I just did Cardio Camp for the first time a couple of days ago and I highly recommend it. You don't need any equipment. It's a nice variety of hi/lo, kickbox and non-weighted leg work with some balance moves. It's not complex and Kimberly is excellent at cueing. It had a fast pace and was not hard to follow. She does 3 combos with a hi/lo combo followed by a kickbox combo. After that's over, she puts all the hi/lo combos together and then puts all the kickbox combos together. Then she goes on to the legwork. She does curtsey lunges into a side balance. I can't remember the other moves at the moment. Think of the hi/lo from MIC (without the high impact, although she does do some jumping jacks, jump rope and power scissors but not for very long) and the blasts from Low Max and kickbox. This was so much fun and one of the best cardio routines I've done. It kept my heartrate up throughout the whole workout.
I would also recommend Amy Bento's Hi/Lo Xtreme. This one has athletic choreography which was not hard to follow either and also kept my heartrate up throughout. I liked the music on this as well.
