January's diet is all about moderation. "I don't deprive myself of anything. If I want something—steak, a bagel—I'll eat it. There's no diet or strict set of rules," she told Shape. She herself doesn't eat her first meal until after a morning workout. "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 revealed. "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."

January is a big proponent of green juice. "Last winter, I started drinking celery juice every day, and I've seen amazing results in my energy, digestion, and skin and how I sleep. I have that in the morning, then I take my vitamins and drink coffee," she told Shape. "Consider blending instead of juicing. Blending the edible parts of fruits and vegetables produces a drink that contains more healthy phytonutrients and fiber. Fiber can help you feel full," says the Mayo Clinic.

January eats organic, "because I worry a lot about that for my kid," she told Shape. "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."

January suggests putting the focus on strength, not getting skinny. "Being strong is important as you get older. I want to look and feel as young as I possibly can." Says the Mayo Clinic: "Do strength training exercises for all major muscle groups at least two times a week. Aim to do a single set of each exercise, using a weight or resistance level heavy enough to tire your muscles after about 12 to 15 repetitions."

January shied away from exercise most of her life, but was inspired to work out after becoming a mom and suffering from poor posture. "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," she told Shape.

January maintains that gaining muscle does a body good. She told Shape that once she started Lagree Pilates, her body changed. "I've been doing it two to four times a week for the past year now, and I've gained weight because I've put on muscle. I've gone up a size in clothes, but I feel like I look better." While she admits it is "quite difficult" she has found that it's the only thing that makes her feel stronger, "and I'm loving it," she said.

January suggests using a little friendly competition for fitness motivation. "The music is good and there's always a different routine, so it doesn't get boring. There are 10 of us in the class, and I like having women on both sides of me to push me," she told Shape. "When I did the private Pilates lessons a couple of years ago, I just saw myself getting lazy with it because there wasn't that drive for competition. For me, that's what's motivating. If there's someone strong next to me, I definitely want to up my game. I find myself looking forward to it more than I've ever looked forward to a workout."
