How did Britney get back in shape? A lot of hard work, the pop star says.

“I have had to work hard at getting [my body] back to where it used to be,” Spears tells Glamour in its January issue. “I used to be obsessed with working out … But I can’t get motivated right now because I’m so focused on my music.”

What about her workout regimen?

“It isn’t fun [for me], so to do it every day would be horrible,” Spears say of going to the gym. “Three days a week is cool, even two. It makes me feel good and feel like I’ve done something. It’s important to take care of your body.”

Still, Spears, who will turns 27 tomorrow, says that with her efforts comes a new appreciation for her body. “Recently I started to appreciate my body a bit more from before I had kids,” the singer says. “But it completely changed.”
