I just completed Day 2. It actually was not as bad as the Fit Test, although it was about 15 minutes longer. It mixed circuit cardio with stretching, so that made it bearable. I did the first two rotations pretty well (a whole lot slower than the people on the video, but I could actually do the exercises). The last rotation was pretty much impossible. I just did the best I could, probably doing 1 rep for their every 5 reps! Yes, it was that hard!
I'll see if I can walk tomorrow! My fitness friends convinced me that strengthening my core muscles and improving my flexibility will benefit my running, so I am going to continue to TRY the Insanity workouts 3 days a week.
I may quit again tomorrow when I see how I feel! I'll keep you posted!
