At PTX Fitness, we honestly love what we do. Seeing our clients getting leaner, fitter, healthier and happier is why we get out of bed in the morning.

So whether you are a busy professional looking to take back control of your health or just looking for the right way to become slimmer, stronger and fitter we promise we can help you.


I constantly use myself as a case study because like you, I don’t fit into a conventional box.

After forming Stephen Clarke Fitness in 2005 I've helped thousands of men and women transform their health and fitness. I've made plenty of mistakes along the way but learned from them and constantly evolved my coaching practice. That valuable experience and the results we create has led to co-creating a successful online business - The Kilted Coaches to take our knowledge worldwide as well as becoming a TV Presenter and weight loss expert for a national TV show.

This means early morning starts at 5am, sometimes having no time for lunch and nothing more than a 30 minute window to have a workout so I have to constantly develop eating strategies and exercise routines that will fit into any lifestyle. I’m living proof that busy lives doesn’t have to mean poor health and that fitness ‘rules’ and guidelines are meant to be bent and broken to mould around even the most unique of lifestyles.

In an unpredictable world YOU are your biggest asset. 

Although my background is in personal training my passion now sits in human optimisation and personal performance. When you upgrade yourself you’ll find all other areas of your life also improve dramatically including your health, wealth or relationships. 

This absolutely still includes effective training and clever nutrition but with more emphasis on personal psychology, energy optimisation and life coaching. 

Everyone — from entrepreneurs and business professionals to busy Mums and everyone in between— can experience more success, happiness and fulfilment in their lives with a few simple shifts in their daily habits and thought processes.

‘Surround Yourself with People who Inspire You’

Hi! I’m Sarah, mum of two wonderful boys aged 6 and 4 and I also happen to be Stephens wife! I’ve joined the team recently and I’m looking forward to working behind the scenes as well as working closely with the guys to bring You, our client, the very best Personal Training & Nutrition Coaching Experience. 

My interest in nutrition stems from my time working as a Makeup Artist, having worked with many different clients (particularly brides) and their different skin types. I found myself advising my clients on the best course of action to achieve smooth, glowing skin ~ the percent canvas for beautiful makeup. Of course my nutrition knowledge was pretty basic other than advising on increased hydration, eating water rich foods, proper skin care regime etc. However what I loved most was seeing the difference in my clients skin after just a few weeks of them incorporating these basic changes into their skincare routine. I saw how happy my clients were, they had a sparkle in their eye and their skin looked wonderful! 

I could see how much my clients took from our time working together, it led on to a real passion for helping people and I wanted to learn more about the effects that Nutrition has, not just for our skin but our whole Health & Well Being. 

As a Mum, it’s important to me that I fuel myself properly ~ I have a real interest in how nutrition affects our energy levels, and that of my kids. I know how I feel in myself when I’m really taking the time to be mindful of my nutrition choices that I feel great and my kids get the very best of me.  Through my Nutrition coaching at PTX, I want to help YOU set and accomplish goals in a way that is empowering and exciting, we will work together to achieve and maintain your ideal weight and increase your energy levels. You’ll feel great in your body, learn about new foods and how you can easily incorporate them in your daily life and improve your personal relationship with food and other areas of your life. I want You to feel empowered with your Nutrition journey and discover the confidence to create the life you want! 

“Have body confidence, be your own you and have fun with your training!”

After studying and working within sport for 8 years, I realised my passion for personal training at a later stage than most. I've always had a passion for health and fitness, studying sport science to degree level at university and sports coaching prior to that at college.. But never had the urge to be a personal trainer, So why?

With working alongside personal trainers in different local football clubs it was easy for me to see how rewarding the job was, I also received many different sessions from many different trainers, throughout this time my interest started to grow. As my knowledge became greater I then took the plunge into my personal training journey by becoming fully qualified myself and have never looked back!

Plus I get to wear a pair of trainers to work everyday! How cool is that?!

I realise effective training and having a “balanced diet” can be tricky at times, especially when you lack the knowledge and sometimes the motivation. This is where I can help you and most importantly we'll have fun doing so! With over 8 years of coaching experience I know the importance of tailoring my advice to each individual. Everyone has their own exercise and diet history so I adapt my advice to suit. Sometimes less is more, sometimes more is less and sometimes you have to forget all of that and just do some squats.

They say “if you enjoy your job you'll never work a day in your life”, I couldn't agree more with that and I am very fortunate to found something I love!

Nick's training philosophy -

“Fitness isn't about being better than someone else, it’s about being better than you used to be”


For almost five years I worked in a job which was not rewarding in the slightest, I worked from 4am to 12pm, went to Judo at night, ate, slept and repeated Monday to Friday. In 2017 the opportunity to complete my level 1 UKCC Judo coaching presented itself and looking for a challenge I enrolled.  It was during this course that my affinity for coaching became apparent and once completed I sought another means of furthering my personal development. In my quest for improvement I began training Brazilian Jiu Jitsu in April of the same year, given that it was completely new to me it was a humbling experience and served to elucidate how much there was still to learn- even after training and competing in Judo for 7 years!  It became increasingly obvious that I love learning and need to be challenged in order to evolve.

 It was for this reason that I decided to complete both my HNC and HND Fitness, Health and Exercise at Perth UHI and in the process attain:  Exercise to Music, Level 2 Gym Instructor, Group Cycle Instructor and my Level 3 Personal Trainer qualifications.  During this time, I have read voraciously and watched countless hours on the subject of strength and conditioning as well as sleep, nutrition and meditation. 

I truly love health and fitness and relish the opportunity to aid others in their journey to achieve goals they never thought possible. I want to make your experience as enjoyable as it is rewarding as well as educate you on the subject. I believe that no man or woman should forego the privilege that comes with improving both mind and body. 

John's favourite quote:

“No man has the right to be an amateur in the matter of physical training. It is a shame for a man to grow old without seeing the beauty and strength of which his body is capable.”


― Socrates

I started my fitness journey way back when TV was still black and white, well almost. I left school at 16 and went to work in the golf industry as an assistant professional, after realising I was not going to be the next big thing, I moved into health and fitness gaining a number of qualifications along the way. I picked up many valuable ideas and core concepts that I still hold close today. It was during my time in Perth that I first worked alongside Stephen Clarke, little did I know our paths would cross again some time later. I took everything I learnt and went back into the golf sector, this time as a marketing consultant for large US golf resorts. I now hope to use everything I have learnt throughout the years and put it all into practice for PTX, the journey continues……..
