1. She Didn’t Start Exercising Until Later in Life

January didn’t really get her sweat on until after she became a mom. “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 explained to Shape.

2. She Loves Pilates

January’s workout journey started with barre classes, which led her to what is now her go-to workout. “Then a friend told me about Lagree Pilates,” she told Shape. “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 naked.” 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.”

3. She Is Into Group Fitness

January likes to take group fitness classes because the “music is good” and the routine varies so “it doesn’t get boring.” In her class there are 10 women, “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.”

4. Moderation Is Key with Her Diet

“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 dished to Shape about how she eats. She also follows her hunger pangs and fuels herself prior to exercise. “I don’t get hungry until around 10 a.m., but since I usually do Lagree 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 has one favorite 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.

6. She Sticks to Organic Food

January sticks to organic foods, “because I worry a lot about that for my kid,” she explained to 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.”

7. Her Goal Is Strong, Not Skinny

For January, staying in shape is about strength, not being skinny. "Being strong is important as you get older. I want to look and feel as young as I possibly can."

Jones opened up about her life and career in an interview with Shape. She says that she isn’t embarrassed anymore. “I feel comfortable in my skin,” she says. “Public opinion doesn’t matter to me. Yesterday I went to a birthday party with my son, and I wore humongous red sweatpants because I had my period. My sister said, ‘Are you actually wearing those out?’ I thought about it for a moment, but I still wore them. Who cares? They’re my period pants!”

2. She Improves Her Posture

Jones talked about her favorite workouts to Shape. She says that she does things that improve her 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. Two or three years ago I started doing barre classes, and after that I took regular private Pilates lessons. Then a friend told me about Lagree Pilates. 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 naked.”

3. She Does Workouts She Enjoys

For Jones, working out has to be enjoyable. She tells Shape that she sticks with Lagree Pilates because she enjoys it. “Lagree is quite difficult, but I’ve found that it’s the only thing that really makes me feel stronger, and I’m loving it. The music is good and there’s always a different routine, so it doesn’t get boring.”

4. She Goes To Classes

Jones likes to go to Lagree Pilates classes. She tells Shape that going to classes helps her stay motivated. “There are 10 of us in the class, and I like having women on both sides of me to push me,” Jones explained. “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.”

5. She Does At-Home Skincare

Jones has amazing skin, and she shared some of her tips to Into The Gloss. She says that she likes to do at-home skincare routines. “I like to take 20 minutes to lay in the bath, with a mask in my hair and a mask on my face,” Jones says. “I think I started really caring about my skin when I was modeling, just because we have to wear so much makeup. I don't get facials professionally done, either—I like to do them at home. I find something very calming and therapeutic about treatments at home.”
