Haslina,
I second the Kathy Smith kickboxing video. Aerobox is actually boxing, with no kicks, but it's a good workout. If you're looking for excellent form instruction, you might want to try Katalin Zamir's GI Jabb video set. The intro tape is a very thourough 50-minute "how to" session on punches and kicks. Some find her style a bit dry in the workouts (I liked them, but they are not advanced enough for me now and I sold them a while ago). Collage video has the 3-tape set and you can see more info on their site. (I hesitate to mention the following, because it's not the reason I posted and seems self-serving, but I have two beginner/intermediate kickboxing videos for sale on Ebay. Check under "Clafouti" (my seller name) and see if you like either of them. Both offer good instruction, but "Kick It" with Antoinette U. might be better for beginners. I hope this doesn't count as an infraction of the "no commercial posts" policy. If so, I apologize.
