I like her, too.
Always have. Chatty, but funny and laid back.
Before Cathe, Serious Curves was the only decent weight tape around (had to modify and repeat segments to make it advanced anough, but it worked). I gave it to my mom (God knows where it is now).
Step tapes and low-impact are all good, though some are better than others. Favorites are Benchmark, Step it off....
I do them once in a while, and usually stay w/them for several sessions before moving back to Cathe.
Moves are very basic--more straightforward and athletic.
Tempo usually slower, too.
But, all can be made more difficult--if needed--by increasing step height.
well-produced, too.
