2011-03-18 Friday Crossfit

I modified a workout from the main crossfit site.
The original crossfit wod for 2011-03-18 was...
Four rounds for time of:
10 L-pull-ups
15 Push-ups
15 Chest to bar Pull-ups
15 Push-ups
20 Pull-ups
15 Push-ups

I did the first 2 rounds with reps Rx but tuck instead of L pull-ups and then on rounds 3 and 4, I reduced all pullup reps by 5.

23:00.
