Black Metal Yoga!
Nothing goes together like black metal and ... yoga?! Before you question it, you should check out Black Widow Yoga, a type of yoga that is targeted at the black metal audience out there, complete with the latest episode featuring an instructor rocking some corpse paint.
Instructor Borkkvlt (that's pronounced "bork cult") takes viewers through a black metal full body workout, unfortunately this workout is missing the black metal music, as copyright law kept the instructors from being able to include songs with the live stream.
However, there is a suggested Spotify playlist to assist your workout that can be found here. It includes cuts from Walknut, Rotting Christ, Ante-Inferno, Sodom, Carpathian Forest, Bathory, Akhlys and Hermoor, guaranteed to kick you into workout mode.
There are other Black Widow Yoga classes via the Metal Yoga with Black Widow Yoga YouTube page. Classes typically run between 30 to 45 minutes with a mat required. And for those appreciating the workout, classes are donation based with a suggested donation of what else, $6.66, per class.
