This week belongs to Britney Spears: between her Circus album dropping (can we say new workout songs?) and her standing-ovation-worthy performances, we seem to be witnessing the pop star's long-awaited comeback. Britney worked hard getting back into world-tour shape, and she admitted to Glamour magazine that she thinks going to the gym "isn’t fun . . . so to do it every day would be horrible. 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."

Britney acknowledged dueling feelings toward her post-baby body and said, "Recently I started to appreciate my body a bit more from before I had kids. But it completely changed." Her rigorous dance practices and workouts with her trainer, Kacy Duke, are responsible for the pop star's toned physique. Duke was kind enough to share her professional advice for getting Britney's hot bod. To see some of her tips, read more.

• Booty call: Duke says, "You need to do something that pumps and elongates the muscles that work the buttocks, but also works the thighs, because they are connected."
