Looking for some celebrity inspiration to up the intensity in the gym? Look no further: It's Britney, bitch.

In a recent Instagram video, Britney Spears gave fans a peek at the new workout routine she's using to prepare for her upcoming "Piece of Me" tour. The workout looks like a sweaty, full-body burner — and we wouldn't expect anything less from Britney.

The 36-year-old singer appears to be hitting her whole body, with a focus on glutes and core — and honestly, who doesn't love a good glute and core workout?

Spears works her glutes with jump squats, kettlebell swings, and a variety of donkey kicks and leg extensions. By including different types of donkey kick variations — including the traditional table-top donkey kicks and standing resistance band donkey kicks — she's working those muscles in slightly different ways, making for a more inclusive glute workout.

If it's not evident enough by Spears' impressive physique, she's a big fan of core work. In this video, she includes single arm/leg BOSU crunches and yoga abs.

She can even nail a backflip:

There's no doubt the pop star will be more than ready to take on her upcoming tour, looking fit as ever. And the next time you hit the gym, remember what Britney would say: You better work.
