question: why do i stay up until 4am when i perfectly well know that i have to be up in like 2 hours to get in school but i really dont care enough to actually get enough sleep because why would i be smart like that? lol if u get it right you get a free magic... whatever u want i guess

Well if you pick a machine to work on and that's gonna be your exercise if you don't stick to that machine your muscle strength your muscle mass rather will change because you haven't been doing it you change something in your exercise routine which changes your body's form of dealing with things for example you might become weaker or stronger depending on what kind of exercises you do in whether or not the machine you picked actually your muscles grow.
