I also do most of my workouts from DVDs.
I track most cardio on my fitness page as follows("add cardio" "browse" "other exercises" "aerobics:general:low impact" or "high impact"). If I had a good workout and I sweat I use low impact, if I really worked out and was at the edge of what I can do, or if the workout was extra bouncy, I use high impact.
For strength training exercises without cardio, I usually use pilates or yoga to track the time just to make it easy.
This way I track both my minutes and calories burned for all my exercise.
You are never given a wish without also being given the power to make it true. You may have to work for it, however. - Richard Bach "Illusions"
