In March 2022, Brianna Joye was feeling lonely and isolated at home in New York. Her girlfriends had moved out of the city during the pandemic, and she missed their walks and coffee dates. The professional dancer turned fitness trainer decided to take a chance: She asked her 1 million followers on TikTok if anyone wanted to maybe go for a Sunday morning walk with her in Central Park.
“I was really nervous. I expected maybe 10 people to respond,” Ms. Joye said. More than 200 girls showed up. “We walked for about 40 minutes, and then I decided to do this every single Sunday.”
