A couple of San Antonio yoga studios are taking part in the Free Day of Yoga, an annual multi-city event to promote yoga. The event is scheduled for Sept. 1.

The Union will offer nine 60- or 90-minute hot yoga sessions at its locations in Alamo Heights, Hollywood Park and Huebner Oaks. Schedule and location info here.

It’s worth contacting your closest yoga studio to see if it’s offering any free classes. Many studios in Austin, Dallas and Houston also participate.
