"I have been a builder for 20+ years and I have suffered with a back ache for most of that time. However a year ago I started having a weekly sports massage with Jen. I feel so much better! I do not ache half as much and I feel 10 years younger! I only wish I had started this 20 years ago."

Steve West, Barnet, Hertfordshire

"I have trained with Briony & Jen and I can whole heartedly recommend them both. I originally trained with Briony prior to the birth of her daughter. When Briony took her maternity period I continued my training with Jen. They have both taught me so much and my whole view of exercise has changed dramatically in the past two years. I absolutely love my training sessions and hate it if ever I have to miss one."

Michelle Stokes, Welwyn Garden City, Hertfordshire

"I started training with Briony 5 years ago when I was preparing for my wedding. I wanted the perfect wedding and I also wanted the perfect body for my big day! I trained so hard and I would simply have given up if it wasn’t for Briony. She kept me going right to the end. I must say I did have the perfect wedding and the perfect body! Now I have a little one and Briony is back helping me lose the baby weight. Initially I only contacted Evolution purely to get in shape for the wedding. Here I am 5 years later still training – I just can’t give it up!!! Thank you so much Briony x"

Sarah Abrams, Hertford, Hertfordshire

"We have absolutely no hesitation in providing a testimonial for Evolution. We have trained with Briony and Jen and we even went to David & Briony’s wedding reception. They are all very genuine, thoughtful and professional. You might say we are an older couple whom have let things go a bit wobbly over the years – however we are now trimmer, fitter and much healthier than we ever have been. The sessions are very enjoyable but hard at the same time and we would highly recommend you give it a try."

Roger & Kathy, Whetstone, London

"I have been training with Evolution for at least 5 years .I have trained with David and Briony and I was delighted with both of them and recommend them highly. For the last year I have trained with Jen once a week. She has helped me through a very tough time in my life ... Carrying on training during my illness has helped me to focus and it gave me some normality. I am sure that it helped me being much less fatigued during my chemotherapy. I really appreciate the fact that Jen has been able to adapt my sessions to the ups and down of my energy levels and to the aches and pains after my operation. She has been very supportive and very kind. I am very grateful for this. I recommend her highly too."

Betty Miller, Hertfordshire

"I have trained with David for 7 years and still look forward to my sessions each week. He manages to keep the sessions varied and exciting, I never know what to expect. I have had type 1 diabetes since the age of 4 so keeping fit is paramount to my well-being, David understands this and has helped me to develop excellent motivation and fabulous fitness levels.

Couldn't live without my personal training, it makes my week!"

Kate Ward, Barnet, Hertfordshire

"David has been training me once a week for the last six years. I now train around three to four times a week on my own and I am much more aware of what I eat due to his encouragement. I have always found him to be concerned about any injuries before starting a session. The other thing that I find impressive is his reliability and punctuality."

Valerie Lenson, Hertfordshire

"I started training with David over 6 years ago. During that time I have had a one hour session weekly. In general I train 3-4 times a week including the hour with David. Over the years my fitness has improved dramatically as has my upper body shape. I have lost weight around my waist and thighs and am now the smallest waist size I have been since my late 20’s (over 35 years ago!)

I have had the occasional session with Briony too. They are reliable, friendly and very very good at what they do whilst being caring and very aware of overall health issues. I am fairly driven and motivated individual but have found that the motivation and help I get from Evolution has been key to my overall health and awareness."

Mitchel Lenson, Hertfordshire

"I have been training with Evolution for around four years. I train once every week but on occasion I may have an extra session. I enjoy the session very much as David is very professional and really cares about my progress. David is fun and interesting to talk to and we do have a laugh.

My fitness has improved greatly and I have learned routines that help me keep my body in order. I would thoroughly recommend Evolution as they are professional, knowledgeable and really nice people."

Michael Geduld, Hertfordshire

"I have been training once a week with Evolution for 3 years. I decided to contact them because I didn’t enjoy going to the gym and I was never quite sure if I was using the equipment properly. I train with David but I have also trained with Briony and they are as knowledgeable and professional as each other. Just before I started training with David I had completed the 5k Cancer Research Race for Life. I would never have believed that I could complete a sprint triathlon and half marathon but I have achieved both these goals in the last 2 years.

I feel fitter, healthier and training with David has become part of my weekly routine. I really enjoy the training sessions. I would recommend Evolution training so if you’re reading this, do something positive and contact them. It could be the start of a healthier, fitter lifestyle."

Nicky Morley, Radlett, Hertfordshire

"I always felt that personal trainers were a bit of a luxury but it soon became physically evident after working with David at Evolution that it was really making a big difference in a relatively short space of time. I have been training now with David at Evolution for over three years and have been impressed with the variety and motivation that he has brought to our sessions.

My fitness levels have improved beyond recognition and with David’s support and advice I have managed to maintain a healthy weight and body shape and have never felt better! I am now a firm Personal Trainer advocate and cannot recommend Evolution highly enough!"

Marc Plant, Bricket Wood, Hertfordshire

"I first met David in October 2008 after having surgery on my back when I wanted to get fit again but didn't want to risk damaging myself further due to lack of knowledge. I then introduced him to my husband who has since introduced both David and Briony to two of our friends.

Every session that we do is different which stops boredom setting in and David is always happy to prepare extra programmes for me to do between our training sessions or when I go on holiday to make sure that all my workouts are effective and cover all the muscle groups. His advice when we were setting up our gym was invaluable and he and Briony even took time out on their day off to take delivery and put our weight bench together. I would recommend Evolution without hesitation."

"I am an ex-professional rugby player and started training with David 2 months ago. I have not played rugby for a couple of years now. The training I do with David is fantastic and I love getting that burn again. My abs are coming back and I feel so energised. It’s a great buzz!!!"

Peter Brooke, Buntingford, Hertfordshire

"I had a triple heart by pass four years ago and I now train with Briony. It’s great for me as I know I will get a hard work out but a safe one. Briony’s knowledge is superb and I have complete confidence in her. I would highly recommend Evolution."

Rodney Thomas, Barnet, Hertfordshire

"I have been with Evolution for 2 years now and have achieved the goals we have set. The sessions are great as they are varied each time and this prevents boredom in the gym!! The best part of the arrangement is the home visits at weekends which makes life easier! I am motivated each time we meet.. although sometimes I need to be reined in!! Thanks for all your support... a great way to train and people should definitely try it!!"

Anon, Hertfordshire

"I have been training with David for approximately 7 years, initially meeting him for some help post car accident. I train once per week with him and I always feel stimulated and energised following our sessions and value this time. David has seen me through many of life’s ailments and offered enthusiasm and stability when my fitness has been impaired through illness etc. I feel fitter, I have toned up , I use my training to manage my stress level and achieve a healthy mind/body balance.

David is a great personal trainer, his knowledge and experience have helped me greatly and he is always keen to help devise appropriate new programmes and techniques to help challenge my fitness. I find David encouraging, kind, firm but fair and value him greatly as my trainer and friend. I feel privileged to be able to name him as my trainer and would heartily recommend."

"I am happy to recommend Evolution. Jen is both very professional and most personable. As an ageing Head of a school, I have found weekly visits from Jen to be remedial and restorative. My back, my energy levels and my general health have improved significantly. Jen is punctual, reliable and trustworthy."

Irina Tyk, Potters Bar, Hertfordshire
