I can admit failure. I have completely failed in my quest in the 100 push-up challenge. I'd like to blame my girlfriend who was going to do this with me when she injured her elbow, but the failure is really all mine.
I couldn't tell you when it happened, but one day I just stopped doing push-ups. Sad isn't it? I'm not surprised, I've never been able to stick to an exercise plan.
The up-side to this is that I can do 20 push-ups in a row! That is 10 more than I could do when I started...and those first 10 I can do without batting an eye.
