A former dance teacher, I trained as a Zumba® instructor in December 2010 when I couldn't find a class nearby. This happy accident has led to years of dancing fun with hundreds of new friends, a better understanding of fat politics while ironically, increased thin privilege from an excess of exercise.
The class policy is aimed at creating a body positive dance environment for people of all genders and none, trans or cis. Please have a read of it before you come along.
I occasionally write about body acceptance here, too (though of course it'd be better to seek out the writing of people with less white, thin and cis privilege than I).
