Workout Program with hand weights

This is a workout program that I made up over the summer, and I had my sister and some friends over at my house doing this with me. If you don't know how to do some of the moves, go to youtube.com and type in the name of the exercise and I am sure you will find oodles of videos on how to do the workout. Let me know what you think of this workout. Do the workout every other day.
