I taught kickboxing for many years, and I am not aware of any templates that you can use, other than viewing a few workouts from various sources. I do know that you may want to think about very simple moves, and putting in safety and form cues throughout your article.
Kickboxing is generally not something that you can just read about and know how to do properly. Specifically, execution of kicks and even some punches are not something to do without proper supervision. Furthermore, many people will not know what the kicks and punches are in print form if they’ve never done the workout.
That’s just my 2 cents and a few suggestions for you–just something to consider for your article. 🙂
