I love it. Love the Latin tunes, grooves and moves, love the sweat it works up and I just have a great time doing it.
Here's a little taster I've sourced from YouTube for anyone not too familiar. It's a pretty old video from way back in the beginning: it's short, funny, the instructor is good and doesn't take themselves too seriously and it epitomises for me the fun of it all. I can never work out whether some of the participants in this videa are members of the audience genuinely joining in or whether they're part of the Zumba troupe, but some of them are funny.
