I love both of the PRS routines! PRS 2 is more athletic and physically demanding, while PRS 1 is more intricate and mentally demanding, but both are great in their own way, and the premixes that combine them are so fun.
I will never forget that the first time I tried PRS 1, I ended up with 12,000 steps on my Fitbit because I kept rewinding and trying again. But I don't feel frustrated when I don't get a Cathe step routine on the first try or three, because I know when I get it, it will be so fun and so worth it!
Also, I enjoy having the option of a cardio workout that does not exhaust me physically but does challenge me mentally. I put PRS 1, Step Moves, and Rhythmic Step in this category.
