Jessie James Decker is her best self these days. The country singer and reality TV star, who had her second child in 2015, admits she feels healthier and more content with her body than before having kids.

"I hate those unrealistic goals that people place on women. It’s just not right," Decker says.

"It took us nine months to have our babies and put on this weight," she tells Self magazine. "I gained 55 pounds with my daughter, so I get it, it’s tough. But you can't just pop out a baby and expect to be the size you were before, it just doesn't work like that."

Decker, who is married to the NFL's Eric Decker, has adopted a healthy lifestyle on her own time and has recently become a brand ambassador for the South Beach Diet.

"I relied on being young and my genetics and I just kind of stayed thin," she tells Self of her pre-baby body. Her daughter was born in early 2014, and her son followed in September 2015. "My body looks completely different than it did before kids. I feel like I have more energy now and I feel more proud of myself because I had two kids and know I really accomplished something."

The country singer says that she consciously shifted her focus to eating vegetables and eating "really clean and paying attention to nutrition." But Decker is trying to be as realistic as she can, working out a couple times a week. Whether it's running around with her kids or doing weighed circuit training she stresses the importance of creating easy-to-accomplish goals.

"I hate that people make women feel that’s what they have to do," she adds. "You can get to all that stuff later when it’s right for you."
