Billy Thornhill Fitness

Fantastic experience: Billy helped me get back on track with my training goals. He was very happy to tailor a program that suited my needs and taught me how to push harder and get the most out of sessions. Great coach and great guy to be around.

Fantastic experience: The most versatile, knowledgeable, professional and fun personal trainer you’ll ever meet!! Coming from a yoga background I’ve never considered myself a gym person but thanks to Billy I’m loving it!! I feel confident using the different machines and I’m seeing results in just three months, I feel stronger and fit but also motivated and determined to keep my journey and keep improving, but above all excited to keep training cause it’s fun every time with Billy and he pushes me enough to keep growing stronger. I decided to look for a PT cause I used to suffer from migraines weekly due to a car accident years back, bad postural habits, muscular tension and weakness, Billy guides me through each workout, exercise and movement and adapts the workout to my needs every time so I can get stronger without compromising my resistance and triggering the migraines and the result is simply amazing! I don’t have regular migraines anymore!!! I know how to perform my exercises thanks to Billy and migraines are now a rare episode in my life, I know consistency is key so strength training is now part of my life and I’m lucky to have THE BEST PT!! Billy Thornhill, so if you’re a beginner like me don’t hesitate to contact him and even better, if you’ve been on this journey for a while and want to jump to the next level then Billy is your man!

Fantastic experience: Great Trainer! Good vibes and solid results - Could not recommend Billy more!

Fantastic experience: I trained with Billy for several months, during which time he taught me proper technique and new exercises which helped me gain more confidence in the gym. He always showed up with high energy and motivation. Would highly recommend as a trainer!!

Fantastic experience: I recently started exercising and wasn’t sure if having a personal trainer would be worth it. But wow, Billy completely proved me wrong! He’s super knowledgeable, pushes me just the right amount, and makes every session engaging. I’ve already seen progress I never expected. Highly recommended :)

Fantastic experience: I’ve had a handful of PT’s over the years but Billy is hands down the best I’ve ever had. From the start, he’s made every session not just productive, but genuinely enjoyable. He knows what my limits are and does a great job of pushing me - even when I try to negotiate doing fewer reps. I cannot recommend Billy enough!

Fantastic experience: Billy is a legend. Have made so much progress in the gym and am always learning new exercises. He’s got a great sense of humour and is extremely knowledgeable about all things physical fitness, health and nutrition. He is even certified in Pilates and has helped me a lot with pain and recovery. 10/10 recommend to all!

Fantastic experience: Billy has been an excellent trainer. He has been able to adapt the exercises for my rehab and made them goal orientated and challenging. For someone who hated the gym, I have enjoyed the last 6 months training with Billy. Through his knowledge and motivation, I have finally returned to the sport I love. Thanks Billy!

Fantastic experience: I’ve trained with several trainers over the years but in the 6 months I’ve been training with Billy I’ve seen the most significant improvement in how I look and feel. He takes the time to understand your goals and what works to keep you motivated and focused. The only downside is the dad jokes at 6.45am!

Fantastic experience: Billy is a knowledgeable, supportive, and motivational PT, who designs great programs and will get the best out of you. I was paired with Billy through my gym, with the goals of losing weight and learning more about the gym its equipment. Billy has consistently designed engaging workouts that both challenge me and allow me to have fun exploring the gym and different exercises both in our sessions and on my own. Billy willingly shares his expertise and knowledge, answering any and all questions I have about diet and exercise. Perhaps Billy’s best quality is that he pushes me far beyond what I thought I was capable of, in a supportive and collaborative way.

Fantastic experience: Billy is an awesome trainer - He has great knowledge of all sorts of training styles / exercises which allows for each one of his sessions to have a little bit of variety whilst still consistently targeting his client’s goals. My training with Billy in explosivness/ strength has helped improve my athletic performance as well as general well-being.

Fantastic experience: I have been training with Billy since August 2023. After an accident last year I had seen a huge loss of strength, fitness and psychologically it has been very challenging. Now I’ve seen an improvement in my strength and feel empowered. I’m not someone who naturally enjoys exercise but find the sessions motivating with his support and agile approach to my workout plan so that nothing ever feels too hard. I 100% recommend :)

Fantastic experience: Billy’s the best! Very knowledgeable with the mechanics of working out. He is great at tailoring a program to suit specific needs. Highly recommend!

