Jessica Biel Pregnancy Chatter

This could easily be a reference to the singer's first child, Silas, who was born last April. The boy's mom is Timberlake's wife, Jessica Biel.

In fact, Biel has managed to get her athletic figure back just four months after giving birth. In a recent post from E! News, the actress's personal trainer Jason Walsh opened up on an exercise activity called the VersaClimber, which is perfect for all new moms.

"Anyone can do it," Walsh said. "The great thing about the VersaClimber is it's super safe. It's a natural motion; it's a crawling motion. We're all born with it. It's low-impact. It reinforces proper movement patterns. It's the upper and lower body. It's huge cardio or conditioning impact. Metabolically speaking, it incinerates calories more than anything else out there."

The trainer attended the opening of new fitness studio Rise Nation in West Hollywood where women with babies can achieve the body they desire.

"Mothers, after having the kid, they really need to pay attention to the breastfeeding and stuff like that. She can't really lose everything 'cause she is breastfeeding," Walsh said. "It's going to take a while. At least here, we aren't doing too much. She can kind of go at her own pace and it's fantastic."
