hotncmom, I’ve done a live CF class and the yogavibes class, and they were more or less identical. The cardio effect comes from doing lower body movements w/ upper body light weights (for example, Warrior 2 pulses w/ bicep curls, speed skaters w/ tricep lifts, static lunges w/ overhead lifts, etc.), kickboxing -type movements, balance/toning moves (for example, balancing on one leg, doing leg lifts w/ the other as you work your triceps), and lots of mountain climbers between the blocks of toning work. I think the structure of the workout (toning/balance segments alternating w/ cardio bursts) and the fact that it is done barefoot and on a yoga mat make the time fly and it doesn’t have the dread factor that some other cardio workouts do. I also love that it includes toning, cardio, balance, and core work.
The yogavibes clip gives you a pretty good idea of what to expect:
