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 revealed.

2. Do Fast

While Jessie doesn’t explicitly call her fasting method intermittent fasting, she does fast for extended periods of time. She explained to Women’s Health that her diet closely resembles the 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. Do Eat Lots of Protein Rich

Jessie’s diet is protein rich. She might start the day with a bowl of oatmeal or toast and coffee with cream. Post-workout, she will sip on a protein shake. "For lunch, I will have 4 to 6 ounces chicken salad or chicken over rice," she revealed 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. Do Stock Your Kitchen with Healthy Food

Jessie keeps healthy frozen meals from Trader Joe's 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."

5. Don’t Skip Workouts

Jessie sticks to her workout schedule, even while on vacation. “Got in at 1:30 am last night from shooting a music video( deets on that coming soon)! But I wasn’t about to miss my work out! Gotta get it in!!! Here’s some snippets from this morning💪 (also if I’m in charge of the music and Eric doesn’t take over, I play @nickelback to get my hyped,” she captioned a recent post.

"The top of this year I decided to really step it up in the gym! Build more muscle, get my core in order and get stronger!" she wrote in a 2021 Instagram caption. "I know my core will probably never be as strong as it used to be but damn it I'm gonna try! I have goals and I'm not stopping until I'm there."

7. Do Try the South Beach Diet"My mom did South Beach when she was younger," the singer explained to E! News. "And I remember actually seeing the book at the house and that being a thing." In 2015, she opted to try the low-carb diet after welcoming her second child. "I just felt like, 'Okay, if Mom did it and we're the same, this will work for me. And I think what I liked about it was that it was heavy protein—we all know I love my protein—low carb and I just felt like I was already living like that,” she continued. "I felt like I saw results instantly. I got on the program and I worked out and it was just like, okay."
