It took me a week of doing it daily to get HIS & another week to get LIS. The first day I did HIS, I spent 15 minutes doing the warm-up, rewinding & then doing it again & again; then another 15 minutes doing the same for the first step routine. I wouldn't move on until I had each section learned. After 5-6 times, I finally got it, although I still have days where I seem to forget what to do with the step hitch-kick....
It seemed to take forever to learn them, but now that I have them down, I love them to pieces!
