Today's Workout

So I have been lagging on the blog.  I stopped doing GOMAD since I took some time off and haven't been lifting heavy.  I am still holding steady at 171 so that's great.  My workout today was:

5 rounds for time of 
20 Double Unders
20 Wall Balls (20#)

It took me 15:40.  I suck at double unders so that's what slowed me down the most.  I have not spent a lot of time  trying to get them down and have a hard time stringing them together.  I usually do one double under followed by a single then a double under and so on and so forth. Tomorrow morning I am going to wake up bright and early and CrossFit at 6:30 am.  The WOD is 4 rounds for time:
30 DUs 
10 Deadlifts 185/115

Yay more Double Unders!  I will probably do 115 or even 100 for the Deadlifts since the last time I did it I injured my back.  I feel healthy but I am going to keep it light. Even at 115 that is 4600 lbs of deadlifting and I got injured deadlifting a volume of 4305.  That 4305 was at a weight of 205 though.  So my question is, will higher volume at lower intensity hurt my back?  I don't think so.  It is kind of like a sprinter pulling a hammie in the 100m.  Will a  light 400m reinjure them after the heal?  No.  Nonetheless, I will do some research just to make sure and let you know.
