Input: Text: i am overweight, hefty, whatever you prefer. i got an exercise trampoline to help change that. after having been swimming a lot lately and generally eating better, i decided to jump on it today, not for the first time. i jumped twice and metal flew from the side and scared the hell out of my cats. 

tl dr too fat to work out, not fat enough to be confined to a bed.

edit: thank you all so much for being encouraging! i start my next semester of college on august 25th and since we have a new campus, i get access to a great gym facility that i plan to use. i'm going to keep at it and maybe be able to show you guys some before and after in a few months.

TIFU by being fat and trying to work out.
