"I have been having Personal Training with Juan since March this year.  His training sessions are absolutely brilliant.  I have noticed a complete change in my body shape and feel fitter and stronger.  He pushes me to my absolute limit, but of course in a safe way.  If it wasn’t for him being there I wouldn’t do half as much as I do in his training sessions.  He is also a wonderful guy and fun to train with too. I know of other Personal Trainers and I can honestly say that he is most definitely the very best.  He loves his work and is totally dedicated to what he does.  This comes through when he trains his clients.   You can feel and see his enthusiasm for fitness which in turn makes you want to work even harder yourself." Jennifer 40 y/o - St Albans

"Following an initial trial session and consultation with Juan, I have now been training with him for 8 weeks.My goal is to lose weight, tone up and ultimately reduce my hip to waist ratio. With an individual nutrition plan and exercise programme created for me, I have in a relatively short time dropped a bra cup size and seen a reduction in my hip to waist ratio. The training sessions are fun and incorporate a variety of exercises which include cardiovasucular and core work. The exercises can be challenging, but Juan is very encouraging and always makes sure that you are doing everything correctly.At the end of each session I always feel a sense of achievement, and I know that with Juan's expertise and guidance, I will achieve my goal." Janette 50 y/o - St Albans – Cook

"For the first time in many, many years of doing my own thing, I was persuaded to book a series of personal training sessions with Juan. I have enjoyed each session and am amazed at the progress I’ve made, in a relatively short time.  My own personal target and focus was to improve my upper body and core strength. This is being achieved together with a real difference being made to my shoulders, general posture and body alignment." Maureen 64 y/o - St Albans - Golf player

" am a rower and I hired Juan to strengthen my core as this is critical in rowing effectively. After 12 sessions with Juan, I could noticeably feel the difference when race training and I have not looked back since. My posture and power in the boat have improved significantly and this probably wouldn't have happened so fast if I hadn't hired Juan. Juan is an expert who really knows what he talking about from experience, added to which he is a really great guy." Emma 40 y/o - Hemmel Hampstead – Rower

"I have really enjoyed my training with Juan. I don't normally like going to the gym much but Juan had made the sessions fun and with a lot of variety which has kept it interesting.  Juan is great at tailoring sessions to my requirements, so we had a completely different regime when I was training for the three peaks challenge as we do now I'm looking for more general all round fitness.  He was even able to give me a routine to do on holiday that could be done without any weights or machines.  Results have been impressive - much better than if I had been training alone, nothing is ever too much trouble for Juan,  and he is a lovely chap who is a pleasure to spend time with." Aaron 33 y/o St Albans - Project Manager

"When I first started with Juan 3 months ago I couldn't run or lift weights. Now I am able to do all the exercises he plans for our sessions. Juan has motivated me to push past my perceived limits to get results. I have incredible energy, my balance and flexibility have improved immensely and I've got great new muscles. Juan has not only helped with my fitness but he has educated me on how to eat the right foods at the right times. If you are serious about changing your life for the better, Juan will lead you every step of the way. "Lisa 34 y/o - St Albans - Global news programme Producer

"Having stored my favorite jeans for over 4 years, in the hope one day I may fit into them, after two months of working with Juan I'm happy to say the now fit with room to spare! No session has been the same, you never know what you will get, except results. Juan has provided not only exercise advice, but equally as important nutritional advice, which if you follow you get the results. I am now the slimmest and fittest I have been in over 5 years, during that time I have completed two Iron-Man triathlons so that just shows the results I have achieved working with Juan." Barry 50 y/o St Albans – Financial Director

“I've been training with Juan weekly for about 3 months.  Previously my main exercise was running combined with occasional visits to the gym.  Whilst my fitness level was okay, I lacked tone and wasn't confident when using the equipment. My goals are to build up my muscle tone and balance my fitness.  Juan places a strong emphasis on posture and correct technique, which has improved my confidence and ability when I'm training by myself.  Over the last 3 months I've lost weight, my wife has noticed a significant improvement in my body shape and I'm able to train harder. Juan is friendly and I find the sessions enjoyable.  He incorporates a wide range of exercises and through a good awareness of what I'm able to achieve motivates me to achieve more than I could by myself.”  Adam 35 y/o – St Albans - Lead Application Developer

“Under Juan's expert guidance I've made good progress towards my health and fitness goals. It is not just the expert training and nutritional advice that I like about Juan, but it is also the way he motivates and encourages you to push yourself. Juan's training sessions are always enjoyable, varied and satisfying and you always feel that you are making progress. Choosing Juan as my personal trainer is one of the best decisions I've ever made and a can fully recommend him.” Mark 36 y/o – St Albans - Researcher
