Here's how it works
To transform your body and change your life, working out is not enough, you need a proven system.
The 12-Week Transformation Program focuses on mental reprogramming, flexibility, sustainability and enjoyability. 

Mental Reprogramming

Anyone can tell you that you need to go to the gym to transform your body although for how long are you are going to keep it consistent? In our program, we focus on teaching you how to be disciplined and how to rewire your brain and drop your old bad habits.


A great program needs to be flexible. What if you're travelling? What if a food is not available? What if your schedule suddenly change? With our program, we will teach you the principles of flexibility and how we can adjust it based on your lifestyle.


Everyone can follow a program, but very few can sustain it. In the 12-Week Transformation Program, you won't just transform your body, but you will also sustain your results using our proven process.


A great program needs to be enjoyable as well. We will teach you how you can eat the foods you love, at your times, no matter if it is a meal at your favourite restaurant or bar for a drink and still get amazing results.

"Xenios is the best personal trainer I ever had, I have been working with him since October 2016, and within a short period we managed to achieve big changes after following his advice and instructions."
"About a year ago Xenios "bullied" me 😂 into eating properly and exercising hard. This is where it took me. I was lucky to find someone like Xenios who is knowledgeable and persistent, who managed to sort out my diet and attitude towards workouts."
"Before joining Xenios program, I used to struggle with self-confidence and motivation. I wasn't happy with my appearance and wasn't happy with my personal life until I discovered Xenios. His program has helped me to lose over 20 pounds of fat and helped me discover who I am as a person. His guidance with nutrition and training was truly professional, giving me step by step instructions on what to eat and how to train. Thank you Xenios for all your help man!"
"Today, as I near age 29, I am just saying that I have lost over 30kg and I have gained my confidence back. Thank you Xenios for helping gain my confidence back!"
"Working with Xenios I have found my self to think and act beyond what I thought it's possible for me! Working with him and get the results you have to be committed to doing three things: show up, work hard, listen to what he is saying"
"I am not sure where to start and where to finish. I am just shocked by the results I managed to achieve over the past few months. All thanks to Xenios knowledge for making the impossible, possible!"
"I was depressed, unhealthy, not happy with the way I look until I met Xenios. His 12 Weeks Transformation Programme helped me discover who I am as a person. His programme is not just a body transformation but "mindset" transformation as well."
"Getting into this shape in 3 months is just unbelievable. I tried many personal trainers and programs before but with Xenios's coaching and mentoring I am now able to sustain the results and enjoy my lifestyle."
I initially started with CrossFit, and after trying it for many months, I realised that I wasn't progressing and I wasn't happy with the results. I decided to start personal training because I wanted to increase my core strength, performance and gain more muscle. I train for over a year with Xenios, and I learned a lot of new techniques that I didn't know about. As a busy person, I don't have time to eat meals, and I didn't know how to structure my diet in a way that fits my busy schedule. I started with a macro based high calories diet which I found very hard at the first week, although after the first week I realised how easy and sustainable it is to follow it with Xenios's methods. Overall I gained a lot of strength, increase my upper body size and most importantly fix my core issues.
Head Of X-Factor London
I wasn't happy and overly comfortable with the way I looked, I put a fair bit of weight, and I wanted to get rid of that. I knew that in order to get my happiness back and feel more comfortable with the way I look, I needed to transform my body and drop my old habits. I decided to start personal training and get in the best shape of my life. As a busy individual, working as an actor, my biggest challenge was preparing and eating meals. I realised that nutrition is a huge factor when it comes to achieving great results. Xenios has taught me techniques and strategies that are specifically designed to help busy people just like me. I managed to implement the diet successfully and got some fantastic results in only a few months. Eventually, I gained nearly 5kg of muscle mass, lost a lot of fat in just six months.
I had a severe event to attend, and I had only three months to get in the best shape of my life. I am coming from a background of horrible habits, and I decided to take the challenge and join Xenios's hyper-exclusive 12-week program to accomplish the required physique for my event. I had no idea that it is possible to get such amazing results in just 12 weeks because I had worked with personal trainers and I kindly know how the experience is... Well after joining Xenios's program I realised that his approach is way different than any program I ever tried before. Is not just about the exercises, or the nutrition but also the mindset aspect that made me understood that I came to the right person. After getting directions on how to make my diet more sustainable, and even by following a fully personalised programme designed precisely for my situation, I managed to get amazing results in just 12 weeks and met the physique requirements of my deadline.

