Before And After Stories

Brady Selkirk

"The transformation that I have achieved training with Nash in four months was simply surreal! Nash has completely changed my training system, introduced me to the most effective training techniques and created personalised nutrition program for me that has helped me keep my size and get rid of all that unwanted fat that I couldn't lose for years. Training with Nash has completely changed my Life!" - Brady Selkirk

Cesare Pizzelli

"For years I was so ashamed of myself as I was obese, my self confidence was very low and because of that I didn't have any social life. Then I heard about Nash and just thought that he may help me. I started training with him and after he identified the best training and nutrition program for me, I started losing fat like never before! At the same time my muscles started growing and in 12 weeks I looked like I always imagined myself in my dreams. I'm still growing and looking forward to even better improvement. Training with Nash was the best thing I've ever done in my life!" - Cesare Pizzelli

Marcus Wilde

"I just wanted to thank Nash for my journey over the last year and our professional relationship together. He more than delivered on my goal in which I set out to do from my very first consultation with him. Stepping out on stage to compete under his coaching was one of the most thrilling and happiest personal moments of my life. He never once complained, never cancelled on me, he devoted his attention and focus to me at all times. Nash's professionalism, dedication and attention is second-to-none. I am forever grateful." - Marcus Wilde

Matt Young

"After spending years trying to reach maximum size and definition I just hit the wall and reached a plateaux I couldn't overcome. I was far away from my dream physique. Then, I came across Nash's website and gave him a call. He started training me, introduced me to training techniques and a diet that I never heard of before. After only 12 weeks my dream came true! I'm now bigger than ever and in the best shape of my life. Without meeting Nash I would never have achieved this level of development." - Matt Young

Jonathan Hughes

"I was looking for a personal trainer with the experience and enthusiasm to help me get the most from my training, someone with a track record of achievement that I could respect and learn from. Nash combines all these qualities with the utmost professionalism to help you get the most from your routine and diet. Training with Nash has been consistently demanding yet enjoyable, challenging yet rewarding. My progress says it all!" - Jonathan Hughes

Anastasia Ivanova

"Once I've decided to compete, choosing Nash as my prep coach was a straightforward decision! I got to know Nash in 2014 when I became his client and fell in love with bodybuilding. Nash made key adjustments to my diet and training to achieve the ideal stage condition for the Bikini category in the Miami Pro federation (amateur class) - all in the healthiest way without any drastic changes. Nash was a big inspiration and motivation for me, as he competed himself 46 (!) times and won many bodybuilding competitions. I put all my trust in his hands and it definitely paid off - I got 1st Place in Tall Bikini Category, named the Overall Bikini Winner and received a Pro card. Thank you so much Nash!!" - Anastasia Ivanova

Alex Vohmjanin

"I want to say BIG thanks to my coach Nash Jocic, for helping me prepare for my last competition. His guidance in training and constant adjustment in my diet in the last three months have changed my body beyond belief! I ended up in the best shape of my life  and as a result I won in my class at the Kent Classic 2016. I'm sure that under his guidance I can win the British Finals!" - Alex Vohmjanin

Ali Muhammad

"A massive thanks to Nash, who has helped get me in the shape of my life and even more win my first competition! Having worked with Nash I can say I am beyond impressed with the level of knowledge he possesses regarding nutrition, training and lifestyle. I actually nickname him the walking encyclopedia!" - Ali Muhammad

Panos Gikas

"Being a medical doctor myself I have been impressed by Nash's scientific approach to personal training. He has a broad knowledge and understanding of biomechanics, biochemistry, anatomy and musculoskeletal physiology and this together with his personal success in bodybuilding enable him to address all aspects of training from nutrition to somatic, physical and most importantly psychological support. Nash has helped me to dramatically change my body in only a few months of training and healthy eating. I wholeheartedly recommend him to anyone who is motivated and wants to experience a true professional at work!!" - Panos Gikas

James Demetris

"Although I have been training for 3 years, and I thought I was getting good results my body still didnt look as I wanted. Once I decided to compete I realised I would need help from someone very experienced. After much research I came to Nash's profile and made an instant decision. Training with him has been a complete eye opener. Nash had me in my best condition in just 6 weeks! He has also taught me a lot about nutrition and most advanced training techniques. I could definately not have achieved this size and condition without him." - James Demetris

Caroll Kerner

"Although I did enjoy running marathons I was not happy with the way I looked. On top of having no strength I had no muscles, therefore no shape to my body. Building muscles was what I needed to do in order to totally transform my physique. I had various PTs before but no one had the perfect recipe, expertise, experience, patience and vision other than Nash. Nash will give you all the tools and all the information that you need to succeed. He will see in you what you don't see in yourself. He can take you beyond your own limits. The rest is up to you! For me, training with Nash has been a total life changer." 

