I did this one on my bike (outside on a very, very quiet road, yep, I use a mirror attached to my sunglasses to see any cars behind me) on Friday evening. Fabulous workout!!! Loved those sprints!!! Not sure if I was the lion or the gazelle, but I pushed hard for it. I'm looking forward to doing CC#7 or #8, which I still need to download to my mp3 player.
Most of all, Laura, have fun with your workouts!!! Life's too short.
