Rihanna's workout The secrets behind that body
The 23-year-old singing legend is kept to a strict regime where she has to work out at least three times a week for a minimum of 25 minutes.
Her personal trainer Harley Pasternak has revealed to the Daily Mail that her usual work out regime involves a combination of cardio techniques - including skipping, cycling, jogging and jumping jacks.
As for her diet, apparently it's rich in protein, and beans. And rather than for three meals a day Rihanna opts for five mini meals a day to keep her metabolism working.
Almost sounds achievable for us mere mortals... minimum of three times a week? If Rihanna can achieve that body with a couple extra meals and a few jumping jacks then we're gonna give it a go...
Wonder how many jumping jacks it will take to look like her?
Her personal trainer told People.com: "She's got such a beautiful body naturally. With someone like her, it's about the fine tuning.
