Denise Richards has had two kids and several public break-ups yet she seems to still manage to stay healthy.

OK Magazine sat down with Denise and got the scoop on what she's does to keep fit and healthy through it all:

OK: What's the best part about exercising?
DR: I feel healthy and strong, and I love how I feel mentally and physically. This is the first season in a long time that I have felt comfortable on the beach without a sarong covering my bottom.

OK: Do you find stress causes your weight to fluctuate?
DR: Stress definitely affects my weight. I am thinner when I'm stressed or have a lot going on.

OK: With such a busy schedule, is it difficult to find the time to exercise?
DR: No, because it is part of my lifestyle. I don't work out only when I'm preparing for a project or shoot or bikini season. Exercising is part of my routine. I try to do it five days a week for an hour. That's an hour of time to myself, unless the girls come in, but that's okay too. That's the luxury of working out at home.

There's more on working out with two young daughters as well what she wants to instill in them about body image, so read more

OK: Is it hard to get motivated with two daughters?
DR: No, my girls motivate me to exercise and eat right! I am a single mom, so I am outnumbered! I need my energy to keep up with them.

OK: How did you lose weight after having your daughters?
DR: I am naturally thin, and I feel that I am at a good weight for my body. I work out to be lean and have some definition. Of course my body went through many changes having two babies back to back. For me, losing the weight wasn't that difficult; I was lucky. And no, I didn't work out five hours a day, I had to wait six weeks to do anything after each baby because I had a C-section with each birth. I took it very slow getting back into my routine.

OK: What will you hope to instill in your daughters about body image?
DR: I will try to teach my daughters to love their body. Sami was looking at Lola and said, "Wow, look at Lola's big belly," and I told Sami that Lola has a beautiful belly. Now, Sami tells her sister her belly is beautiful.

OK: Who do you think has the best body in Hollywood?
DR: Demi Moore still has the best body in Hollywood!

OK: What are your favorite food splurges?
DR: Chips and guacamole. And ice cream!
