Punk Rock Aerobics happens Wednesday, September 15, from 6:30 to 7:30 p.m. Admission is free. Sacramento Public Library, Central branch, Tsakopoulous Galleria West Meeting Room, 828 I Street; (916) 264-2700; www.saclibrary.org.
The right music is key to an effective workout. Science has yet to prove it, but we suspect the tinny, overproduced yodels of Katy Perry’s “California Gurls” actually sap muscle strength when played repeatedly over a gym sound system. By contrast, the poppy chord progressions in the average three-minute Ramones song supply enough energy to carry any athlete around the track in record time. Don’t take chances with your health. Get the most sweat for your effort with Punk Rock Aerobics, a free class taught by the Sac City Rollers’ Lipstick Librarian. Accelerate your heart rate with tracks by L7, Fugazi and other punk giants this Wednesday night. Did we mention the Lipstick Librarian will be blasting her custom soundtrack inside a library? How punk is that?
