|Fortunately, most of the best hi/lo aerobics videos on the market fit the bill. Many are pretty highly choreographed, which can be frustrating for those with two left feet.
Kari Anderson's videos are especially popular among those who like complex choreography. Try DanceWorks,
Great Moves Hi/Lo or
Great Moves II, or
If you want something a little more advanced the CIA series has a lot to offer. Every last one of Christi Taylor's hi/lo videos, both her CIA productions and her independent productions, have extraordinary hi/lo sections. They're complex, but if you like that sort of thing, they are like a party in a box.
Greg Twombly is another talented hi/lo choreographer.
If you don't get into the dancy stuff, try
Aerobox, a boxing oriented video with Kathy Smith and Michael Olajide or
Crunch Master Class Aerobics.
