I occasionally do stomach crunches -- not as often as I should but more often than I used to -- but I hadn't done a full sit up in . . . oh, I dunno, 20 years? So, I was watching this fitness video and they were talking about the benefit of a full sit up so I thought I'd try them.
Pathetic. First try, I couldn't do one -- doing it the way they say to do it which is: feet flat on the floor, hands held like they're over your ears. I just couldn't get all the way up. I could do it if I rocked my arms forward a bit but keeping my arms bent with my hands over my ears . . . took me several tries. I eventually got 9 done but man . . . I don't remember them being so hard.
