Utilising his experience as a Decathlete and having worked with world leads in Nutrition and Athletics, Arj uses his own scientific model to provide clear guidance based on the latest research.

His vast knowledge means he is regularly asked to feature on national TV & radio, in print and online, which complements his belief that everyone should have access to elite level coaching tips.
