One Hundred Pushup - Initial Test

I started the challenge for the OneHundredPushups program. The first step is doing the initial test which helps to determine which intensity level of the program you need to use to get your body ready for the challenge. Basically, you do as many good-form pushups as you can then from there you move into the actual weekly program.

I was able to do 15, though I'm really only counting 13 as good form - I started to arch my back too much at the end. That puts me at the high end of a Rank 2 or the low end of a Rank 3, but that doesn't matter much for the actual program as either way I'll be using column three. So now a day of rest and then I start the first week, going from Thursday to Thursday.

Anyone else crazy enough to take this challenge? Post in the comments if so.
