What are some tips for creating and executing an excellent cardio kickbox class?

Thanks Steve! I would actually go onebetter on the kicks as far as teaching types of kicks.
As a martial arts instructor, I spend a great deal of time teaching the proper stance and foot placement when performing a particular kick. Certain kicks are more difficult to perform than others.

My peeve is seeing the side kick being performed without pivoting the hips so that the heel of the standing leg (with knee bent) is pointed in the direction of the kick. Yet another bad thing – knee injury!! Same applies to the roundhouse which I never introduce until the sidekick is mastered because you need to pivot even more!
