Onur is one of the best trainers I’ve come across and I can’t recommend him enough! I started sports at a young age and managed to stay injury free until a ski accident as an adult resulted in a torn ACL. I was looking for a personal trainer that had extensive experience with athletes and who had a holistic approach to strength and conditioning now that I was a little older. Onur is more than qualified across various aspects of strength and conditioning training and his approach to training is how it should be: first do it well, then do it more! He has a kind and inclusive way of coaching, which has given me the self-confidence to keep pushing during our sessions. He makes sure to check-in on your nutrition, your sleep, and other lifestyle components to make sure he is applying a 360 approach to your training. Finally after 7 years of physiotherapy, Onur is the only person to have gotten my knee back to where it was, If not better, and in less than 6 months! I’m very grateful to Onur for everything. See you next week Onur! 💪💪💪

After having reached a plateau with my training and lacking any inspiration on what to do next I was introduced to Onur through my wife who was already working with him at the gym. We've now been lifting together for the last 4 months and I've been super impressed with what we've been able to achieve. Onur has an infectious enthusiasm that is incredibly motivating and with his direction and experience I've seen huge progress in both my strength and explosive power. I'd always struggled with my technique, was worried about getting injured, and also unsure about how to train to achieve my goals. It's been great to have someone with such extensive experience planning my sessions so I can just concentrate on working out. He's a great teacher, who's vast experience and knowledge shines through in every session, and knowing that he is watching all my training to ensure good form has given me the confidence to push my limits. Honestly I can't recommend his services enough to anyone looking for someone to help them with their training. 5 stars really isn't enough, should be at least 10. Thanks Onur!

I have struggled with my weight for years and have numerous times joined the gym and stopped due to not being motivated. I decided to give it one more try and contacted Onur for 1:1 session. At the first session we discussed my underlying health issues and my goals and what I want to achieve. He is super knowledgeable person, so we looked through all my blood tests to discuss how to tackle my weight the right way. 6 weeks on I am loving every single session and feel super motivated but what’s amazing is that my last blood tests showed that I have reversed one of my underlying health issues which I had struggled to control for 3 years. Onur makes the sessions fun, enjoyable and has a personal approach according to your needs. He uses Polar Band which monitors training progress by tracking relevant metrics and it helps to keep me going as I can see how much calories I burn at each session and at the end of the session he uses Theragun to help with stress and sore muscles. Since I’ve started, I’ve lost 12 kilos (2stones) and lost several cm from my waist but also feel much stronger physically. Even when I have days where I feel the goal is difficult to reach, he always spares a few minutes to sit and reassure me and remind me how far I have come. Besides my physical health, his sessions have really helped with my confidence, sleep, asthma and overall wellbeing. I 100% recommend Onur, he is a fantastic personal trainer and no matter whether you need sessions for weight loss, muscle strength or anything else – he is the best guy to go to in London!

I have had several personal training sessions with Onur and have found them to be high-energy, invigorating, and varied workouts. He is incredibly thoughtful, thorough and tailors each session to your personal goals. I am impressed with the changes to my physical appearance and personal strength in just a short space of time. Thank you Onur for your commitment and hard work. I would recommend 1K Pro Training wholeheartedly.

Onur is professional, knowledgeable and a dedicated trainer; his medical knowledge and knowledge of fitness is outstanding and he can achieve results, no matter who the client is. He takes a holistic view of all his clients and aims to improve their lifestyle and not just their fitness. I have gained more muscle mass and lost fat in such a short period of time and I am very grateful for Onur's services! Definitely would recommend! 10/10
