Danny LennonAll Articles, Blog Posts, Combat Sport Articles, Nutrition Articles Comments

I recently received an email from someone who had purchased the Sigma Weight Cutting System for MMA & Boxing, asking why I had advised athletes stop caffeine consumption in the final 7-10 days before competition.

Danny LennonAll Articles, Blog Posts, Combat Sport Articles Comments

Supplementation. This could be a 4-part series in itself. However, I’ll skip on some details to get to: which supplements actually work which don’t and which are actually worth investing in.
