There are many. I love DM and LIC. Whenever I have extra time, I repeat the cardio segments and go as heavy on the weights as I can properly handle. I also love Intensity. I burn 450 to 500 calories during the 30 min step segment alone. It is the highest calorie burn I ever got from any 30 min workout. It is my favorite Cathe step, pure fun.
I like to do the first half of AT followed by AB or CS. I learned that if I add the solid step segment from AT before other workouts my calorie burn goes up. I was glad to see another step segment on TTM. I also like to do the first half of AT followed by all of Tabatacise. With Tabatacise, Cathe took what is in my opinion a mediocre form of cardio (tabata) and turned it into an intense fun cardio by inserting the step segments in between the Tabatas. It was a touch of genius. Sometimes, I repeat the step segments even if it means not completing all the tabatas. There are many others like the Terminator workouts, HSA and many more. For my body type, any cardio workout that includes controlled cardio-weights works great. Needless to say, X10 is going to be at the heart of many premixes which will include Hi rep, FT, and many more. I know I will need to work up to them because X10 was plenty tough as is. I often wonder if Cathe uses a HRM when planning her workouts because she does a great job controlling the HR from start to finish. You get a break right when you need it even when you don't know you need it.
Liquid Heat was DH's description of what I look like when doing these workouts. He does them too and looks just as soaked. We have a running joke about how many degrees we raised the temperature in the room during the workouts. I own a lot of workout DVDs. There really aren't many that come anywhere near the intensity of Cathe's.
