just wondered how many zumba classes you are all doing across the country. i'm doing 3 right now. i did a 4th last week but i felt that i didn't work hard enough with a different instructor (in fact i think i was fitter than her). my usual teacher is just exceptional. also do you do tracks back to back (which is what my usual instructor does) or do you have 2 min breaks between dances (which is what the different instructor did)?
