien instantly understood my requirements and developed a programme that concentrated on building leg strength while not ignoring my core and upper body. I was initially unsure of his methodology, as we moved fairly swiftly from one exercise to another (he doesn't do downtime!), but after a couple of weeks soon saw the benefit of this.
He understood I didn't want to 'bulk up' but stay relatively lean, while also improving my flexibility. After the first 2 months I signed up for a further 4 weeks and saw an improvement in my running form. He's a joy to train with and very personable
Highly recommended.

Laurent Miller
London
It has been very rewarding training together with Julien Bertherat, mainly because of his understanding of my specific desire to stay lean and tone up.
And his very positive attitude on life just makes you push your boundaries.
A great experience. I recommend!

Ben Edmonds
Milliner
As a regular gym goer. I felt as though I had hit a plateau in my training. I had seen Julien training other people in my gym and I felt that maybe I needed a little guidance so I got in touch with him and never looked back.
Within three months I had noticed a change in my body shape. I felt more confident in the gym and found a personal trainer that I could call a friend. I would highly recommend Julien to anyone wishing to take their training to the next level.

Denise McDonnell
London
As someone who was new to training and not knowing where to start I was nervous to pick the right Personal Trainer. Julien is an excellent trainer; enthusiastic, knowledgable, patient and supportive. He also gives you help and encouragement to move from one level of fitness to another. It's fun and relaxing and you learn something new at every session.
I highly recommend him.

Neil Feinson
London
Julien is an enthusiastic and attentive trainer who makes sure I achieve my goals.

Stuart Hodgkinson
Client Director, Advertising
I have trained with Julien for some time now. He is quite unlike other trainers I have worked with; very patient, gets to know his clients very well and knows how to get the most out of them. He does push you and is no pushover, but not a bully either.
For someone who is not as fit as I should be, Julien is very skilled at creating a programme that I can achieve, thus boosting my confidence to do more. He is also very knowledgeable about technique and nutrition and diet. Plus I really enjoy what we do and have fun whilst getting fitter all the time.

Adam Clifford
Yoga Instructor & poet
Julien is a fantastic trainer.
Certainly no meat head here! As he comes from a sports background he knows that weight training is not only about suitable size, looking hot and increasing self esteem - results of which he can produce. It's also about being able to hit your potential daily from the spring board of his holistic gym workouts!
I could not recommend Julien enough!

Rabah Aliouane
Musical Director, Paris
During these last two years Julien knew how to make me improve.
This isthanks to his complete training and instructions, which have been clear and his corrections have been very useful.
He just knew how to push me to overtake my own limits.
His energy and his personality were very useful to make the working session more pleasant.

Panos Mastis
Actor
What's good about Julien's approach is that it feels like he's working out with you (as opposed to working you out) according to your ability, need and current level of energy and enthusiasm.

David Marques
Yoga Teacher
Julien is a brilliant trainer who can sign basic sign language.
He is able to communicate to me how to get myself more fit and healthier.
If I didn't have someone like him, I wouldn't be able to achieve what I wanted.
With Julien I feel more confident.

Rupert Tyler
London
Owing to the sedentary nature of my occupation, I sought expert advice from Julien Bertherat whose enthusiasm, knowledge, patience, professionalism, as well as friendly character, have made me more motivated and determined than ever before to improve and maintain my fitness and wellbeing.

John Carlson
Banker
Julien is a hugely energetic and motivating trainer who pushes his clients hard, as he should. His sessions are varied and he always introduces new and interesting exercises.
Thoroughly recommended.

Joyce Didonato
Opera Singer
As an opera singer and stage performer, my body happens to be my instrument. After suffering several injuries to my ankles, I lost quite a lot of confidence in my ability to balance and train strongly.
Working with Julien has restored this confidence and helped me find not only a physical strength, but an inner one as well. This is the key to his training: working to develop your well being from the inside, as well as from the outside.
Julien's ability to adapt and improvise to maximise the workout on any given day is a huge bonus: I never feel as if I'm simply going through the motions.
Everything has a purpose and therefore I can see and feel the results in a very short period of time. I cannot recommend Julien highly enough.

Phil Rumbelow
Former Chief Executive,
Jubilee Hall Trust
Julien has trained me on a number of occasions with the aim of getting me fitter and stronger for my 10k running races.
He is an inspirational and inventive trainer who showed me a number of new techniques and encouraged me to always to push myself. As a result, I achieved a personal best time last year.
I would thoroughly recommend him to anyone seeking to improve their fitness levels.

Chrissan Moldrich
Creative Designer
My experience of Julien can be described as incredible. I first met him at the Jubilee Hall Gym, where I went to exercise. When he realised I was deaf Julien shows great interest in helping me and also learning British Sign Language so he could help other deaf people with their training.
I have known Julien for about two-years now and in that time I have helped him to learn basic BSL and his skills are excellent. He has trained me to exercise properly, whilst learning better BSL from me. I am very proud to recommend Julien as a professional fitness trainer and friend and wish him every success in the future.

Paul Dyer
London
Julien has been my trainer for three years and I'm now in the best shape of my life. He trains you hard (otherwise what's the point) and is considerate of your ability and well being. Julien will explain how to do an exercise and why you are doing it.
He is also a nice bloke!

Ian Kelly

I have been training with Julien for many months now. He has been so helpful with my weight training and fitness. He has given me so much encouragement and an effective plan to reach my goals.
Julien is a great motivator and has worked around my schedule too, which is always a bonus.
Highly recommended.

David Hodges

I have been training with Julien for just over a year and can honestly say that during that time he has inspired me.
I have never been keen on the gym, but Julien has been very encouraging and my weekly workouts are something I look forward to.

Julien is a great Personal Trainer who has helped me with an effective training programme, and one which I can continue with moving forward, wherever I am.
I recommend him to anyone who wants to work on their fitness or to improve their physique!

Cliff Jackson
Chartered Accountant
Julien was the perfect trainer. I wanted to be challenged after working out for twenty two years and being in a rut for the past few.
We did a lot of different exercises and changed my mind set about now to work out effectively.
He was always fun and great to be around, but also professional at the very same time. A great mood uplifter and a genuine guru.

Manjari Prasher
London
Julien regularly trains my husband and I at our home with a limited set of equipment. He does a great job of taking us through a one hour session together, even though we have different needs and abilities.
We have been working with personal trainers for a number of years and it is clear to us that Julien is well informed and can adapt to a range of styles. He has not only improved our fitness level, but has also given us the tools to carry on our training programme when we travel with or without equipment.
There is no doubt that we feel stronger, fitter and more motivated to keep up our fitness programme, thanks to his guidance, support and training style, which is well structured and complete. He is friendly and professional at all times and very easy to get along with.

Asad Farookhi
London
Training with Julien is nothing short of awesome and intense (in a good way). Julien is astute when it comes to the mechanics of the body and I've learnt so much about myself and my approach to training in a short space of time.
The best thing about Julien is his charisma and his friendly face each time we train!
