I did Zumba sometime back but went back to jogging and walking as my mode of exercise. I just incorporated Zumba again back in my regimen so I don't get bored doing the same exercise over and over again.
The movements really make me jiggle my body and I am working my core muscles as well with the arms and legs movement. I like this dance exercise a lot. It's not so hard to follow as long as you know the basic steps. Zumba also incorporates other latin dance movements like merengue and salsa and the one I am following has hip-hop added as well. So you can imagine how tiring it is to complete the half and hour routine. But I think it's really worth it.
