1. She Does Pilates

Pilates is January’s go-to workout. "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," she told Shape in February 2020. "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."

2. She Also Does Yoga

January also loves to do yoga. She trains with Kirschen, a private yoga instructor based in Los Angeles, and regularly shares photos of their sessions together. “Whether you’re a couch potato or a professional athlete, size and fitness levels do not matter because there are modifications for every yoga pose and beginner classes in every style,” explains Natalie Nevins, DO, a board-certified osteopathic family physician and certified Kundalini Yoga instructor in Hollywood, California to the American Osteopathic Association. “The idea is to explore your limits, not strive for some pretzel-like perfection. It is a great way to get in tune with your body and your inner self.”​

January is all about exercise classes because “music is good” and the routine changes so “it doesn’t get boring.” She added to Shape: “I like having women on both sides of me to push me. 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. Her Diet Is Healthy, Organic, and Balanced

“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. “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. She also loves to cook and might make salmon with french fries or pasta for herself and son, Xander. “We try to have lots of green veggies,” she added. One way she gets her greens in? “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 also eats organic. “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.”

5. She Does Cardio Barre

January told InStyle that she likes Cardio Barre, a combination of traditional barre moves with non-stop movements. “I feel better. I feel stronger. It’s muscle, obviously. I gained weight, but I feel tighter and more energetic, and exercising is legit,” she explained.
