Of Cathe's, I have Slow and Heavy, Push/Pull/Supersets, Gym Styles, Pyramids and Basic Step. I think I have enough of hers already but if there's another tape really good for variety, please let me know! I do love the pace she lifts at although I'm not sure how much faster or more complex I could handle for her step routines.
I also have lots of the Firms - love the variety in them but sometimes I find they go too fast for me to follow smoothly. More patience and more practice would probably help a lot!
Just finished Dumb Training with Patrick for the first time. I'm amazed that in all my years of exercising, there were moves in it that I've never done before. I really enjoyed it.
