I recently heard that periodization is dead. For those who are unfamiliar with the term, it can be defined as the division of training & competition into various phases throughout the calendar year (this is of course a simplified definition - articles, books etc have been written on the topic but for our purposes, that’s all you need to know for the moment).
Before we tackle the statement from above, let me provide the background story. There was a once a time when athletes - primarily those competing in the Olympics - only had to (truly) peak once every 4 years.
