It's code for "when a 49-year-old woman tries it for the first time yesterday in a class taught by an 18-year-old, she can barely move the next day from the workout on her too-wide hips and creaky knees"
It's great fun and a great aerobic workout...set to Latin music with lots of Shakira-type wiggling!
Lissie, are you a Zumba regular? Do you find it's good for toning/dropping some pounds?
