“It's interesting to work with celebrities; they are very goal-oriented. But they still have to put their shorts on one leg at a time.”

“I had a client who was getting ready for the Oscars, and all she ate was one meal a day - of two boiled eggs!

“Ideally, we should be controlling what we eat by cooking for ourselves.”

“Blueberries, strawberries, and broccoli are all high in vitamins.”

“Feeling your clothes fitting better is going to make you feel better.”

“January is the best time of year for gym owners. You all come. It's great! And then, by Valentine's Day, you're not coming in anymore.”

“Don't fool with machines you're not familiar with - stick with the treadmill and elliptical.”

“Avocado is one of my favourite fruits, and my daughters and I love avocado in salads, and even in smoothies.”

“The moment your kids start crawling, they are exercising. To them, movement is fun and organic... It is adults who have turned daily activity into a mandatory chore.”
