Jessica Alba plans to work out for 45 minutes a day to get back in shape after giving birth.

The 'Fantastic Four' actress is eight months pregnant with her second child with husband Cash Warren, but is already planning how to get her figure back despite not being a fan of working out.

She told Lucky Magazine: "Working out every day for even just 45 minutes is good for my mental state.

"Getting dressed and actually doing it is the worst. It's hard to get motivated.

"In the gym, I have, like, five things to distract me: TV, iPod, magazines.

"Working partners are good, too, so you can chat and not just drown in your own misery. Sorry, does that sound bad? I just hate working out."

Jessica - who already has three-year-old daughter, Honor, with Cash - will also be keeping to a strict diet to lose her baby weight.

The 30-year-old beauty added: "I have a hard time with portion control, so I have 1,200 calorie meals delivered. But I also work out, so basically I'm starving-it sucks. I drink a lot of water."
