Posterior Chain

Today I hammered my posterior chain, there is nothing left there, no injury just frick this hurt.

Sumo Deadlifts (started from top)
135x10
185x5
225x5
275x5
295x3
315x3
335x3
355x2

10-9-8-7-6-5-4-3-2-1 reps for time
Sumo Deadlifts - 225
Box Jumps - 30 inches
Time: 15:51

C2B Chinups - 3xmax reps......8, 7, 6

That hurt, I am very pleased with how the deadlifts went.  On the set of 275 I actually lost my focus for a sec and fell a bit forwards and it felt a tad weird on my back, nothing too bad so I decided to keep going.  The set at 335 was flippin heavy, but that's what I did last time so up I went, 355 is again the most I have ever done of anything....ya it was heavy for me.  I had in my head that maybe I'd try 3, but after the second rep I was done I wouldn't have gotten another, maybe next time.  Part 2 was really hard, I got it from sealfit which are notorious for developing very tough workouts.  The box jumps actually got easier as it went on, the deads did not, the first set of 10 was good because I went from 355 to 225 so it felt light in comparison, that ended on the set of 9, none of them broken though.  The C2B chins were thrown in random, so I guess not an entire posterior chain day, but they were hard after all the deads today.  Great workout!!
