100 pull-ups for time

Went to the wifes xfit gym for the first time this morning. It was gloriously decrepit. Word is they are about to tear down the building and relocate- holes in the wall, falling ceiling tiles, exposed wiring- in short, it was awesome. Used the free-swinging pull up bars (also a first). Made it through the first 25 or so in about 90 seconds, the next 25 over about 5 minutes and by the time I hit 55 (kipping up until this point) I had to switch to a band to assist. My arms and back were shot. Finished in a total time of 18:08. Giddyup.
