Our staff at Covent Garden

Warren Greaves

Wellbeing Personal Trainer

How can I help you improve your health?

I primarily help men to transform their body through reducing body fat, building strength and improving their general health without having to go on restrictive “pop culture” diets or give up on enjoying life. I do this through a purpose built program (The Modern Superman Method) which consists of a 6 Step System to guide your transformation in Body, Mind, Health and Performance.

If you'd like support in building a stronger and healthier body to live in, a resilient mind to navigate the daily ups and downs of life and look, feel and move better whilst doing it, then email me to book a consultation.

What my Clients say:

“I first started training with Warren because I wanted to lose weight to feel better about myself. After achieving some weight loss and feeling better in my clothes we started focusing on being stronger and I fell in love with how it made me feel. My mindset totally changed and I felt that it helped me after stressful days at work and being a better partner at home.”

Pavlos Kouros

Wellbeing Personal Trainer

How can I help you improve your health?

Over the 10 years of my training career I have had the opportunity to work with experienced coaches and like-minded athletes from different disciplines such as Powerlifting, Bodybuilding, Weightlifting, Strongman and American Football. Through my journey in fitness, I have gained the knowledge to help improve people’s lives.

Paying attention to people and asking the right questions to reveal their true motivations is my passion and favourite part of the job.

After acquiring your true motivation, I will put together a well-rounded plan tailored to your individual needs and goals.

Together we will focus on progression and tangible goal setting so that you can truly measure your progress with me, regardless if your goal is fat loss, muscle gain or strength gain.

Joshua Stanley

Personal Trainer

How can I help you improve your health?

I am a Level 4 Strength & Conditioning Coach with a passion for sports. I have a football, combat sports and track and field background, but love to get stuck into almost any sport I can.

My role as a coach is to guide people through sustainable practices that foster better lifestyle choices to encourage the shift towards health, strength & longevity. I believe here at Nuffield that health, fitness and wellbeing are all individual aspects on the road to longevity. For most people, getting the balance right or finding where to start can be confusing and daunting.

On your fitness journey I will be there to support and push your progress in the direction of greatness through my adaptive personal programming & coaching focus on individual strengths and weaknesses.

Whether you are completely new to the gym/sports, have some experience but would like more guidance, or are an experienced athlete needing something extra to get to that next level. I'm here to help.

"I was new to personal training when I met Gabriela. I’d always thought that wasn’t something for me. I was completely wrong. Her training skills are fantastic, focus on form, build the core first; but her faith, attitude and drive made all the difference. Going to the gym is not necessarily fun, but she showed me how to make it work.” - Luciana
