• 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.

  • 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!

  • 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.

  • 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!

    Laurent Miller


  • 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.

    Ben Edmonds


  • 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.

    Denise McDonnell


  • Julien is an enthusiastic and attentive trainer who makes sure I achieve my goals.

    Neil Feinson


  • 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.

  • 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!

    Adam Clifford

    Yoga Instructor & poet

  • 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.

    Rabah Aliouane

    Director, The Lion King

  • 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.

    Panos Mastis


  • 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.

    David Marques

    Yoga Teacher

  • 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.

    Rupert Tyler


  • 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.

    Joyce Didonato

    Opera Singer

  • 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.

    John Carlson


  • 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.

  • 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.

  • 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!

    Paul Dyer


  • 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.

    Ian Kelly

  • 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.

    David Hodges

    Property Developer

  • 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!

    Max Coles


  • 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.

    Cliff Jackson

  • 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.

    Danny McManus

    Income Audit Controller

  • 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.

    Manjari Prasher


  • 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!

    Asad Farookhi


  • 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.

    Highly recommended.
