Cathe offers several floor cardio routines, most of which are cuddled up among other modes. The floor cardio (both traditional hi/lo and kickboxing, not to mention Boot Camp which I'll mention in a minute) is so good on its own it'll be worth the expense, even if you're not interested in the step segments.
Maximum Intensity Cardio ("MIC" to the seasoned Cathe-ites), contained on the same DVD as Rhythmic Step and Interval Max (the step interval routine that got Cathe's rep as the queen of interval workouts started; mother of I-Max 2 and I-Max 3)
Step Jump Pump ("SJP"), contained on the same DVD as Step Blast; there is a segment that consists of four 4.5 to 5-minute hi/lo cardio interspersed with resistance circuit cycles; there is also a premix called "Hi/Lo Add-On" that is strictly the hi/lo segments;
Circuit Max and Cardio Kicks (one DVD; two great workouts); Circuit Max is the pre-eminent circuit routine with 6 5-minute segments of cardio interspersed with 6 2-minute compound (upper+lower body) weight resistance cycles; the first two cardio segments are incredible hi/lo, the third cardio segment is floor kickbox; the fourth cardio segment is step-kickbox and the last two cardio segments are traditional step. It is very easy, after each cardio segment, to grab the remote and fast-forward through the resistance cycles. Cardio Kicks is a "kickbox-flavored" floor routine that has an extended steady-state cardio focus for the first 35-40 minutes and a 15-minute power drills segment that is interval focused. (Love love love the power drills segment.)
The Cross Train Express series ("CTX") contains 5 cardio+weight workouts and a stand-alone leg workout as its sixth workout (four of these also include floor and plank core/ab work), and the cardio includes hi/lo and kickbox. Great value, and probably a good addition to your weight training system as well.
Boot Camp (on the same DVD as Muscle Endurance) has 8 nosebleed cardio segments that are floor oriented; there is a cardio-only premix. The Cardio+Lower-Body premix is good for elevated heart rate as well.
Kick Punch Crunch (on the same DVD as Legs & Glutes) ("KPC") and Kick Max (on one DVD) are also good floor cardio with, of course, a kickbox focus.
Hope this gives you some ideas!
