January Jones In Bathing Suit Is 'Feeling' 27

January keeps herself trim via regular exercise, but she doesn't starve herself. "I don't get hungry until around 10 a.m., but since I usually do Lagree Pilates at 9:30, I'll make myself eat a banana beforehand so I don't get too shaky. Then I have a MacroBar afterward and eat lunch around 11:30—usually salad, soup, or a sandwich," she told Shape. Her exercise choices can be less conventional, though. At least, when it comes to location.

It's a do it when you can deal for Jones. The Mad Men alum added:

"Even when I was filming X-Men and they had trainers for all of us, I would lie and say I was exercising in my hotel room, when actually I was watching Friends and having full tea service.” The Mayo Clinic advises: "Get at least 150 minutes of moderate aerobic activity or 75 minutes of vigorous aerobic activity a week, or an equal combination of moderate and vigorous aerobic activity. The guidelines suggest that you spread out this exercise during the course of a week."

The mom of one, who has not revealed the identity of son Xander's father, continued:

“After I had my son, Xander, I wanted to feel strong because my body had changed so much. As he got bigger and I was hauling around a 20- or 30-pound toddler, my lower back gave out and I saw my shoulders starting to curl and hunch. I wanted to do something for my posture and core strength."

Mentioning that cooking is a family deal for her, the blonde stated: “I love to cook for my son and me. For dinner, we like salmon with french fries, and we make pasta frequently. We try to have lots of green veggies. We eat organic because I worry a lot about that for my kid."

Staying clean food-wise is important to Jones, who also noted: "No antibiotics or hormones in meats is really important to me, and so is eating sustainable fish. I don’t want to be that annoying person in the restaurant who’s like, ‘Where’s this fish from?’ But I do it anyway.”
