In Part 1 of this series, we thoroughly examined the truth about energy systems, their classification, specifics of each energy system, correct terminology used, and most importantly, how each energy system is interconnected and contributes to one another for energy provisions.

One of the more confusing aspects that continues to purvey is the role of fuel use during training, and even during recovery, and how intensity has large implications for these energy systems.

Many are discussing and even advocating basic programming ideas based on these systems without ever really thinking and knowing about how they work. This article will help set the record straight and examine the truth about energy systems.
