Kelly Rowland has revealed the answer for the question in everyone's minds: how did she gain back her fit and fabulous figure just weeks after giving birth?

Just seven weeks after welcoming her first child with husband Tim Weatherspoon, the Destiny's Child singer showed off her amazing post-baby body while out shopping in Beverly Hills.

So what's her secret? A combination of intense workout routines and strict dieting, according to Rowland and her fitness trainer Jeanette Jenkins.

Jenkins shared the fitness routine Rowland underwent to gain back her pre-baby body in her blog, in which the fitness guru says she is "bringing you 6 weeks of workouts, motivation, nutrition and healthy living tips to help you reach your 2015 health and fitness goals!"

The workout plan is actually quite simple and has already proven to be very effective by Rowland; however, this plan isn't for the lazy ones.

To lose weight within the given time frame, Jenkins recommends preparing meals at home that should include plenty of green tea, water and at least three servings of green vegetables, TV3 noted.

For the workout, Jenkins had Rowland rotating between five fitness DVDs including "Bikini Bootcamp," "Cardio Kickboxing" and "Power Yoga."

Another thing that helped Rowland go through her gruelling fitness regimen was constant support and motivation from her trainer.

"I'm not telling you it's going to be easy," one quote reads. "I'm telling you it's going to be worth it!"

While being a hands-on mom remains Rowland's number one priority, the singer knows a healthy lifestyle can provide more benefits than you could never imagine.

"Getting started can be the hardest part of your journey to a healthier, happier you," Rowland and Jenkins wrote online. "But don't worry, we've got your back." So, who's ready to break a sweat?

The "X Factor" judge gave birth to baby boy Titan Jewell Weatherspoon on Nov. 4 and the singer hasn't stopped gushing about her first baby since then.

"My only sunshine," the 33-year-old mom wrote, along with a photo of her cradling her newborn. "You make my happy, when skies are grey #TITAN #LIFE."
