Jada Pinkett Smith may be 43 years old, but she doesn’t look it for a minute–especially when the view is of her bikini-clad body rocking killer curves on a beach in Hawaii. Jada was vacationing with hubby Will Smith, along with son Jaden and daughter Willow, just after the holidays.

Appearing on the cover February’s issue of Shape magazine, Pinkett Smith shares within its pages just how hard it is keeping that incredible shape at her age–and she admits it’s not nearly as easy as it used to be.

“My energy levels just aren’t the same,” she said. “My joints, my knees, the amount of weight that I can push versus what I did in my twenties, how long I’m willing to work out. For example, I’m not staying at the gym for two hours anymore. I hit it and quit it…I’m not going to stress my body that way any more. I can’t.”

“The No. 1 reason I go to the gym is because it keeps me sane. It gives me a place to exert energy, frustration, sadness, happiness, and joy. I don’t go to the gym just to look good. I go because it also keeps my head straight,” she added.

Jada Pinkett Smith needs her sanity these days–especially as the mom to two teenagers. Daughter Willow Smith recently made news for posting a ‘topless’ photo on Instagram. Willow, of course, wasn’t topless, but instead was wearing a top that featured a sketch of a woman’s breasts and upper torso.

Might Jada Pinkett Smith and Will Smith suddenly find their hands full with Willow? She doesn’t seem to have done more than most teenagers do in that age of seeking to find their true selves. If that’s the worst they encounter (and chances are, it won’t be) then they’ve probably got it made. The fact that their lives are played out in the limelight doesn’t help, of course.

While in the throes of raising teens, Jada seems to have a pretty good idea on what she needs to do to keep herself both healthy and gorgeous. She credits hubby Will for keeping her motivated.

“Well, I love when Will looks at me and says, ‘You look so freaking good!’ When my husband of almost 20 years can’t take his eyes off of me? That’s amazing,” she said.

Do you think Will Smith realizes what he has? As the husband of Jada Pinkett Smith, he certainly appears from those on the outside looking in, like a very lucky man.
