Personal Trainer

Katharine takes the help from personal trainer Oscar Smith. She does a lot of hard work while working out. Her trainer always tries to do changes in the exercises. Oscar focuses on variation. If an exercise works or not, don’t stick with it just make variations in it. McPhee does gymnastics, surfing, Muay Thai and weight training too.

Oscar works with McPhee three to five times in a week in New York, averaging 1 hour in a day. According to Oscar, it’s 50 percent exercise and 50 percent diet. And, typically, an individual will definitely see some results in 2-3 months of following his advice. If he/ she doesn’t, then they are doing it the wrong way.

Talking about the diet, McPhee is not a vegetarian. She eats lean chicken, fish, a lot of veggies, nuts, fruits. She tries not to eat too many carbs.
