I am taking a salsa dance class this semester.
If you don't think this counts as exercise, think again. The way you have to move for that Latin rhythm is just...unnatural.
Ow my back. Ow my thighs.
Picture to the right is Wulfy's sister and brother-in-law, not doing the salsa. They're dancing a rumba, actually, but it's the same family of dance. Imagine how strong she must be to hold that position.
