I have been training with UP now for over two years which may seem like a long time to train for a body transformation but this training is so much more than that. UP has become an essential part of my healthcare approach to mitigate the risk of developing all those chronic age related conditions which hold you back in your 60s. I have never felt stronger and more able to live the active life I have always chosen without injury or medication. I continue to gain strength and fitness, to manage a diet which feeds my body without changing my dress size and to feel confident in every step up and down the most challenging of hikes.
A great life choice and worth the investment of time and money thanks to the expertise and encouragement of the great team at UP St Paul’s managed by Lewis.

Two years at UP

Serious privacy concerns and poor value…

Serious privacy concerns and poor value for moneyI would not recommend this gym for women or based on my experience.I signed up for 16 sessions and ultimately left after 12 sessions at London City Gym. My personal trainer was excellent, so my concerns are not about the trainer, but about the wider business and customer experience.1. Male trainer entering the women’s changing room without permissionThe most upsetting part of my experience. On one occasion, after my session, I was alone and undressed in the women’s changing room. While staff were holding a team meeting nearby, a male trainer knocked and then put his head around the corner before I had time to respond, to ask me to turn down my podcast.I found this deeply inappropriate and distressing. Regardless of the reason, a male member of staff should not enter or look into a women’s changing room while a client may be undressed. It showed a serious lack of judgment, respect for privacy and customers.To their credit, the manager and regional manager followed up quickly and refunded my remaining sessions. However, they refused to refund my £350 membership fee, citing their terms and conditions, emphasizing that they had already given me money back for unused sessions and this was in fact against their policy. Given the seriousness of the incident, I found that disappointing, and it reinforced my impression that commercial considerations were prioritised over customer well-being abnd safety..2. Sales-driven culture over customer experienceIt felt like the business prioritised sales far more than customer care. After sessions, there were team meetings held outside the changing rooms focused on company sales performance. I appreciate that every business needs to make money, but hearing repeated sales discussions in that setting gave the impression that revenue mattered more than the client experience.I raised this concern with my trainers, who passed them on to management, but nothing appeared to change. That made me feel that customer feedback was not being taken seriously. 3. “World’s leading personal trainers” claim An exaggerated marketing statement rather than something clearly supported. If a gym makes a claim like this, I would expect to see evidence of exceptional qualifications, recognised industry standing, or some form of external credibility behind it. Without that, it creates mistrust rather than confidence.4. Cost and value for money The cost worked out at around £165 per PT session, which I do not believe represented good value. A significant amount of session time was also spent on weigh-ins and measurements. In the first session, around half of the time was taken up with this, and then every two weeks a further 30 minutes of session time was used for repeat measurements. I understand the importance of tracking progress, but at this price point I do not feel that paid PT time should be reduced so heavily for assessment and admin-style check-ins. If these are considered essential, they should either be built into longer sessions or provided separately.I would also have expected a higher standard of equipment for the price. There is technology available that can measure body composition and other metrics far more efficiently than doing it manually. If a business presents itself as having the world’s leading trainers, I would also expect it to provide them with the best tools and equipment.5. App not well suited to UK users The food tracking app did not seem properly adapted for the UK market, as it did not recognise UK supermarkets or restaurants. At this price point, I would expect better functionality and localisation it is available on other apps.Overall, while my trainer was very good, the wider culture, privacy concerns, poor response to feedback, and high cost meant the company experience did not feel professional or customer-focused.

Fantastic private training gym

Once you have trained at UP you really wouldn’t want to go to any other gym. My trainer is so professional and patient and motivates me to be the healthiest and strongest version of myself that I can be.

My time with UP has changed the course…

My time with UP has changed the course of my life. I started out 4 or so years ago aged 57 about 30kgs overweight. UP taught me how to eat properly, and then through weight training, gave me the strong defined shape I had always craved. The trainers are what make UP so special - absolutely dedicated to your success and extremely knowledgeable. As a result of my experience I wrote a book about mid life ‘rewiring’, changed career to food retail and invented a sugar free date ball, and am now writing a cookery book. I am in better shape now at 62 than I was at 42. UP is a genuinely life changing experience and worth every penny of investment.

My experience was amazing and a major upgrade to my workout regime.

My experience was amazing and a major upgrade to what I was already doing. I had been working out successful for 1,5 years when I started with my UP experience. My trainer Marcus really knew how to stretch my limits. In a way that everytime after a session I was proud of myself and I did things I didn’t know I could. I really want to inspire everyone to give yourself this experience. The only reason I am not giving it a 5 stars, is that I didn’t use the full offer with the nutritional plan and measurements after every session. A compensation by for example an extra session or anything else of that order would have made it ultimate!

Jay Stevenson sets standard!

Although I have, not so consistently lifted weights and trained in various sports… my biggest issue has been keeping to a strict diet!Enter Jay Stevenson from Ultimate Performance! Not only has he introduced me to a strict diet, but his precise training is something i’ve never encountered before. Whether it’s free weights or machines, Jay takes pride in making sure I do it in the correct way! I don’t lift as much as I know I can, but the technique taught by Jay is working my body in a completely different way. Quality over quantity is Jay’s method and although initially I wanted to lift more weight, over time I have realised the core t technique is the way forward!!! Will definitely recommend UP and Jay Stevenson.

Great Transformation

Embarked on a transformation journey with my trainer, Ivan, and the experience has not been short of life-changing. I learnt more about proper nutrition plan and proper workout routine, which I would strive to make a lifestyle in the long run!

Having Hashimo’s and being menopausal…

Having Hashimo’s and being menopausal…Having Hashimo’s and being menopausal has caused a significant weight gain and other health issues for me, which I have struggled with the past 7 years. I had tried various gyms, sports activities and diets. I would lose 2 to 5 kgs, but as soon as I stopped , the weight would pile back on. Feeling depressed and desperate I kep on searching online for a solution. One day I came across UP on FB. I was impressed by the reviews and results shared by clients. I made an appointmen. Inwas initially taken aback by the high cost, but I thought it must be worth it—and I decided to go for it.My first personal trainer, Marcus, was a young and enthusiastic man who pushed me physically beyond limits I never knew I had. I learned how to eat three proper meals a day and to walk at least 15,000 steps daily.My second personal trainer, Konstantinos, is a mature and precise individual who has taught me valuable training techniques and has been incredibly supportive when it comes to nutrition—especially in helping me experiment with ways to reduce inflammation.So far, I’ve lost nearly 11 kg. I still have a few more to go, but I’m confident I’ll reach my goal weight. I feel so much stronger, both mentally and physically, and the daily muscle pain I used to have is now almost nonexistent.I feel truly blessed to have come this far, thanks to the support of such an amazing team of trainers. I highly recommend this to anyone dealing with autoimmune disorder.Datum van ervaring: 31 juli 2025
