AFTER gaining 28kg over the course of her second pregnancy, singer Ciara has revealed the intense workout plan that helped her get back her pre-baby body.

The 32-year-old told Cosmopolitan magazine she exercised three times a day, in between breastfeeding her baby daughter.

“It was kind of like, wake up in the morning, breastfeed, eat a small meal, go train, come back in, breastfeed, eat another meal, go train, then come back, have another meal, and then a third training session at night,” Ciara said.

“It was a good challenge — one I set for myself, not for anyone else. Taking care of myself makes me feel really good. And I want to keep it sexy too, you know.”

She has two children Sienna Princess, 1, and Future Zahir, 4, with husband Russell Wilson, an American football quarterback.

While she’s now slowed down her routine, she initially lost about 20kg in five months.

Ciara told People magazine she implemented the “craziest system” to shed the weight.

“I was even more fired up about getting my post-baby weight off (this time),” she said.

“It was just my own personal goal that I set for myself. It’s a whole different animal when you have two kids, and it felt really good.”

Through her pregnancies, she suffered from diastasis recti, a condition in which the large abdominal muscles separate, usually treated with exercise — so she boosted her core workouts.

“I have to work even harder. That’s a bit more intense,” she said. “A lot more effort goes into it because your muscles bulge out differently, and you’re trying to reconnect the muscles and retrain them.”

Ciara says she does let herself indulge every now and then to retain balance in her life.

“I’ve definitely been picking up more burgers and fries. Life is just so much better that way. I just do things in moderation,” she said.

“I honestly like some of the hips that have come along with the post-baby weight. I’m not trying to lose those. My husband has been showing me love on my hips, too. He likes them!”
