100 L pullups Workout

M/ 38/ 134 lbs/ 5'-6"
As Rx: 9:30
Pretty much no warm up.. just a few minutes of basic stuff in my home before leaving to the playground to bang this WOD out.
I did this last night, a little rainy, on a totally dark jungle gym metal monkey bars.
The rainy part kind of effected my grip, but it wasn't too bad.
I conciously broke them up into smaller sets to allow my rest/ break between working to be very little time. Less rest more work time is the key for me. If I go to failure, to get those extra couple reps will mean resting too much and then not being able to really push the whole time.
I rested for about 1 minute or so maybe 2 then did a D.U. ladder going from 5050 (5,10,15,20,..50) in 5:10
I need to slightly lengthen my jumprope I think.. I was o.k. if the sets were broken since it ws just a burner really. I normally can do lots of DUs unbroken but that number has gone down lately. I'm going to have to start back on working the DUs Post WOD I think.
For me, I was kind of leaning back a little bit when doing the L pullups, and I really did not feel my midline/ core too much. I was feeling it in my back mostly, even though I did a bunch of GHDs on my last workout.
