Who do I work with?

From the top, it's worth saying that I don't work with everyone. If you apply to my online coaching and I feel like I am not the best person to help you with your goal, or, in the other direction, that you might not be someone I can work with, then I will let you know straight away.


People who are willing to put in the work will see the best results. If you think that paying for a coach means you will start losing weight or gaining muscle like never before, then you're not who I'm looking to work with. I will give you all of the tools and knowledge you need to succeed but you are directly responsible for putting everything into action. The work won't always be easy but the results you get from it will be worth it.

People who are determined to achieve their fitness goals. If achieving your health and fitness goals in the next couple of months is at least a nine out of 10 for you in terms of importance, then you're exactly who I'm looking for. If it's not that important to you, then please don't apply.

People who know they don't know everything. If you already think you have all of the answers, then I'm not the coach for you. You need to be in a place where you can accept help and advice. Your ability to achieve results you've never had before will be unlocked if you are open to implementing new strategies and are ready to learn and take action. If this sounds like you, please do apply!
