The cover of next month's Women's Running magazine already has people talking.

The upcoming issue has plus-sized model and real-life runner, Erica Schenk, gracing the cover.

Schenk was initially supposed to be part of a story on plus-size athletic clothing lines, but magazine editors were so pleased with the 18-year-old, they decided to make her the cover model.

"There's a stereotype that all runners are skinny, and that's just not the case," Women's Running magazine Editor-in-chief Jessica Sebor told "Runners come in all shapes and sizes. You can go any race finish line, from a 5K to a marathon, and see that. It was important for us to celebrate that." 

On "Happening Now" yesterday, Jenna Lee spoke with Dr. Michael Kaplan with the Long Island Weight Loss Institute and author Diana Spechler about the magazine. 

"A cover like this is so helpful because it allows any woman who's interested in running to identify herself as a runner," Kaplan stated.

Schenk joined Jenna Lee on "Happening Now" today, where she discussed how surprised she was to find out that she made the magazine cover. 

"I had no idea I was going to be on the cover," Schenk said. "I always wished that I would be on the cover of something. This is actually my first cover."

Schenk shared that she started running when she was 10 years old and that she lives an active lifestyle.
