Jessie doesn't mess around in the gym, doing lots of weight training. She recently shared an Instagram video of her routine. Her intense workouts begin with 30 seconds of jump rope, high-knee running, ankle grabs, high kicks, lunges and lateral lunges, spinal rotations, and tension squats. 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. df44d9eab23ea271ddde7545ae2c09ec

Jessie doesn't officially call her way of eating intermittent fasting, but she doesn't eat for long stretches of time. Her eating method is very similar to a 16:8 fasting routine, she told Women's Health. "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."

Jessie packs a lot of protein into her diet. If she does eat breakfast it will be 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." 

Jessie is a fan of frozen TV dinners, only she opts for the healthier versions from Trader Joes. "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."

Jessie doesn't let anything get in the way of her workouts. "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. Even during vacations she manages to get a workout in.