PS : Nash you mean the world to me! Thank you! - Caroll Kerner

Giusy Valvano

"Before training with Nash I had been working out by myself for about 15 years and I although I had a good knowledge of exercise and nutrition, I had never pushed myself to the next level. Deciding to train with Nash was the best decision I have ever made! He is absolutely the best personal trainer, with such an extensive knowledge of nutrition and training! In a very short period of 3 months not only I have gone from 63kg down to 54kg and thanks to his advice, but I have also managed to eliminate the stubborn fat that I had never been able to get rid of. He has motivated me so much that I have even decided to compete for the first time! I am really so excited now and cannot wait to start preparing under his supervision!" - Giusy Valvano

Nick Charalambous

"The moment I have decided to lose weight,I started looking for personal trainers in the area. I didn't realise that will take me long time to find the right one... There were so many trainers  to choose from, but none of them manage to convince me to pick him up. After spending a few weeks trying to find the right person for the job, I came to Nash's website I made an instant decision! I finally found someone who was not just taking the talk but also walking the walk! With such experience, expertise and track record, Nash was ticking all my boxes. We started training and results were simply phenomenal! He explained to me that discipline in diet and regular training are the key factors that will help me melt the extra fat away. I listened to every word he said, dieted strictly (not starving though, there was a lot of good food to eat) and  trained intensely under his close supervision and in 3 months I have lost  staggering 25 kg of fat!!! Not only that I manage to achieve my best shape ever, but at the same time I have become much stronger, more energetic, agile, and all my joint pains and aches have disappeared! I can whole heartedly recommend Nash as an expert who will manage to get you in the best possible shape!"- Nick Charalambous 

Terry Brown

"As I rapidly approached my half century it was time to reflect and decide on priorities. One of these was to start to take my gym training more seriously t"in order to look and feel better. Through a fortunate Google search I discovered Nash. His encyclopaedic knowledge of  weight training and nutrition has enabled me to make huge strides so that 2 years later I can honestly say that I feel stronger and fitter than ever. Nash is a true expert in his field and his training sessions are punctuated by pearls of philosophy thrown in as an added value bonus! Get with team Nash and you won't look back!" - Terry Brown

Rogan Doecke 

"It is not often that one meets somebody that inspires you to bring about a transformation in one's appearance and lifestyle. Rarer still at an age when most people are planning to take things easy. For me, such a person has been Nash Jocic. With a short space of time Nash has totally transformed my physique! His expertise and experience in fields of fitness, nutrition and life coaching provided me with a kind of a frame worker my future wellbeing. None of us have the ability to stop the biological clock - our life spans are to a large extent genetically pre-determined. But Nash has shown me that the quality of that life can be improved immensely - not only that, he has shown that it is possible not only to slow down much of the deterioration  associated with raging, but actually reverse it!" - Rogan Doecke 

Mo Naveed

"Although I have done few shows and competed for years, I still couldn't achieve my best. I knew that I need to develop more proportionate physique if I was to conquer the most prestigious competitions in the country. I was looking for an experienced  and highly knowledgable personal trainer who will be able to bring me on the next level. Even though I tried to work with some of them, results were not coming. At the same time, I observed Nash as the well known training coach and was astonished with the results he has achieved with his clients! Without exception all his clients were regularly improving, either they were beginners, intermediates or experience competitive bodybuilders! I spoke to Nash and explained to him what were my problems. I was simply impressed with his response; his answers were based on profound knowledge of anatomy and biomechanics, and I have not heard anything like that ever before! After the first session with Nash, my problematic muscles were sore like never before, and they remained sore for the whole week! I knew that I have finally trained them the right way. I'm very exited to continue with Nash and I'm also very confident that with his help I will finally manage to optimise my full potential!" - Mo Naveed

Lee Hayes


"Having qualified for the British championships final i knew i needed some help on my weaknesses.  So I went to Nash who I knew was one of the best bodybuilding coaches in the business. In 16 weeks preparation he turned me into a contender and i got 3rd place. So now I'm number 3 in Britain and after the results I got in that 16 weeks working with Nash I asked him to train me for the whole of the 2019 season, including the Arnold European Classic in Barcelona and the next British Championships. Although I am a good personal trainer and know a lot of things, Nash is on a different level. Simple!!!

