I don’t know why I thought the yoga classes at the Eco Yoga Park outside Buenos Aires would be in English, but they weren’t.

Here’s my cheat sheet, which I’ve compiled after three months of taking yoga classes all over Argentina, to get you started with your international practice. So get on your colchoneta (mat) fearlessly, and when all else fails, you can always peek around!
