I tend to meet challenges from friends head on, as if I have to prove to them I can do it. I'm not sure why I always felt like I needed to prove myself, but I have.
My trainer, has on occasion, "challenged" me to a few different things. About a month ago, I won $5 for completing my last set of jumps, and last week...well, I won a sort of different challenge.
Matt has this habit of making me do something so much, I end up hating it. Something I hated one month can be easily replaced with something else. For the longest time, I hated shoulder presses because he made me do them ALL the time. I would groan and moan every time he made me do them. Well, a few months ago, this was replaced with girl pushups, we started out small, three sets of 10, then three sets of 12, three sets of 15, and then last week three sets of 16. I was PMSing pretty bad last Wednesday and put up a stink about doing them, so he made me a challenge: If I could do one real pushup, I wouldn't have to do three sets of 16 girl pushups. I quickly made the deal. I got down on the ground and did a single pushup. He said a deal was a deal, and we walked the track and did my second favorite thing in the world (sarcasm): shoulder presses. We got back to the mat, and Matt says, "A deal is a deal, you won't be doing three sets of 16 of girl pushups, I want three sets of 10 of the real thing." My mouth dropped, and I slipped under my breath, "Jerk!" He kept his end of the deal, now I had to keep mine. I didn't get three sets of 10 of real pushups in (muscles fatigued), but it was a start. Next time I won't open my big mouth, OR...only accept a challenge after I really think about the aftermath. :)
