Carrie Underwood was rounder when she was a contestant on American Idol.

But these days the 37-year-old Cry Pretty crooner has said she will not let her body look like that again as she relies on daily workouts and healthy eating to keep her lean, as she stated in her book Find Your Path.

On Wednesday her personal trainer Eve Overland added to that as she talked to UsWeekly about how the Grammy winning artist is so dedicated to staying fit that she will even run in place when doing her laundry.

And her top workout is running.

'When she hops on the treadmill or takes a jog outside in the sunshine, it dials in her mind,' said Eve.

And Eve has a gentle approach: 'My philosophy is: Do what you can when you can, and don't beat yourself up.'
