Jessica Simpson's personal trainer has revealed how she lost a staggering 45kg after giving birth to her third child six months ago.
Harley Pasternak says the mum's transformation is down to a new "holistic post-baby lifestyle," and that she only worked out for 45 minutes a day.
"My mantra is
you get lean in life, and strong in the gym. So the majority of the weight loss actually came from everything she did outside of the gym, and then everything in the gym is about toning and tightening," he told People.
"The difference between this and the other times was that she worked out, yes, but her transformation was more about what she did on her own time."