Fantastic experience: Highly recommend Billy to anyone who is looking for a PT. Incredibly supportive and works with me to achieve the goals I want to hit.

Fantastic experience: Never looked and felt better since having personal training with Billy. He made a conscious effort to tailor my workout plan around the type of workouts I enjoy, and as a result I feel motivated and disciplined, which I’ve typically lacked.

Fantastic experience: Billy is amazing! I 100% recommend. He is professional and super helpful in making sure you meet your goals in a realistic time frame

Fantastic experience: You couldn't ask for a more personable PT. Billy goes above and beyond, always churning out useful info on his profile and somehow manages to be available and responsive to my messages even when I really wouldn't expect it of him. I'm on a 12 week program with him at the minute, and the absolute thoroughness and variety within it for every single muscle group is brilliant, including core, warm up, cooldown, varients, tempos and active rest days. I also did a program with him a few years ago with little to no equipment and he still managed to put me through my paces and keep me improving my fitness If you're serious about training and have the commitment, I wouldn't hesitate to recommend mr baldy bald boy - you'll be seriously enjoying your training and getting solid gold advice and tips every step of the way. Hell, even if you're just looking for casual PT I'm sure he'd be just as good! Youll get your moneys worth in any sense of the word

Fantastic experience: Billy is super enthusiastic, down to earth and a wonderful fitness coach. I’d highly recommend him if you want to kick some serious fitness goals.

Fantastic experience: I had such a good experience with Billy working to my goals and accommodating injury. Such a lovely and professional, person, every session was really fun! He supported me through the week between sessions, sent me exercises and rehab resources for my injury. He is a good laugh too. I would recommend Billy to anyone!!!

Fantastic experience: Billy is a fantastic personal trainer and coach - he’s encouraging and pays attention to any improvements you can make on your form for you to get the best out of your workout without injury.

After several months, I am pleased with my progress and I am sure that with his continued training and encouragement, I will continue to achieve good results and reach my goals.

Fantastic experience: Billy is everything that you can wish for from your personal trainer! My husband and I needed to brush up on our lifting technique and mobility, we both needed support on slightly different things and Billy was fantastic at accommodating both of us at the same time. He is lovely to work with, super approachable, and excellent at what he does - five stars for sure!

Fantastic experience: Results guaranteed Best in West London (after me , lol). No matter what your goal is Billy will help you to achieve it! I am also personal trainer and I have decided to train with him as I was struggling to push myself above my comfort zone! Have achieved those hard weighted Pull ups and weighted Dips! PS: He is also great Fun&Crazy dancer. LoL. Not around West London just go online and get him to train you remotely!!! Thank you Billy for the push!

Fantastic experience: Great personal trainer, massive impact on the gym environment, massive juicy peach!

Fantastic experience: Recently completed an online 4 week strength training programme with Billy via his app. This made his service easy and accessible, he was always available to give feedback and advice through videos. The sessions were structured and varied very well which made them enjoyable but challenging! High recommend…

Fantastic experience: Billy is so friendly and makes exercising fun! He went through the extra effort of learning about my injury to help tailor the programme to my needs. Cannot thank or recommend him enough!!

Fantastic experience: I was lucky to have Billy as my first PT, he kept me motivated and on track when at times I found it difficult training around my busy work schedule. Billy is always positive, patient and a pleasure to work with. I felt like I was training along side one of my mates rather than a PT. I highly recommend Billy as your first or next PT. Nothing Less Than 5 Stars!!

Fantastic experience: Billy has been fantastic to work with the last month! I’ve been doing online training with him, doing a mixture of strength, cardio, stretch/yoga. He really listened to my goals and tailored a programme to suit that even though it’s online, he shares demo videos of exercises and he’s only a WhatsApp away. He’s super fast at replying and will usually send videos to show me to improve form. I’m signing up for another month with him and can only imagine will keep doing so. Cheers for everything, Billy!

Fantastic experience: I found Billy to be very friendly and approachable but also a good motivator. He prepared a well structured workout to help me meet my goals with plenty of variation to keep it interesting. He was recommended to me and now having worked with him I would happily recommend him too!
