Britney’s getting ready to go on tour this summer.

Ya betta work, Brit!

Britney Spears is keeping her toned body tight and wants her fans to know it. In a new Instagram clip, the 36-year-old pop star shared some footage from her workout.

Wearing a yellow sports bra and blue striped short shorts, Britney lifts weights and does some aerobic stretching, keeping a brisk pace while going through the routine.

Her hard work clearly paid off! Britney later shared a shot of herself in a form-fitted white off-the-shoulder dress.

The “Stronger” singer also shared a throwback photo of herself in a bikini top and tiny white shots, showing off her impressive abs.

Britney is staying in shape for her summer tour across North America and Europe. The concerts will feature her Piece of Me show from her Las Vegas residency and run from July 12 through Aug. 24.

"She misses a routine and wants to have one," a source previously told ET of the tour. "She will be touring places she hasn’t toured in years and loves to go visit, so that was also appealing to her."
