Our experienced


Oliver Berquez, Co-Founder

My passion is to see clients achieve results and I love helping people get there. Everybody’s goals, start point and journey is different and I believe with the right program and the right support anything is achievable.   

I was a professional footballer for 19 years winning 5 league titles and playing over 750 senior matches. What the years of playing sport taught me was you need to be dedicated, work extremely hard and most importantly be consistent.

I have been in the fitness industry over 15 years and in 2014 set up a community based health and fitness company called BlitzFitMe. In its 4 years of trading we have worked with thousands of clients and have numerous success stories. In 2017 the company franchised and is now operating in 3 counties, Essex, Suffolk and Buckinghamshire all with the same system and approach to help people no matter what the age, shape, size or capabilities.

I love seeing growth and whether it’s business or personal I have the same set of strong principles to get there. Plan, stay focussed and be unwavering in achieving them.

Everything I’ve achieved to date is the springboard to creating 4D Fit. I have always wanted to create a highly motivating and supportive environment which will enable people to live healthier, happier and stress free lives.

Daniel Reeve, Co-Founder

My greatest passion is helping others to achieve their health and fitness goals. I know that no single approach is the right one for every individual as everyone’s journey towards optimal health is different.

I believe in leading by example, I don’t accept feeling average and I centre my lifestyle around achieving optimum health and longevity. In order to inspire others to change, I constantly challenge myself and set goals.

My personal accomplishments include completing a deca-ironman, a gruelling 24mile channel swim, followed by a 1120mile cycle, finished with a 262mile run. I have cycled 5 l’etape du tours, ran 19 marathons, completed an ironman and hold titles in strongman. I am 2017’s 4th Strongest Natural U80kg in Great Britain and 2017’s 5th Strongest Natural U80kg in the World.

I have over 18 years’ experience working within the fitness industry. I have studied under and interned with some of the best strength and conditioning and wellness coaches in the world.

I have always wanted to create an environment which will enable, educate and empower my clients so that they can live healthier, happier lives and become the best version of themselves. 4D Fit will be that environment.

Alex Elvy, Head Coach

I use my passion for health and fitness, to encourage and inspire others to succeed.

My approach to inspiring others has grown over the years, as I have improved my knowledge of fitness and wellbeing.

My passion for health and fitness started from a young age having been involved in competitive sports.
I represented Kent at National events in both athletics and squash over a 2 year period before emigrating to Spain with my family.

My involvement in competitive sport during my younger years developed my disposition towards health and fitness.

Upon my return to the UK I completed my BTEC diploma in Sports.

I continued my education to specialise in personal training and nutritional therapy. I have since gained 6 valuable years of experience working with a variety of striving individuals, groups and sports teams.

I set myself high standards and am always looking to improve and enhance my knowledge, to ensure I continue and grow within this ever evolving industry.

I aim to inspire and educate each and every individual I coach. I have the aptitude to understand every person is different and am passionate about helping others achieve overall health and fitness, through training and the correct nourishment for sustained longevity.

I work with my clients to enable them to find their own approach to lasting health, happiness and confidence.

Tony Miller, 4D Rehab

Masters Degree Osteopathy
BSc Sports Therapy
Diploma Clinical Sport and Remedial Massage Therapy
Fellow of Applied Functional Science

The most rewarding part of my job is helping people who are in pain to reach their health and fitness goals, whether that’s someone who is just starting out on their fitness journey or the elite athlete.

I am able to achieve this through the use of manual therapy, movement therapy, manipulation of daily movement habits and advising on training programmes and lifestyle.

With 10 years experience and qualifications in the fields of Osteopathy, Sports Therapy and Personal Training, I am able to support my patients through the whole rehabilitation process. I have a specialist interest in the diagnosis and rehabilitation of lower back pain.

Having a long history in sports and exercise, I personally understand the frustration of not being able to compete, train or work due to injury.

My passion for helping others has lead me to continuously advance my skill set by travelling the world attending conferences and training courses by leading experts in the fields of biomechanics, manual therapy and low back pain.

Vicky Wood, Coach

As a parent you are always thinking about your children’s happiness and health, ensuring they eat well, have plenty of sleep, stay active and experience new things. So after having my children I really started thinking about my health and fitness, realising how important it was to look after me, in order to look after them.

I wanted to lead by example.

I only started going to the gym when my boys started pre-school, because I felt lost without them and thought this would fill the time!

Very quickly this “time filler” became something I loved. Not only becoming fitter and stronger physically but mentally too.

Once the boys went to University, and feeling truly lost, it really was time to follow my passion for fitness and health.

My primary interest is in resistance and strength training and love training others, helping them to understand the benefits of this type of training.

I am passionate about making a difference and want to help motivate and inspire others to lead the life they truly want and to feel awesome.

I believe everyone is capable of achieving their dreams, some of us just need a little help along the way. We are all different and everyone’s journey will be different but It’s never too late and every little change can make a difference.

I am dedicated to helping others to develop a positive mindset and lead a healthy lifestyle. Everyone deserves to feel amazing!

Rosie Vina, Sports Massage Therapist 
I feel a huge sense of self-fulfilment in knowing I can help people achieve their goals despite any barriers through injury.
My job as a massage therapist allows me to broaden other people’s knowledge on their own bodies and personal physical boundaries, helping people at any stage of their fitness journey safely perform to the best of their abilities.
I most enjoy being able to take individuals through exercise programmes as well as rehab programmes due to my qualifications and experience in personal training.
I was driven into the fitness industry through my own sporting background. I have played football for 15 years, including being part of Southampton Solent Universities ladies 1st team. I have coached and performed Kickboxing for 8 years, achieving my 2nd Dan black belt. From here I went on to study Fitness Management and Personal Training at Southampton Solent University.
My passion for sport and the fitness industry allows me to keep expanding my knowledge and provides me with an eagerness to keep learning and improving my skill set.
I aim to provide optimal care and advice to every client i see. Helping to educate and inspire each individual to achieve a positive future in their own fitness journey.
