Byron is a gentleman. We had some very jolly family sessions that managed to mix the skills, needs and interests of 8 year olds and 50 year olds with lots of laughs and inspirational chat mixed up wit a solid training schedule.

Byron is a unique and exceptional personal trainer. We've been working together for 2 years and over that time Byron has been instrumental in improving my boxing skills, my mobility and fitness levels. But more than that, Byron is just great company and a truly inspirational character.

Byron is a fantastic trainer who engages his clients to the fullest. Not only are his classes challenging, making sure you build a sweat, but his positive character and encouraging demeanour keeps a smile on your face. Byron is great at creating a routine that works on a variety of body parts and is always willing to personalise it for your goals. I would recommend him without a doubt! I love training with him and I’m sure anyone else will feel the same.

“I am loving working out with Byron. He has taught me the fundamentals of boxing, improved my fitness training technique and given me motivation to keep going. He makes every session challenging and fun, and I keep coming back for more! Would recommend to anyone looking for a one to one fitness trainer.”
Georgina Harley
I had the pleasure of Byron being my trainer in several group boxing / HIIT classes and he is one of the best trainers I have had. His enthusiasm and encouragement towards each and every person in the classes is outstanding and it makes such a difference having someone help and encourage you every step of the way. He has great knowledge and advice when it comes to all exercise, and in group classes he takes time with each individual to correct them if they are not quite doing something right. He's an all round lovely guy and I cannot recommend him highly enough!

I have tried many PT’s throughout my fitness journey and I can honestly say Byron stands out as a favourite. His communication while boxing makes it super easy to keep up, which lets me focus on technique. He easily builds workouts based on my “worry spots” and is always making it fun. Without a doubt, I always leave a session with Byron feeling super positive knowing I’ve worked really hard- it’s a real highlight to my week!! Thanks Byron
Laura Tisch
Byron is the most inspirational trainer - his energy and positive attitude are always motivating and he really knows how to push me beyond my limits! I've been fit and always trained regularly but since starting with Byron, I've discovered a whole new level of boxing and training during our sessions - challenging me on technique, strength while always making it fun! The bonus of training with Byron, is that not only do you get a killer workout but you get to take all the skills and inspiration with you for all your training sessions !
Claire Abeille

Byron is a fantastic trainer. I’d been out of boxing for many years and was anxious to returning as I knew my fitness levels were low. Byron understood this immediately and worked a regime around this, pushing me and motivating me to keep going beyond that which I thought capable. He’s a brilliant motivator and a wonderful person, he cares for everyone of his clients and has a deep personal relationship with them all. Top trainer, even better human.

Byron trains both my boys, aged 14 and 16. Not only has he improved their physical performance (boxing, football and general fitness) but he has also given them more confidence and a better understanding of the wider benefits of regular training. The boys always look forward to seeing Byron, he works them hard and really pushes them out of their comfort zone. He even continues to check in with them when they are away at school, offering friendly support and advice. A trainer in a million who really looks after both the physical and mental aspects of wellbeing.

Johnny Goodwin

“Training with Byron is always a pleasure. He competes at a high level in his sport of boxing and trains in a variety of combat sports. This means he has a wide base of know-how and experience to help you and make it fun if you’re just starting training again or looking to take it up a level. During intense sessions he is able to motivate me and still keep an eye out for subtle techniques and correct where needed which is ideal. Training with Byron is a great choice for a beginner in the gym all the way through to someone who competes athletically.”

I have been with Byron for about 6 months. He’s the best. He’s become more of just a PT to me. He’s become a friend and mentor, he’s helped me and has put hours in to help me improve as a character. My boxing ability has improved and continues to do so. My fitness has also improved so much and all of these improvements I have him to thank for. I still train with Byron and intend on doing so forever. As his common aim is - he’s the highlight of my day - Thanks for everything.

People often use the words ‘personal trainer’ without thinking about them, but that’s the best way I can describe Byron. He makes each session feel unique, he structures the training around you and how you’re feeling, and most importantly he’s an amazing guy. He shifted my mentality from exercise being a chore to something that has become the highlight of my week. For anyone wondering about whether it’s worth it, I can make that choice for you. Yes. Absolutely. I can promise you you won’t regret it.

