Jessie James Decker in Workout Gear is "Ready to Get My Legs Going Again"

Jessie James Decker is back on the treadmill after baby! In a new social media post, the country singer revealed she is exercising again, less than one month after welcoming baby number four. "Starting off slow but decided to do an easy 20 min walk! Ready to get my legs going again," she captioned the Instagram Stories image of herself walking on the treadmill. How does the star shape up post pregnancies? Here is everything you need to know about how Jessie is getting her body back. 

In an Us Weekly interview she revealed how she lost her baby weight in 2019, starting with exercise. "I didn't start working out until three months post because I had C-sections and you can't work out for a really long time. So I started working out a little bit. I didn't really diet yet at three months because I was still making lots of milk and I wasn't ready for that. Started working out though," she said.

At four and a half months she started the South Beach Diet again. She started on phase two of the diet, "because I needed to have enough calories to produce milk," she said. "I just did that consistently. I really did. I followed it like crazy," she continued. "I did it from top to bottom. I did this diet 100 percent, literally a 100 percent, and it's the fastest I've ever lost weight. It just kind of melted off."

In another Us Weekly interview she dished on her diet. She starts her day with the South Beach Diet sausage English muffin sandwiches for breakfast. She also has a South Beach Diet lunch. "For dinners, I don't do the South Beach Diet meals. And that's the thing about South Beach, they don't want you to always rely on the meals. They want you to learn how to make these things yourself. Or when you're out at dinner, it's the South Beach way. So it's not necessarily, you have to only eat these meals that deliver to your house. It's like I'm learning the proportions and I'm learning what I can and cannot eat. So I might have South Beach breakfast and lunch, but for dinner I'm going to make something for my family that we all could eat. So it could be brown rice and chicken and veggies, or I'll make gumbo, which is actually very lean. Believe it or not. There's only 160 calories in a cup of gumbo."

As for exercise, "I really love high intensity, really quick, and I like heavy weights," she said. There is lots of research backing up the benefits of HIIT workouts, including body fat reduction, improved cardiovascular function, and mental health. It is also time effective. 

Jessie confessed that she hit her goal weight, and lost even more than that. However, she would rather be strong than skinny. "But I think I lost muscle and I'm not happy about it," she said. "So I need to lift, have some more South Beach protein shakes."
