Input: Text: the mandatory this happened yesterday and not today. also this is my first tifu post.

first for a little backstory. 2015 was a rather busy year for me. i had graduated college, gotten a job, gone to some weddings, got a new job, moved to a new state, joined the army reserves, and got a girlfriend. 
 
while in college and since getting out of the active army in 2012 i had been very much into going to the gym and lifting. i ended up passing all my goals multiple times as i would set new goals about every couple months i would pass them. i had been very much into lifting now since about 2010 and i hadn't really taken a very long break since then until may 2015. 
 
from may 2015 until just yesterday i had not gone to the gym. making me feel the need to go especially since i joined the army reserves and have since gotten out of shape, especially with running.
 
yesterday i decided it would be great to start working out again! it had been a while and i have been telling myself i would like to get back in shape and then get into better shape than i was before. i'm currently 180lbs with 13%bf and about 5'9". i use to be able to lift a decent amount compared to your average gym going.
 
so yesterday after getting out of work i went over to our local gold's gym and got the 7 day pass in order to make sure i'd like this particular gym. 
 
on the way to the gym the "good idea fairy" popped in my head.
 
gif "wouldn't it be great to kick start your workouts and your week by doing leg day first????"
 
me "hell yeah! get leg day out of the way and kick start the week"
 
this is where i should of known i fucked up! i get to the gym and do all their normal bullshit to get the 7 day pass. 
 
finally i'm signed up! i ask where the squat racks are and i walk over to the triumphantly thinking i'm going to have a great squat day! boy was i right! yesterday was a great squat day considering i haven't been in the gym since may of last year. i was able to squat 225lbs still for multiples of at least 3 for a couple sets. 
 
i text the girlfriend telling her, showing off to make me seem sexier, that i can still squat 225 and how pumped i am!
 
i finish my leg day and award myself with some much deserved sushi. my legs are pumped and i can tell they're going to be sore the next couple days.
 
fast forward to this morning. i wake up and get out of bed. my legs are stiff! they don't want to move and every time they do move they cause a huge discomfort, not pain just soreness. i hobble over to the shower in order to try and wake them up but wait i've got to take a shit! i try sitting down the toilet like normal but no! i'm about to fall! i grab onto the sink and slowly lower myself onto the toilet.
 
now i'm at work and walking around makes me look like i've got a huge fucking stick up my ass as i try to shimmy my legs to walk. i work on the 4th floor and thank god for fucking elevators!
 
the worst part is that today is chest day and the 2nd day is always the worst day for all the soreness. all the weights are on the 2nd floor of my gym. i almost don't want to go but i must strive on!
