Input: Text: this happened just under 24 hours ago but i am still feeling the effects now.

i had gotten into pretty good shape about 2 years ago. not amazing, but fit. then my daughter (second child) was born and exercise ceased. in the last 2 years i have worked out twice. my wife has mentioned a few times that with things settling down a bit more she'd be ok if i started working out again. i signed up for the gym and went yesterday.

the routine that worked really well for me is called stronglifts 5x5 - and a key component of this routine is squats. my gym only had 1 squat rack and it was being used by a guy - but the guy was friendly and amenable to taking turns for our sets. he was squatting 135.

here's the fuckup - when i was exercising regularly (2 years ago) i was squatting nearly double that. 135 didn't seem that bad and i didn't really want to have to change the weights every time we 'traded' i decided to just go for it. it was a fairly easy workout - a bit tough by the end, but nothing too bad.

i get home and everything is fine - i shower and relax, but a little while later i go to turn a light off and i collapse onto my knee. i'm able to work myself up to my feet and laugh it off. a little while later i'm walking up some stairs and i fall at the top of them, unable to get back on my feet - i have to scoot to the stairs and use them to stand - then carefully climb up the remainders. half an hour later i take a step down the stairs and my body just sort of collapses downwards, crushing my knee underneath myself pretty harshly. now i'm being careful - walking up and down stairs like a dog, keeping my hands on walls to steady myself. everything seems to settle down.

put the kids to bed and go to the basement (scooting down the stairs on my butt) to play some games and relax. four hours later i go to climb up the stairs and i can't. i am literally unable to climb a single step. i sit and 'carry' myself up the steps one at a time. now i'm up here but i can't stand. i crawl (in a sitting position) to a footrest and pull myself onto it. i'm then able to use a nearby chair to pull myself up to my feet. i'm barely able to make it up to my bedroom and when i lay down i have to drag my legs into bed after me because i can't lift them.

i woke up today feeling quit a bit better, but they're still weak. stairs are terrifying and every time i sit or stand it's a mess. strangely enough i'm not really in much pain - my things are simply non-responsive.
