Why the HELL do I do this?

Today's Crossfit WOD:
Do pull-ups until your hands look like this:



Ok, actual WOD for Wednesday 080806

45 pound Dumbbell squat snatch, left arm, 21 reps
45 pound Dumbbell squat snatch, right arm, 21 reps
42 Pull-ups
45 pound Dumbbell squat snatch, left arm, 15 reps
45 pound Dumbbell squat snatch, right arm, 15 reps
30 Pull-ups
45 pound Dumbbell squat snatch, left arm, 9 reps
45 pound Dumbbell squat snatch, right arm, 9 reps
18 Pull-ups

Scaled to 20# on the snatches; went to band assisted pull ups by the last round. Hands hurt so bad. Didn't time it. It took roughly forever (somewhere in the 45 minute range), mostly due to the fact that I had to talk myself into grabbing the bar after I dropped on every third pull-up. At one point I even told myself that I'd been through labor, so I could get through just three more pull-ups. Then 3 more, then 3 more.... The frustrating thing is, it isn't the muscle aspect of the pull-ups (at least if we're talking kips; strict is another story). My back is fine, arms are fine: it's my grip and (for this workout) the literally blistering pain in my hands. Towards the end of the second round, the CF'ing trainer at my gym vertical taped my hands...that's prob the only reason I didn't DNF the pull-ups.

Urg. I feel lame.
