Holy Sore Hip Flexors, Batman!

Ok, so today was Day 3 of my 2nd "Full" P90X program (Full meaning I'm dedicated to sticking with it for the full 13 weeks...it's happening.) Anyway, I was very sore today! the worst part was my hip flexors. They hurt so bad that I had trouble standing upright to walk and when I did walk I looked like an 80-year old man. I got a lot of laughs and fun-poking from my "caring loving" co-workers. :) Surprisingly, I was able to do Ab Ripper X tonight after Shoulders and Arms. I was thinking earlier today that I wouldn't even be able to attempt it. Maybe it was the ibuprofen I took around 5pm...who knows. Dan
