Midway through their yoga class, the teachers realized they need a megaphone.
Cars honked and a DJ was playing funky tunes as dozens of arms reached toward the sky.
More than 100 people had brought mats to a parking lot on Lyndale Avenue in Minneapolis for the fifth session of Gorilla Yogis -- urban, studio-free yoga that's springing up around the Twin Cities this summer in various forms.
Their name is an offshoot of a fringe movement known more widely as "guerrilla" or no-frills yoga. Regardless of the name, it's defined by a focus on the essence of yoga without the trappings of accessories ($90 yoga mat, anyone?), an effort at affordability (prices range from free to a sliding scale to a charitable donation) and sometimes a slightly underground nature.
Yogis have been seen practicing the downward-facing dog at the Mill City Farmers Market or the triangle pose by Lake Calhoun.
"At our Mill City event, people showed up in tennis shoes, with their dogs, without mats," said Nan Gane Arundel, one of the leaders in the local movement. "We're reinforcing that you are already whole; you don't need anything else. I find that really liberating."
Arundel and Jessica Rosenberg founded Gorilla Yogis in March, looking for a way to practice yoga in urban, offbeat places, and to build community, raise money for local causes and create awareness for yoga. After posting their first event on Facebook, about 150 people showed up at the Mpls. Photo Center on a fluke 80-degree day.
"A lot of times yogis tend to go to the same places and don't get out of ruts and patterns," Arundel said. "We wanted to find out, How do you do something different, how do you tear down the studio walls?"
