i'm getting redic bad out of shape. the place i work at has a three floor staircase right next to my room/office. I decided this week that i would close the door and do pushups and situps over lunch in my office one day and run up stairs/walk down them the other day. embarrasssing i know but no one else will know about this (except you guys).
anyway, i just go done doing the stairs. feel like i used to after we would run a timed mile in highschool PE class. not good. sick to stomach, feels like someone punched me in the chest. could i be having a heart attack? tia.