Every session is like a learning course in bodybuilding and I am learning new things from him all the time. I love training with him, he has a great philosophy and in my opinion is quite simply the best in the game!!!" - Lee Hayes, 2018 UKBFF British No.3 in 70kg Bodybuilding 

Andrew Lobel


"As my problem was always putting on more size I've changed a few personal trainers in the past and tried different training systems and techniques. Unfortunately, not much changed in recent years. 10 months ago I came across Nash's website and was impressed by his knowledge and experience in the field, and especially with the results clearly shown by his changed clients. Nash has explained to me that the secret in building muscle tissue is not in the fancy and gimmicky training systems that unfortunately many unexperienced personal trainers advocate nowadays. He made it clear to me that if I want to change I will have to make lifestyle changes, meaning that I will have to be disciplined, committed and passionate about my workouts. Also, his advice on nutrition was second to none: as you can see from these photos my gains were clearly pure muscle growth without an ounce of extra body fat. I'm looking forward to my new progress and with Nash's guidance and expertise I'm 100% convinced that it will happen." - Andrew Lobel

"When I first got in touch with Nash it was because I had heard if you want to take gym and nutrition seriously you got to see this man!  I could not have been more correct! Every session with Nash is  like a 'lecture', which he warned me about before and I went ahead! Being a personal trainer, this mentoring from Nash has been a massive credit to my professional career as a coach in a field where I'm constantly learning new strategies and approaches. Nash instinctively knows how to get the best out of you, he does it naturally and has an extremely positive mentality! My personal  goals have been blown out of the water and training with Nash for 12 month I had completely transformed my body. Learning why and how we did it has been  massive wake up call for me and I'm so happy with what I have learned and continue to learn from Nash daily! If you are serious about getting into the best shape of your life, don't waist your time any longer, get the expertise that you need from a man that knows how and will change your life forever!" - Alex Rogers                  

Milos Jocic


"Not only did Nash introduce me to the gym, he introduced me to a completely different world of self-discipline, ambition and results. His expansive knowledge on the topics of anatomy, physiology and nutrition has allowed me make adjustments to my diet and training with full confidence. His expertise and legendary status in the world of bodybuilding serves as an inspiration to me and many others, and he continues his legacy by sharing his knowledge and changing the lives of many others immensely . his belief in me and his positive mentality has pushed my body and my attitude to improve exponentially. Simply the best!!" - Milos Jocic

Marco Vettorello


"I can simply say that Nash has changed my life! And that is not a overstatement! The reason I keep training with him is that I feel better, happier and never short of energy. I am Always in a good mood and more focused on the things I do. On top of that, I look better than ever too! When I check my abs in the morning I remind myself myself of what I have achieved and I never eat the wrong food again. When you achieve such results, you will never look back! I'm changed 100%. Look at me!" - Marco Vettorello

"I started my own business at 18 specialising in Apple computer support. After 15 years of hard work I found myself weighing 112 kg, overworked, stressed, unmotivated, depressed and fiercely overweight. This is not where I wanted to be at the age of 33  with my youth disappearing fast. Future was bleak! On the 1sr October 2015 I had to make a change... I started a new chapter in my lifeby joining the gym. Fast forward 7 years and I simply cannot be happier. In september 2021 I embarked on a new chalange when I met Nash Jocic. I was unhappy with my own progress and needed to bring in the big guns to take my training to the next level. Nash completely transformed my training, change my diet, while giving completely new stracture and purpose to my training. The results achieved in such a short time were above and beyond my expectations! With Nash's focus being always on a good form based on the essential principles of biomechanics, I have gained lean muscle mass, lowered body fat, increased strength and endurance but, above all, my previous aches/pains/injuries have simply disappeared! For me, the future is bright as we embark on getting in shape for my first Classic Physique competition later in 2022. It has been a fantastic ride and I can't  wait to see the results the future has in store dor me! Thank you Nash!" - Daniel Barrimor
