About our Mayfair gym

Our Ultimate Performance Mayfair gym stands apart from anything you have experienced before. Our world-class trainers and world-class facilities are just the beginning – we are so much more than a gym.

Since we opened our doors in 2011, we have built a culture of excellence here that breeds success with trainers and clients alike.  Time is money in London, so everything we do is designed to maximise your efficiency, your results and your return on investment.

Based in the heart of W1, within walking distance of Green Park, Marble Arch and Hyde Park Corner underground stations and accessible from Paddington, Victoria and Euston Stations, this is the place ‘where the excuses stop and the results begin’.

Our model

Unlike any gym you have experienced before, we do not offer memberships at Ultimate Performance Mayfair – we are a private personal training-only gym. 

Radically different from any personal trainers you have ever worked with before, our goal is not to retain you as a client for as long as possible – our singular focus is delivering you ‘maximum results in minimum time’. 

This unique model means that over the set time you work with us, we will help you achieve the absolute maximum results possible and give you a measurable return on the investment that your time and money deserve.

Our trainers

Our personal training team at our Ultimate Performance Mayfair gym is forged from the elite of the elite across the globe. We remain the best because we hire the best – only 1 in every 100 applicants makes the cut for a career with us.

The results-driven approach we have developed runs contrary to 99.9% of the personal training industry – our trainers’ success is measured and incentivised solely on the quality of their results and the value they deliver to the client – not on the number of sales they make.

Our dedicated personal trainers are your partner every step of the way, inside and outside the gym, guiding, supporting and educating to help you accomplish your goals.

Ultimate Performance Mayfair gym, located off Park Lane, is private and by appointment only, so you never have to queue for equipment, you are guaranteed privacy, and you can feel free and unfettered to train hard and achieve your goals.

Our methodology

Our personal training methods have been refined over the past decade with tens of thousands of clients to ensure the maximum efficiency and effectiveness of training to achieve the best results possible.  

We understand that every client is unique. So, every one of our personal training programmes is unique too – tailored to each individual client’s goals, needs and abilities to ensure we deliver maximum results and return on investment.  

Our methods and results are not based on the quick-fix mentality of the wider fitness industry. We pride ourselves on giving you the tools and real-world information you need to maintain optimal and sustainable health for life.  

Our results

We take your results personally. Everything we do, inside and outside the gym, is focused on giving you the best outcomes possible. In fact, the average transformation at Ultimate Performance Mayfair gym requires just 2.7 hours per week of gym time to achieve the kind of results we are renowned for.  

We leave no stone unturned from helping you with sleep strategies and stress management, to smart supplementation and nutrition, and bespoke training and diet plans constantly tweaked to elicit the best possible results.  

We understand that ‘results’ are more than just skin deep. Our scientific approach to body transformation means we track and measure every metric possible – from body fat and blood pressure to sleep and mood – so you can see quantifiable improvements before your eyes.  

Take a look at some of the life-changing transformations achieved by our clients across the globe.

Maximum results, minimum time

We live and die by our results. No personal training business on the planet can demonstrate the depth and consistency of transformations with thousands of clients that we can.  Such is the exceptional standard of our results that people often don’t believe they are possible.   

Promises are easy to make, but for anyone who is prepared to work hard and follow our guidance to the letter, then these life-changing transformation results can be yours. Here are just some of the incredible results achieved by our clients at our Ultimate Performance London Mayfair gym.
