Molly Sims and Gwyneth Paltrow have something in common: their trainer.

“Tracy Anderson has really changed my body since March,” Molly, 36, says during the ACE Awards presented by the Accessories Council held at NYC’s Cipriani 42nd Street this week. “Honestly, I have done a lot of different methods, a lot of different things, and I love it. I’ve seen the most results in my arms, my legs and my stomach.”

She continues, “I was talking to Gwyneth, and I was like ‘we all have the same arms.’ Yeah! I have arm strength and definition. I never had that before.”

The actress shares her routine.

“It’s an hour-and-a-half cardio, leg, arm, butt, stomach,” she says. “It’s hardcore. Six days a week.”

What advice can she give about dressing thinner?

“Know your body,” she tells me. “Know if you look better in a crew neck. Like, I know that I look better in v-necks and round necks as opposed to cap sleeves. Spanx are fantastic. Dress in black a little bit more on the bottom than on the top – whatever your area is – if you’re top heavy, dress in darker colors on the top as opposed to the bottom.”

But it’s not all about clothes for the actress who is launching her own jewelry line, Grayce By Molly Sims.

“You’re never fully dressed without jewelry,” she tells me. “I would feel naked without my jewelry. I love wearing it. I love accessories in general. Most days, accessories wear me. I love bags.”

What’s her inspiration for her line?

“My mom has been collecting for thirty years,” she says. “She used to go to estate auctions all over the world, and she would buy boxes for $10, $20. When I didn’t have a lot of money, when I was first starting modeling, I would have this really great jewelry, so I would end up buying basic things and building the wardrobe around the jewelry. I got known for that, and I always dared to wear statement jewelry. I’m a big layerer. I love mixing metals, and I was just like ‘I’m doing it.’”
