For the cardiac output work, basically LSD, you can use any modality or mix it up if you're getting bored. It's only targeting heart rate, so as long as you're in the target heart rate range, the exercise choice doesn't matter.
Jump roping works well for the active recovery that's prescribed in many of the workouts. Joel has you rest for like 5-10 min. between many of the circuits or series, as I think he calls them.
