If there's one surprisingly reliable phenomena, it's that "strength" coaches will use terminology they do not understand to justify training methodologies which are ineffective at best.
I remember having to memorize all of this in A&P:
Your cellular ATP stores are used up in approx. 2 seconds, direct phosphorylation uses up Creatine Kinase/Phoshpokinase in about 15 seconds, Glycolysis takes over for about 2 minutes with Lactic Acid as a waste product, then it's straight aerobic respiration.
I couldn't for the life of me understand the distinction they were trying to make between glycolytic and anaerobic. Bro-science. That is the same stage, when glycolysis is creating ATP sans oxygen (outside your mitochondria). At least according to every Biology class I've ever taken.
