Data-led, elite personal training to deliver measurable results

Our clients are supported at every step of their fitness journey by taking advantage of various apps that allow them to stay on track and see tangible changes.

We use the Everfit app to monitor everything from more than 50 body metrics and performance in the gym to bespoke training programs. This gives us complete accountability, which pushes you forward and helps you to maintain your fitness levels long term. For nutrition, we use Cronometer, an app that gives both you and your personal trainer a deeper insight into your health data with simple and detailed journaling of key nutrients, as well as your calorie intake and macros.

Achieve results faster with private fitness coaching

There’s nothing worse than a generic fitness and nutrition plan that is not only difficult to follow with your demanding schedule, but that doesn’t get you the results you crave in a reasonable timeframe. With a private personal trainer in London at your side every step of the way, you will find a companion who has as much focus and dedication to you achieving your goals as you do, and won’t let you quit until you reach your milestones.

We monitor strength development and muscular endurance over the course of weeks and months. This provides us with an excellent idea of every client’s stimulus-to-fatigue ratio as well as their load management, improving range of motion, and the developing structural alignment of their figure and form, so we can continually revise and tailor sessions.

Luna
CTO

I've worked with Sha from Muscles Mastery for just over a year now multiple times a week. He has helped me get stronger following a large complex trauma and tailored his work to accommodate the challenges involved and adaptations. We set a goal to get stronger so that management of the lifelong effects is much easier. When I started with Sha, I didn't really know what to expect but I didn't quite expect the level of enthusiasm and it's really motivated me to push through recovery. Sha uses a lot of tracking for training to send reminders and track diet, etc and while it is a pain for myself, it does seem to work, and I do see results. I wasn't actually expecting to end up a lot fitter, but it has helped me pace my energy a lot better too, which for me wasn't a goal at first as I hadn't realised it could be worked on! My work can be quite demanding due to scheduling, and I've been fortunate that Sha has been able to offer sessions very close to me, and he has been very flexible with scheduling. I aim for 3 sessions a week personally, but I know sessions sometimes need adaptations for health reasons so he is able to manage this. As a side effect of my training, I have ended up a lot more toned, which, while not being a direct goal, is very much a welcome one too, so I cannot complain with their expertise in this field. I have recommended Muscle Mastery and specifically Sha to others and will be continuing to do so!

Sha is such a nice and kind guy. When it comes to training, he is a great partner who is pushing your limit. I still know what I learned from him, techniques. He helped me lose about 10kg, and I went from a person who is afraid to be in the gym to a guy who is going to the gym because I felt super comfortable. All I can say is that he is a great PT; for me, he was 5 🌟 +! Thank you, Sha!

Sha hails from a world-renowned PT gym brand (no intro needed), so you can gauge from this background alone his level of expertise and knowledge, embodying the gold standard of PT training. I switched to Sha from a short stint with another PT, and the difference is night & day. My performance and physique have massively improved since training with Sha some 8 months ago, and I have come in leaps and bounds. I feel that Sha truly listens to the goals you wish to achieve and designs a highly customised programme to help you reach them within a rapid timescale (unlike other cookie-cutter programmes), whilst adapting to your own pace and ability, ensuring you continue to progressively build and/or hone what has been achieved for further gains. Sha is a distinguished PT; patient, encouraging, and pushes you to really progress in the most supportive and attentive way. His training style is based on positive reinforcement, which works perfectly for me, as a female. PT training or attending the gym in general can be a very daunting experience, but with Sha, he dispels all of these stereotypes and truly puts you at ease. His methodology and the transformation he delivers will both empower you and boost your confidence on the gym floor and outside of it. Sha brings so much energy and passion to each session that you just want to do your best in each one, both for yourself and for him. Finally, flexibility is a major plus, especially for a super busy professional like myself; you are able to chop and change at relatively short notice without forfeits, and Sha is super accommodating to my busy schedule. All in all, if you are looking for a body transformation with ultimate flexibility or feel stuck in a rut with your current PT and/or progress, then Sha is definitely your guy. Trust me, you will not look back!

My training experience with Sha has been nothing short of amazing! I have been training with him for about one year. My main objectives when I started were to lose weight and gain strength after letting myself go for a few years, and Sha has helped me with great results: I have lost weight, improved my muscle mass and general fitness, and I'm super happy about it. Sha has been very helpful all along the way, with particular care for my dietary requirements: he helped me craft the perfect meal plan, although I am vegetarian. I have been suffering from tennis elbow for a long time now, but Sha was very smart in crafting a program that allowed me to get results without jeopardising my recovery in synergy with my physio sessions. He's also dedicated to his clients' wellbeing, scheduling periodic sessions of stretching and de-load. Finally, Sha is great to work with: funny, motivating, chatty when required, very reliable (he never missed or arrived late to a training session) and flexible. Truly a 5-star experience!

Director of Engineering

I started my journey with Sha about 2 years ago. I was honestly sceptical about training on the gym floor because it was something I had never done before and thought it would have been boring. I started because of a friend's recommendation. I initially booked 3 sessions to evaluate before making any binding commitment. By the end of the second session with Sha, I was already looking forward to the next one. The week after, I subscribed for a monthly plan. Since then, I feel much stronger, and my weight has decreased steadily together with the percentage of fat while the percentage of muscle has increased. In just 5 months, I increased the amount of weight I can lift, and my body got closer to the target shape I've in mind. I've enjoyed every session with Sha, and he is constantly providing insightful information, helping me to improve and keep the momentum.
