I am doing Zumba. I started last year but things started happening and I got off track with my exercise. Now with a bright new outlook on getting fit and in shape I'm heading back to something I LOVED doing. I have the DVD's but also watch videos on youtube to change my routine a bit. Oh and I also do DDR( dance dance revolution).
Its the only exercise I enjoy doing since I LOVE dancing, but Zumba's approach is most unique to most "dance" videos I've encountered. You really are moving with the music, every beat, rhythm etc, not just the usual instructional dance videos while going off beat with the music. I wish there were more videos like this.
