Day 1: what started out as exciting soon proved that I had a core. I always knew I had abs (hidden deep down inside), but I had no idea they would be screaming at me so much! I can't wait till tomorrow to do it again! I figured this DVD would be a good idea since I finally committed to doing the Tackle the Tower race and, since it requires climbing 37 flights consisting of 646 stairs, I figured it would be smart to start building up those quads. Afterall, I only have 24 days for this miracle to occur!
