She is one hot mama! Janet Jackson clearly took no time at all to shed every pound she gained during her first pregnancy. The mother-of-one’s weight loss has now hit 70 lbs, and her trainer explained how she did it. (Spoiler alert: no cardio!)

“I started training her about six weeks after she had Eissa so about March we started,” explained trainer Paulette Sybliss to E! News. “We had a very vigorous training schedule. We were training a minimum of four times a week and the sessions were never less than 45 minutes, no more than an hour. Very intense, though. Very intense training.”

“We were doing three or four exercises with weights back to back,” said Paulette. “What that does—you would look at her and think she’d done like an hour of cardio with me—but when you’re working with weights and you’re working the muscle that way, it elevates the heart rate, but also it’s creating that fat burning affect both during the session and also when she left me, and that was key.”

We noticed Janet’s massive weight loss in October, when she stepped out on a red carpet looking better than ever! Even Paulette was happy with the progress. “You can see how she looks. I mean her waist is tiny. She looks incredible and she’s so fit, but she’s also healthy,” she said. Watch the video below to see Janet’s tiny frame.

Though the 51-year-old is probably still getting over her split from Wissam Al Mana — filing for divorce just months after they welcomed their first child together — it seems that the mother-of-one is trying to take good care of herself. And since her triumphant return to performing, she’s definitely been looking like her old self again. But it hasn’t always been easy.

Shortly after her separation, reports surfaced detailing Janet’s unhappiness in her five-year marriage. “Janet felt like she couldn’t be herself anymore,” a source told Us Weekly, mainly referring to the cultural differences between the duo as Wissam is Muslim. “The restrictions flowed into her career as well. Though she canceled her Unbreakable World Tour in April 2016 to focus on her pregnancy, Janet felt like her music was suffering and she resented Wissam. She couldn’t settle down and be what he wanted.” 

Well, we’re happy to see that Janet is bouncing back from her devastating breakup. And we think she looks better than ever. You go, girl!
