something ive noticed...thoughts?

My theory is it takes awhile for our body to start releasing sufficient glycogen to supply our fast twitch muscle fibers with energy.

Remember fast twitch muscles do not use oxygen, they use glycogen. Reactions using glycogen require anaerobic enzymes to produce power.

if this theory was true, we wouldn't be able to sprint, anaerobic work relies on glycogen immediately, the body doesn't wait or delay release of it (what if the 225 was the last set he did), it is meant to be used under conditions in which oxygen cannot fulfill our energy demands and takes place rapidly otherwise he wouldn't have any atp to lift at all

I experience the same thing, especially on leg movements. I think it has to do with where your head is at. During the warmup, you're probably not focusing to hard, you haven't pumped yourself out, and in general, there is no pressure to perform. Once you arrivate our your work set, all of these factors are reversed. The difference is particularly acute if you do a high intensity routine.

This explanation can also go some ways in explaining why form can feel a bit shaky.

for me it is mostly a mental thing and i think warrior said it well. i naturally focus more on my worksets because I have to. nobody pysches up for a warm-up but they do for a heavy work set
