P90X Day 20: OK, not Kenpo, I did BBL's Bum Bum

It's 35min, and I did it with my DD.  Whew!  Not easy!  Definitely built up a sweat, and worked the legs and butt.  I could definitely feel it the next day, but doing Bum Bum the day after Legs & Back was pushing it, because my legs were a little worn out.  I'll have to think about what to do in Week 5, 6, 7 on day 6
