It’s officially fall now, you guys. Landscapes are changing — as are the temperatures — and, if you’re lucky, so will your body (shape, not color — that would be weird). Celebrate your health and the changing of the seasons at Fall into Fitness, a festival featuring local food, fitness demos, live music and more. A healthy you begins at 11 a.m. Sunday at Farmers Public Market, 311 S. Klein Ave. Admission is free. Visit naturalawakeningsokc.com.
