This photo is a tame representation of what will go down on Friday.

For the past year, Kelly over at WorkshopSF has been throwing a regular metal dance party/group exercise session/excuse to drink more cheap beer dubbed “Heavy Metal Aerobics.”  Basically, instead of going to a gym and listening to some upbeat techno music and following the moves of someone way more fit than you, some regular-ass aerobics instructor helps you get fit and blasts Slayer.  Even Lydia of Hater Tuesday digs HMA, and that trick hates everything.

Anyway, to celebrate the one-year anniversary of HMA and its move from the Wester Addition to the Mission, Kelly's throwing one epic party at Engine Works this Friday:

The infernal gates of Hades (aka the doors at Engine Works [190 Capp St.]) open at 8pm with DJ's Sarah Doppler (Pop, Be Excellent to Each Other), Mike Gerardo, and Donnelle Malnik (THE Heavy Metal Aerobics Instructor) each spinning the heavy/hair metal tracks. At 9pm, the eardrum annihilation begins in the Engine Works basement with metal overlords Hightower, followed by the wicked guitar wizardry of Hot Lunch.

But if you are thinking of catching a breather between sets…. think again. Instructor Donnelle Malnik will lead a Heavy Metal Aerobics workout medley during the break, complete with HMA girls clad in leopard print body suits and legwarmers, teased out hair that could eclipse the sun, and of course our own Workshop beer can weights! Aqua Net hair teasing and groupie makeup stations will be offered for the ladies and the glam rock boys. Prizes (including custom heavy metal vests) will be awarded for most heavy metal aerobics inspired costume. And don’t forget to lineup a few of our Jack Daniels cupcakes.

Sweet!  Tickets are $10 and you can get them over at WorkshotSF.
