Join The Boombox Studio for socially distanced outdoor fitness classes each Sunday at the San Francisco Ferry Building’s back plaza. These small group classes combine a fun, funky playlist with fat-burning, muscle-building moves – not to mention waterfront and Bay Bridge views! Sign up via the Boombox website or app (no drop-ins available). In accordance with San Francisco Department of Public Health guidelines, classes will be capped at 12 people. Classes offered at 10am and 11am
