Scherzinger loves to mix up her workouts to keep things interesting, and trains with Viking method instructor Svava Sigbertsdottir whenever she’s in the UK. “I love Svava’s technique,” Scherzinger says. “With me, she does a combination of her functional training, martial arts and ballet isolation exercises. In all my years of training, the Viking Method is unlike anything I have ever done.”

2. Oysters and Lemon

Scherzinger loves to eat fresh oysters, especially when she’s in New Orleans. “Yes, oysters are very good for you,” according to preventive cardiology dietitian Julia Zumpano, RD, LD. “In fact, you probably didn’t know that it’s hard to beat all the health benefits of oysters from a nutritional standpoint.”

3. She Loves To Surf

Scherzinger is a Hawaiian girl through and through, judging by her surfing skills. “Surfing can definitely be considered a form of interval training which combines short, high intensity bursts of speed with a recovery phase, repeated during exercise training,” says CSUSM professor Dr. Sean Newcomer.

4. She Snacks On Corn

Scherzinger loves to snack on corn on the cob with lots of butter. “Corn has many health benefits,” says Caitlin Terpstra, RD, LD. “It consists primarily of insoluble fiber, which makes it a low-glycemic index food. This means it is a food that is digested slowly and doesn't cause an unhealthy spike in blood sugar. It also contains many B vitamins, as well as essential minerals, including zinc, magnesium, copper, iron and manganese. Since corn is considered a starchy vegetable, people with diabetes need to keep in mind that a half cup of corn, or a small ear of corn, contains 15 grams of carbohydrate and counts as one carbohydrate food choice.”

5. She Works Out With Friends

Scherzinger loves to work out with her friends to stay motivated. "Me and my girlfriends support each other for the gym. Because, you know, it’s hard to be motivated sometimes, so when you go you push each other, we try to do different things. We’ll go hiking one day and then we’ll try a sculpting hot yoga class, then we’ll do cardio. We just motivate each other."
