Rihanna's personal trainer reveals how Esquire magazine's "Sexiest Woman Alive" gets her smokin'-hot body stage-ready.
Celebrity fitness trainer Ary Nuñez, who has worked with Rihanna for four years, told the US' Shape that Rihanna's workouts, which have to be squeezed into her hectic schedule, consist of a mix of martial arts, dancing, and calisthenics.
And the singer's rock-hard abs? Nuñez said they focus on the core muscles, with exercises like sit-ups, rotations and planks, and do lots of repetitions.
Rihanna's diet is also carefully crafted, with Nuñez advocating the food combining diet. "You shouldn't mix starches with protein because there is an enzyme that exists for the processing of starches, and an enzyme that exists for the processing of protein and they don't get along," Nuñez says.
A typical meal for Rihanna consists of "fish with a salad or veggies," said Nuñez.
How to get Rihanna's body
Weight-loss coach Andrew Cate told Health & Wellbeing that there was no scientific evidence food combining works. "Most foods contain a combination of carbohydrates, protein and fat, and these nutrients are not designed to be separated," he said.
"Your body secretes a variety of digestive enzymes that are more than capable of breaking down any food, or combination of ingredients."
A healthier, far less complex option, is the DASH diet, which was named the "best diet overall" by U.S. News & World.
