Justin is the man!! I have been training for 9 years now and thought I knew a fair bit about training and nutrition. I decided to take it to the next level by taking him on and it really put it into perspective how little I knew. Justin is an extremely knowledgeable coach and does it in a way where you take small steps to a much larger goal. He is very supportive and whilst changing your lifestyle can be extremely difficult, he has made it a seamless part of my daily routine. I have dropped body fat and even gained muscle mass, which was something I didn’t even know was possible for a natural like myself. Trust the process, you will be in extremely capable hands. Thank you for everything so far Justin, I look forward to seeing the progress continue!

Justin is dedicated to each individual tailor made to each individual, he will be accessible anytime of everyday. He can be talked to about any subject and offer the best advice and understand to your private situations. He has helped me outside of the gym and kept me on course. My day to day health has been so much better, more energy and awareness

I had the pleasure of working with Justin, who conducted tests on my VO2 max, lactate threshold, and resting metabolic rate. His attention to detail is truly unmatched—he left no stone unturned in his approach. I was genuinely impressed with the results and can’t wait to collaborate with him again in the future! Highly recommend his expertise!

Coming from someone with little knowledge of the RMR test initially, Justin took me through the whole process and set me up for success when it comes to my calorie intake. Also opened my eyes to info on blood sugars and ways to keep my energy high throughout the day with diet. Highly recommended.
