Lucie Fink no stranger to tough jobs. She's challenged herself to snowboard, yoga, working out for 5 days in a row, and even testing out an anti-gravity treadmill! But none of those compare to her latest challenge: performing as a prima ballerina! Combining pure athleticism and spot-on artistic talent, the ballerina is one of the most versatile performers in showbiz — and a prima ballerina notably has the highest honor within the company. Their job: make it look easy. But let me tell you, being a ballerina is far from elementary. Even the warm up was challenging! Isabella Boylston, a principal dancer at the American Ballet Theatre, taught Lucie how to stretch, move, and look like a ballerina. Pro-tip: Grab yourself a ton of bobby pins!
