Hi Anna,
I have both Powerstrike videos and use them on days when I don't feel like doing high impact cardio. They start with the basic punches like jab, cross, & hook and build up in speed and combinations. They go onto the leg kicks... starting slow then building up speed and adding kick and punching combinations. I think the videos do a good job of working many different muscle groups in one workout.
I bought my set from cksales.com (1-877-438-3480). They are located in Canada and were less expensive than powerstrike.com due to the exchange rate.
Hey Stacy...I totally agree with video #1 and the back lunges. I made the mistake of doing it right after PowerHour last week and I had to take the next two days off because I was so sore. Those back lunges are killers. :-tired