"I'm not a huge fan of gyms or working out - but I've enjoyed every training session with Byron. He's really good at knowing when to push and when to just have fun. We mix up the training depending on how I feel and what's going on in my life. Sometimes we focus on skills and fitness and sometimes I bring my four year old son along and we mess around."

Byron is a hugely positive motivator who not only reshaped my body and posture but also helped installing new habits to improve other aspects of my daily routine.

Byron is a professional pt and he made me fall in love with fitness. I loved all the sessions I had with him at Marylebone gym. His workouts are challenging and never boring. If you wanna have a sweaty and efficient workout with a professional personal trainer Byron is all you need. So grateful to have met him!
Nicole Astori
Byron has been my boxing coach for around 4 months now. As well as being a top-quality coach he is also a genuinely nice person! He comes with 100% commitment and passion to each session pushing me to levels way above what I thought was capable. My boxing ability, fitness and confidence has drastically improved in a short amount of time. Each exercise, drill and activity are fully explained. Byron is a top-quality coach for all levels whether you are starting out or a seasoned athlete.
Jag Jhaj
Byron is a charismatic and genuinely kind coach. Through my experiences being trained by him, I have learnt that he understands exactly why you want to be trained and will get you there. Byron will push you to the limit even when you don’t think you will be able to overcome the exercise or something greater, he’ll push you to be there. He requires your all and if you give it, he’s easily the best coach/trainer in the UK.

I have taken private boxing lessons with Byron for a few months now. He is incredibly encouraging, a great boxing teacher and joy to be around! Both my fitness and boxing skills have improved a lot since starting sessions with Byron. I am excited to continue working with him!
Elise Kalinovich

I have done a number of private 1 on 1 boxing sessions with Byron and could not recommend him more as a trainer! Although I was slightly nervous before my first session, Byron made me feel at ease, relaxed and was very clear with his instructions. If you are looking for a boxing coach in West London Byron is great!

Byron is an amazing motivator My friend and I joined one of his full body fitness classes just before lockdown and I have never wanted to go back to a fitness class fast enough! Unfortunately due to Covid I was only able to join one but he made it fun while also working us hard. I would highly recommend as he makes it enjoyable that you can’t wait to go back!

Byron is an excellent trainer. He puts his soul into developing the person and keeping them motivated. Byron trains my whole family ages ranging from 45 -9 and he tailors his approach accordingly, to get the best out of everyone. Would 100% recommend Byron.
Tam G

When I first met Byron, I had been offered a free test session and was not looking forward to it. I thought that it would be awkward training with someone that I had never met before, and that I would not enjoy myself. However, to my surprise, my opinion was rapidly changed after that day, and I have never regretted turning up to any lessons, and have enjoyed every single one thoroughly. Byron is a great coach, but even more so an awesome guy, and I would 100% recommend him to anyone wanting a personal trainer. He works me hard, but at the same time he motivates me a lot and after every session he leaves a smile on my face.

Byron is an amazing PT. He is so fun and knows how to push you without over doing it. He keeps me motivated and makes me enjoy working out and trying new things whilst working hard and staying focussed. His enthusiasm and energy are infectious. I cannot say enough nice things about Byron. He is personable, professional and extremely knowledgeable. I absolutely love my sessions with him. He caters to your personal needs has tons of information and makes you feel comfortable no matter what level you are on. He challenges you appropriately, makes working out fun and generally makes you want to work out.
Roxana

Byron is one of my most favourite coaches, that I've ever trained with. He alway pushes me over the limits to make me realize how strong I can be, and how stubborn I am towards my goals. He will always explain, show me how to exercise safely and will listen and encourage if I think I can't make it. He makes sure that training is consistent and effective. I have reached my desired results faster than I thought, become happier and more confident. It is always a pleasure to train together with Byron! If you want to make a change, he is the best person to be there and support you till you will reach that set goal!

I have been training with Byron for nearly 1 year and thanks to him I have found my favourite sport. I knew nothing of boxing when we first started, I have learnt a lot and can see a massive improvement in my ability and fitness. He is an amazing coach, always positive and motivating, open to help you at anytime. He is very perceptive and knows how to keep your energy levels up! Each and every very session he always pushes you to the best of your ability. Sandra Huerta
