I thought about doing CHEK to but didn't. I have done a course called Metabolic Precision by Paul Cribb. The course is based on nutrient timing around when you train. The first part of the course is nutrition based and the second part is the practical part. It's a great program and it will increase your income.
He does these courses in melbourne over a weekend so it would mean you would probably have to spend a night hear but it's worth it.
He usually only runs them once a year.
