Hahahaha, and where is this coming from? Do you need me to break down pathways for you again? Think about it, why is fatkid doing less volume than ever, yet doing lots of metcon and GC, while his maxes go up at the same time. Oxidation in the blood. I know what lactic acid is. I can get it from hiking for 15 miles, doesn't mean it was anaerobic. They may be brief, or it may be a 21 rep set, regardless, the set, and energy expendicture does not end as soon as you put the weight down. or do you just all of a sudden breath easier and not feel fatigued lol. That's not just lactic acid, that is pain threshold, VO2 max, and numerous other variables. If you know so much about this, post up some numbers man, the proof is in the pudding.
