In their own words
Hear from athletes I’ve supported through training, fight camps and everyday nutrition.
Confidence in nutrition. Support along the way.
Since working with Colin I’ve noticed significant improvements in both my training and performance and I’ve gained so much knowledge and confidence around nutrition. I also really appreciate how thorough he is with explaining everything and answering all my questions.

Let’s talk about your goalsThe best I’ve felt around my training even whilst cutting large amounts of weight during fight camps was with Colin’s help. Colin always answers any questions professionally and is full of knowledge.
He made fight camp a breeze. Whenever I had a question, he would take the time to give me a very thorough answer. You can tell how passionate he is about his field of work. I always recommend him to people, as I know how much of a difference he made for me.
Great, Colin helped a lot with cutting weight for boxing, whilst still having energy to train, was really helpful with planning meals which were all delicious.

Before you get in touch
No. Tell me about your sport, experience and goals. We can discuss whether my support is a good fit for your needs.
Combat sports are a central focus of my work, and I also support athletes across other sports. Get in touch and tell me what you’re working towards.
Yes. A one-off consultation lasts 30–60 minutes. Afterwards, I provide a first-draft nutrition plan built around your training demands, lifestyle, cooking time, opportunities and motivation. Ongoing coaching is available separately if you would like continued support.
If you’re based in Perth, we can meet online or in person. I work with international athletes online. We’ll arrange the format when discussing your enquiry.
I offer weekly check-ins and daily support through SENPRO, alongside practical nutrition guidance and adjustments as your training and needs change. All coaching messages are kept in the app, and I usually reply within 24 hours.
Once we begin working together, I’ll help you get set up. Your plan, recipes, food and training logs, habits, check-ins and messages are brought together in the app. We’ll agree what you need to track, so the information is useful to your coaching.
Send an enquiry with your sport, the support you are interested in and any competition date. I’ll discuss availability, fees and the appropriate next steps with you.
