About Roan

Roan started his journey into human performance through competing in mixed martial arts. After conducting some tough weight cuts Roan knew that there must be a more scientific way to cut weight and maximise his performance in competition. 

This led to Roan becoming increasingly more interested in maximising human performance through nutrition and strength and conditioning protocols. Roan then began studying a bachelor of science degree in strength and conditioning and graduated with a first class honours in 2022, and went on to complete a Master’s degree and graduated in 2024. 

Over the course of his studies he has completed internships at elite organisations including: 

Ospreys Rugby

Roan then started coaching strength and conditioning to athletes and generalists forming Crock Performance, so far he has worked with athletes competing in Cage Warriors, Bellator, Professional Fighters League (PFL), Ares FC and the 2022 Commonwealth Games.

Home: FAQ

I had spinal and neurosurgery many years ago which prevented me from doing any strenuous exercise, due to this, I found my weight spiralling to the point where it was affecting my health. 

On the first of January 2021, I made the decision to change my lifestyle, I discussed my situation with Roan, and set my goals for forthcoming months to lose weight and improve my health and well-being. Due to my physical difficulties exercise was not possible.

After a consultation with Roan, I enrolled in a nutrition coaching programme, which would enable me to lose weight without any exercise. The programme involved calorie tracking and education of my food choices, whilst still enjoying my favourite foods and without feeling hungry.

ln 4 months I achieved a weight loss of 28lbs and for the past 2 months I have successfully maintained this loss. Due to this weight loss, my golfing performance has increased, my balance and swing has improved and my distance has increased.

Roan was a great help throughout the process, an excellent mentor. constantly on hand to answer any queries that I had, and providing easy to understand guidance. If there’s anybody out there who finds themselves in a similar situation as myself, Roan can and will be able to help you achieve what you may think is impossible.
