what is exactly going on physiologically that prevents you from lifting the weight over and over and over?
I understand you need more muscle fibers to perform the action as weight increases, but say if I am doing a OHP set with 130 lbs, and I can lift this 5 times and then I can't get the bar up again, but if I wait 20 minutes I can do the set again?
what resets in the body so you can push the weight up again?
what is the thing that 'runs out' during the set where you cannot lift the bar anymore? something with central nervous system? ATP running out?

muscle glycogen then blood glycogen. nervous system is a factor. oxygen a factor. a million other things.

>>41460076
ATP

consider working out at the library, brainlet

ATP runs out yea. Also CNS needs to recover because if you say max out bench twenty minutes later you aren't going to be able to repeat it

I doubt muscle glycogen is depleted
You have to run for 45 minutes or cycle for an hour and a half at an extremely intense pace to start making a large dent in muscle glycogen reserves
thats why some bodybuilders can be keto

incorrect. Please don't answer questions here if you don't know what you're talking about. The answer is primarily muscle glycogen and blood glycogen as was stated.

wrong

You don't run out of ATP. Ever. If you did you would die.
>>41460150
bodybuilders can be keto because glycolysis does not require glucose. there are multiple pathways of glycogen synthesis.
Also, you are fundamentally confused about what you are talking about. Muscle glycogen is depleted in seconds and restored again in minutes. But running out of muscle glycogen, and depleting easily consumed blood glucose, is why you run out of reps.

that's the point anon, what did you think "to failure" meant ?
