Katy Perry's personal trainer has revealed his client loves to skip as part of her 25-minute work-outs, which she does five times a week.
Katy Perry keeps fit by skipping.
The 26-year-old singer enjoys five 25-minute workouts every week with personal trainer Harley Pasternak, who says her brief workouts are better for keeping her trim in the long term.
Harley said: "It's an intense workout that lasts 25 minutes. Working out more often for shorter periods is better than three times a week for longer.
"Katy loves jumping rope, so that's what we do for cardio. It's convenient, dance-like and expressive and efficient, time-wise."
Harley has also put Katy on a strict diet, where she eats five small meals a day, though once a week she can indulge in her favourite treats such as pizza and chocolate.
Harley explained: "She eats two meals and three snacks a day, consisting of healthy fats, lean protein, fibre and a non-sugar drink.
"Her favourite meal from recipes I've created is French toast - slices of bread dipped in egg white, skimmed milk and a little sugar, grilled and topped with low-fat ricotta cheese and berries."
