I made a playlist on Youtube of songs that have dances that go with them (Cupid Shuffle, The Wobble, Electric Slide, Cotton Eye Joe, etc) so that when I want a fun workout I just start it from the beginning and dance! I have enough songs that it makes up a 30 minute workout and it just seems like I"m having fun. Try it!!
Some fun ones that are not as well known that you might like to learn and try: on Youtube look up "Michael Jackson Shuffle" and "Biker Shuffle". Very fun!!
