Kate Upton kicked off her Friday on the right foot!

The 23-year-old model enjoyed a morning hike with some friends at Runyon Canyon in Los Angeles, still managing to look flawless without any makeup on.

Upton also showed off her famous curves as she rocked some skintight workout clothes, wearing a pair of black leggings with a blue and black zip-up sweater.

Whether she's hiking or hitting the gym, the Sports Illustrated cover girl is always working on her body. But despite how many people think she's flawless, she admits she still gets shy about her curves.

"I always am!" Upton told the London Evening Standard earlier this year. "Well, I am and I'm not at the same time. Every person has insecurities. But this is the body I was given, I appreciate it and I try to take care of it every day as best I can, but I always enjoy my life. So I'm not going to let my insecurities stop me from enjoying life."

Whatever she's doing it's working for her! In fact, just last month the model showed off her incredible body for a sexy photo spread in V magazine.

In the photo, Upton poses on her back, wearing white lace La Perla briefs over a mesh bodysuit, which was peeled away at the chest to reveal one bare boob. She cups both of her breasts with her hands and gives the camera her go-to sultry stare.

Just a few days before that, the blond bombshell also modeled for the first ever CR Men's Fashion Book—a supplement of CR Fashion Book by Carine Roitfeld—which is expected to debut later this month.

"Kate has always been everything I love. She is the opposite of me. A Marilyn of today," Roitfeld said with regards to why she chose Upton for the magazine. "For my new CR Men's Book, she represents different types of beauty and the sexual fantasies of all men."

Amen!
