Much like the Buddha's go-to concentration technique, people. Isn't it ironic?
Always keep safety first
With all this rolling around and squatting next to open bottles, I was impressed when the class ended with only three spilled beers (granted, one of them from someone who couldn't quite master tree pose while balancing a bottle on her head) and miraculously also with no shattered glass.
Obviously, drinking while doing yoga has its dangers -- that's why you sign a release form at the beginning of class -- so it's important to always take it slow and listen to your body.
I wouldn't recommend doing yoga while drinking wine, vodka, or anything else with a high ABV. Plenty of practitioners swear by smoking weed during yoga, and I'd argue the happy, relaxed buzz that beer gives you could have certain similarities -- in appropriate amounts, of course.
Overall, it's not a real workout
True yogis will probably find this entire account totally blasphemous. I'll admit that as far as fitness goes, I broke out in a sweat just a couple times, and then only barely.