I wanted to take my physique to the next level and learn advanced principles of nutrition and training as I was already training for five years without a personal trainer and try to do things on my own. I like to stay in shape because I want to look good in clothes, at the beach and most importantly because I value my health. As a real estate investor and a scientist, I work around 12 hours per day and my time is extremely limited so our challenge with Xenios was to find somehow a solution that will fit the perfect nutrition and training programme that will be according to my busy schedule. I tried many different methods before but by far what has worked best so far is what I learned from Xenios. I managed to successfully gain muscle mass, lose fat in just under 12 weeks. Now I have the proper knowledge, sustain the results and do it on my own. I would highly recommend Xenios to anyone who is looking to take their body to the next level.
Real Estate Investor
I started my fitness journey at 88kg and managed to get down to 70kg with Xenios's guidance. It is just unbelievable that I lost 18kgs so far as I tried many things before like intermittent fasting, the ketogenic diet, personal trainers, P90x and nothing lasted. I kept gaining the weight back until I started Xenios's approach. The fact that I can now sustain my results, enjoy my lifestyle and save the results going is what exactly I needed. I am now much stronger, much healthier and way more positive compared to what he was before. My advice for anyone who wants to start this is, If you don’t have a personalised nutrition plan that is exactly for you then all the training you do is just a waste of time. You also don’t need to spend 1-2 hours at the gym. 40-45 mins are enough.
Before I start working with Xenios, I was following free non-tailored programmes from the internet and getting advice from youtube. At the beginning, it worked although at some pointed I was overloaded with information and I didn't know what to follow as everyone was saying something different. I decided to join Xenios's program, and I realised how important it is to have professional guidance and a system designed for my individual needs. My biggest struggle was to find time to train and eat as I run multiple businesses. Working with Xenios's, I learned how to optimise my nutrition and workout programme in a way that fits my schedule. One of the things I liked about his system is the ability to eat the foods I love at the times that work best for my schedule. My advice for anyone is, If you put in the time and have everything clear for you, organise it then everything would be great.

Chef Service
For busy people who don't have time to cook
For super busy clients we provide a Chef Service!
As part of our premium personal training service, we understand how valuable your time is. Most of our clients are busy professionals or entrepreneurs with a very hectic schedule.

Our responsibility at Xenios Charalambous Fitness is to design for you highly personalised meal plans based on science which provide the precision, structure, and consistency to achieve your health and fitness goals.

We have solved this issue with a chef service dedicated only to our elite clients in central London. If you're a very busy person and you don't have time to cook, we are going to assign for you a personal chef that will do the grocery for you, cook and deliver the meals for you fresh every single day at your office or home. Our clients are saving at least 12 hours per week with our chef service.
This is how it works
Can you guarantee my results?
If you follow exactly everything that we will tell you to do, you log everything, you stay accountable, and you keep everything consistent daily then yes, is almost impossible not to see results unless you have any health issues which we will examine before the start of the program.
Where are you going to train me?
Xenios and his coaches are currently located at Urban Kings Gym as shown on google maps above. For clients who require an entirely private experience we have another private gym just 7 minutes walk from Kings Cross station, or we can travel to your private house gym.
Do I have to pay for a gym membership?
No. Everything is included in the program.
How often are we going to train per week?
The minimum number of times that we currently do with all our clients is 3x per week for a duration of 12 Weeks. We don't accept anyone to join for 1x or 2x per week as you won't see any noticeable results. At Xenios Charalambous Fitness we focus, deliver and promise you results.
Can you give me advice for a diet?
Yes, a personalised nutrition plan is also included with the program. You will be forced to follow it as is a MUST if you want to achieve some good results. We will even provide you with an 8-weeks course which teaches you the logic and fundamentals of a sustainable nutrition plan.
How do I book a session with you?
You will have your 3 standard reserved days and times on our timetable, and you will need to attend those days and times. In case you're busy with work or have some other unexpected appointments, you will need to inform Xenios or one of our coaches within 48 hours prior the scheduled session or 1 week in advance if you're traveling abroad.
How much each session cost?
At Xenios Charalambous Fitness we don't charge per session, either per hour. We run a 12-Week program and the price is fully personalised to each individual according to their needs. We will suggest you to watch our free demo and then book a free consultation to find out more how we can help you.
Do you offer trials?
Yes. If you are not sure or ready to commit for 12-Weeks we can sort out something personalised for you according to your situation. Book a free consultation call and we will sort it out for you.
I am traveling to London for a few days, and I want to work with you. Is it possible?
Yes, we will recommend you to book a free consultation call and we will quote you a price based on the days you want to get coached.
What if I don't live in London and still want you to coach me?
We will still recommend you to apply as we offer a service that Xenios flies to your country. If you still want to work with Xenios but you don't live in London then we will give you more information about the "Spartan Coaching" program. Book a free consultation call to find out more.
We are located just 1-min walk from Kings Cross Station
