“I work out and lift because I want to feel good and have energy. I want to enjoy the foods I love, like pasta and bread and chocolate chip cookies,” the “Flip My Hair” singer told Us Weekly. “I drink water all day long and I try not to eat past 6:30 p.m. I take probiotics and fiber on a daily basis.”

4. She Takes Fiber

“Americans should consume 28 grams of fiber per day if they're following a 2,000 calorie diet, according to the FDA,” says our sister site Eat This, Not That! “Unfortunately, we're getting nowhere close to that amount. A report from the Food and Drug Administration says that the average American woman eats only 15 grams of fiber a day, while the average adult man consumes just under 19 grams per day.” Try navy beans or acorn squash.

5. She Does Pushups and Planks

Decker and husband Eric Decker like to work their core. “This core-strength exercise is called the modified plank,” says the Mayo Clinic.

• “Lie on your stomach. Raise yourself up so that you're resting on your forearms and your knees. Align your head and neck with your back, and place your shoulders directly above your elbows. Tighten your abdominal muscles.
• Create resistance by pressing your elbows and your knees toward one another. Neither should move from their positions on the floor. Hold for three deep breaths.
• Return to the start position and repeat.”

Next up? Overhead squats with resistance bands, medicine ball slams and tosses, medicine ball chest passes, medicine ball sit-up tosses, resistance band pulls, deadlifts, step-down exercises, weighted overhead presses, inverted rows, bent over kettlebell rows, weight plate steering wheel exercises, dumbbell rotations, and box jumps. "I work out 3 to 4 times a week and they pretty much look like this with certain variations whether we're doing more upper body or lower body," she explained.

2. She Intermittently Fasts, Unofficially

Jessie is a fan of intermittent fasting, but she doesn’t call it that. She explained to Women’s Health that her eating method is very similar to a 16:8 fasting routine. "I eat what I want to eat within that time frame but don't overdo it," she explained. "The timing really is important to me."

3. Her Diet Is Protein Packed

In order to fuel her workouts, Jessie consumes a lot of protein. When she eats breakfast it will be a bowl of oatmeal or toast and coffee with cream. After her workout, she will sip on a protein shake. "For lunch, I will have 4 to 6 ounces chicken salad or chicken over rice," she explained on Instagram. "For dinner, I will either have a lean red meat, like flank steak with vegetables, chili from my book, or the same kind of thing—chicken and rice vegetables or my fit-enchiladas from my first book.”

4. She Loves Frozen Meals From Trader Joes

Jessie always keeps frozen meals from Trader Joes on hand. "They are so good if I don't have time to make myself lunch," she told Women’s Health. "I get the Indian curry or butter chicken and rice meals, and they are so delicious and filling. I have stashes of them in the freezer in the garage. I never want to run out."

Decker’s husband, Eric Decker, is a player in the NFL. You’d think that that means that they would do a lot of couple’s workouts together. However, you’d be wrong. In an interview with Taste of Country, Decker says that she avoids working out with her husband. “We tried, but he annoys me when he works out,” she explains. “He thinks he knows everything. I feel like, whatever I’m doing, it works for me.”

2. She Sets Goals

I have goals and I’m not stopping until I’m there.”

In the same Instagram post, Decker revealed that the most important part of fitness and wellness for her was not working out. She says that she puts more thought and effort into her daily diet, and tries to watch what she eats. “The biggest factor is watching what I EAT and making sure whatever I’m putting in my body is going to make me feel strong and energized.”

5. She Believes In Moderation

Decker tells Women’s Health that she keeps her diet pretty healthy. However, she does also believe in indulging at times, and keeps a balanced diet. “There are some weeks when I’m following more of a strict diet because I have something coming up,” she said. “But, you know, for the most part, I’m always enjoying food and I always say ‘everything in moderation’ on a day-to-day basis.”
