why do later what you can do now


Hi there, I’m Warren Johnston. Qualified Personal Trainer, Pilates Instructor & Life Coach.

Since becoming a personal trainer in 2012, I’ve realised my passion to be about helping others progress their personal development journeys. As a former South African national gymnast, I’ve learnt that mental preparation, motivation and discipline create the life you want. And that to get all of those things right, you'll need to enjoy yourself along the way.

Whether you're just starting out or looking for a new challenge, your well-being comes down to more than just showing up at the gym. It all starts with your mind-body-soul connection.

I can help you strengthen that connection, to unleash your power in every area of your life.




I have been incorporating Warren's calisthenics classes into my training for the past 8 months, and I have enjoyed the challenge and seeing the progress I've made during this time. Warren is an incredibly knowledgeable PT, and I appreciate the functional foundation of his training to help build a stronger body for life.

I was not physically active since early high school and had not done a stitch of exercise before meeting Warren. Going to the gym just didn’t work for me and so I decided to try out a personal trainer instead. I was amazed at my progress and the ability to at least try exercises and activities that I had never attempted before! Warren is excellent at always surprising you with what’s planned out for a session and trust me it will stretch your abilities and boundaries and push you to achieve more! Sessions never got boring and an hour would just fly by! I never ran at all and after a year of training, I managed to do my first 10km road race with ease and 100m sprints on numerous occasions.​

I am a 65-year-old client who worked with Warren on my joint mobility problem. I have osteoarthritis in my one shoulder, due to an injury 20 years ago. I had been to various physios for this, it just seemed to get worse. He very carefully assessed my shoulder and gave me a plan of how we could work to improve it. I was really impressed with his attention to detail in the rehab of my shoulder, he emphasized small movements that built strength without hurting me. He also did some fun things with me. I felt supported and motivated with him. We had some interesting chats about nutrition, stress and sleep to name a few topics. A real gem of a human being.​

I have had a complete body and mind overhaul, as well as a better understanding of nutrition whilst training with Warren. Most importantly he listens to your needs and targets and tailor-makes a programme for you; this is reviewed approximately every three months. He has a whole repertoire of exercises sourced from different forms of exercise. For example, yoga, pilates, stretching, martial arts, dance, and circus skills! Not only are you focused on the physical aspect during the session but you also gain an understanding of the benefits to the various parts of your body and how that will impact your daily life. Warren has a ‘glass half full’ attitude to life which encourages and challenges you to reflect on your values. Despite the apprehension of working with a personal trainer at the start Warren has kept me motivated to work at my best and he has become part of my life routine. I would highly recommend him for all ages and at any stage of their exercise programme.​

I’ve been working with Warren for over two years now, he’s given me great all-round training. We have seen increased fitness and strength and I have been very encouraged by the progress. He’s always been extremely flexible with my hectic work travel schedule and very creative in the way that we train be it at home, in the park, or even online during the lockdown! It’s always a session about body and soul and alongside this nutrition and diet advice.
