“I couldn’t believe the change within only 1 month training!!! I finaly found the place with all the support from my coach Kat. Day by day I saw rapid results in losing weight which was really hard for me until now. My coach gave me the motivation to push beyond my limits. This has been a complete life- style change for me and I really feel more confident in myself. So amazing!!! Now I feel much better than before, more energetic, my clothes fit better and it’s only half- way. Thank you so much, Kat, for making me feel better than ever! I feel so blessed, I have met one of the most beautiful, strong, kind, motivated and devoted person. I would highly recommend this program to all!

“Thank you for everything that you have done for us since the first day we met. You helped us a lot during this period, we learned a lot of new exercises, how to do them with a good form and also you helped us a lot on our nutrition. Even during this period of lockdown we are still motivated to reach our goal, and we'll do everything needed to achieve it! Thank you, coaches for the continuous support that you gave us every day!”

“When I did started my journey with Kat and Julien, I was personally not sure if I would be able to reach where I am today. Now when I look back, I am so overwhelmed and thankful that I met you both. You guys are a blessing in disguise for me. And I truly mean it from the bottom of my heart. My training was not only about losing weight, but rather loving what you're doing. And all that thanks to Kat. I've learned with my coaches that exercises and losing weight can be done without all these big fancy gym machines. Even with my knee issues, am grateful that they didn't feel like I shouldn't be doing any exercises instead Julien did encourage me to a great extent and am thankfully for the help, support and physio sessions and the personal attention I've received with both of my great coaches!”

Thanks you for everything, you are THE BEST! It's as a pleasure to talk and work with you! My experience was great and amazing. As a coach Kat motivated me to push my limits. It was 13 intensive classes. I push my body to be stronger each day. I learn how to eat better. I changed my life drastically. She helped me to trust myself and be more confident. She believed in me! Kat is not just a coach- she's a friend!”

“Kat is someone, who looks after us like a Mama Bear and is extremely committed about helping us to get in shape - at times even more than ourselves!! She goes really beyond what a coach would do: keeping us upbeat and positive, even when we are down, whether it is sports related or anything else, be it family or heart matters. The classes are always different- with new exercises or rhythms imposed, keeping them fresh and interesting. What I also admire is her ability to think on spot and adapt the training based on my energy level of that day! Kat is always able to connect with people, irrespective of their age, life experiences, personalities. That's a rare quality. She gives a 2nd, 3rd, 4th chance to anyone, who shows that he/she is a fighter. For me, you are more than just a coach – you are a friend!”

Thank you K&J! I am from the Corporate world with a hectic lifestyle. I never had time to focus on what I eat and exercises never seemed to find a slot in my busy schedule. Coaches helped me to understand the importance of a heathy diet and lifestyle. My Priorities suddenly changed! It wasn’t easy to change years of bad habits, but hearing the encouraging words from Julien saying “common, you can do it!” boosted me. I never thought I could sweat so much during the training – felt as if my body was crying – but my reward was the excitement of seeing my usually consistent weight of 60+ kgs being reduced!!! Memorable Experience of having a personal coach!

“After having my first child I experienced a lot of pain and loss of muscles. I wanted to get fit again and healthy. I had a weight loss goal and Ekaterina helped me every step of the way. Ekaterina is such a supportive trainer, she is always there for her 'fighters!' She kept me on track by sending me supportive messages and following my meal plan and correcting my bad eating habits. She always found a way to make time for me! She goes far above and beyond for her 'fighters'. Both coaches are very professional and knowledgeable. If you want to push yourself with great people it's definitely the place to be! Thanks to both Kat and Julien for the great work! (-13kg is the proud result of hard work and the time you both provided to me ) thanks a lot!!!”

“It was an exceptional and awesome experience! I have learnt exercises that I'd never imagined before which can be performed with simple accessories or your own body weight. Before we started to train, I was suffering from the pain in my right hand and NOW it’s GONE. Your guidance pertaining Food intake was crucial as well for me as I did not eat the right food and at the right time. Thank you both for your guidance, good advices and patience. It was a great pleasure to encounter so nice and so friendly people like you. May God always bless you in this wonderful job that you are doing!”
