New killer exercises

I've added two new exercises to my repertoire. They were much harder than I originally anticipated. I guess everything looks easy. The reality was that the exercises were far from easy.

Offset barbell side bends (or lateral flexion as this vid calls it):

I actually held the barbell closer to the end. Three sets of six (each side) destroyed my obliques. I'm still feeling it two days later. Add the fact that I did deadlifts just before this exercise, and my entire midsection is sore.

Burpee pull-ups:

I don't know why I thought this exercise wouldn't be too bad. I could only do 20 reps my first set before getting gassed. Subsequent sets were down in the 10-15 rep range, and I was definitely breathing hard at that point.
