Every Friday night for the foreseeable future, Brooklyn Zumba Fitness is throwing Glow in the Dark Yoga Parties behind the Prison Ship Martyrs Monument in Fort Greene Park. For $10, yogis will get glow-in-the-dark bracelets and work through a sequence of asanas set to hip-hop music. It’s a nontraditional workout to be sure, but sounds like enough fun to replace your regular Friday night bar routine without missing a beat. Be in the park by 7:30pm and prepared to do some Adho Mukha Svanasana (downward facing dog) in the dark.
