Adonis I am not

Yesterday, before going to bed, my stomach started aching pretty badly. I tried to think of what I might have eaten to upset it, but couldn't come up with anything. Then I remembered that two days ago, on a whim, I had done thirty push-ups in the living-room of a friend, leaving me with an incredibly sore chest. Could it be that my abdominal muscles had, as well, united against me in painful protest? Could it be that during my weeks of sloth and lethargy they had grown accustom to their state of repose? In a word: that is absolutely the case. Due to my lack of daily exercise my abs had become sore to the point of painful cramping, which I was able to alleviate only by sleeping on my stomach. I am so ashamed.
