Rihanna gyms in bikini and tweets it

While most people prefer dressing down when they hit the gym, sporting loose tracksuit bottoms and T-shirt to be the most comfortable while exercising, Rihanna hit the gym in a tiny two piece.

The singer opted for something slightly more daring in Hawaii on Wednesday, sharing a picture of herself on her Twitter page wearing just a tiny white bikini as she posed on a cross trainer.

The 23-year-old teamed the triangle two-piece with a pair of huge sunglasses, and tweeted the shot with the caption: Haha, come tap this @Khloekardashian!!!’ the Daily Mail reported.

Rihanna later posted a series of other shots showing her messing around with friends while wearing the sexy two-piece. One showed her blowing a kiss to the camera while displaying her curves, while she laid on her front for another picture.

And when someone on Twitter asked her what the secrets to her incredible figure are, she replied: “Angles/Lighting/Photoshop :)”
