There's no stopping 24-year-old supermodel Joan Smalls' domination of the modeling industry, but seriously, who would want to? Models.com recently named her the No. 1 model in the world and, judging by her latest spread for Harper's Bazaar UK's October 2012 issue, rightfully so. 

Within the issue, Smalls discusses just how she remains in picture-perfect shape. 

"Four years ago, it hit home that my body is part of my business so looking after it became part of my lifestyle. I started training with Mark Gordon [the personal trainer who works with many top catwalk models]," Smalls says. "Personally, I put importance on every aspect of modeling and taking care of my physique is one of them."

And the leggy brunette doesn't just take over glossy magazine pages. Next up, she'll be co-hosting MTV's revamped House of Style, which premieres October 9, with fellow supermodel Karlie Kloss.
