Sculpt a ballerina bod with Natalie Portman's ballet instructor.

Natalie Portman's performance in Black Swan landed her an Oscar. But her body transformation won our endless fascination.

With swimsuit season fast approaching, we went straight to the super-fit source: Portman's ballet instructor, Mary Helen Bowers, founder of Ballet Beautiful. Bowers, a former pro ballerina, created the workout to help everyone achieve long, lean and graceful lines. There's no barre or previous dance experience required. Trust us--we have two left feet and could still follow along. The next day, we were sore in places we'd never felt before.

Vital Juice readers can experience the exclusive workout here. Do it three times a week to remake your shape.

This workout's en pointe.
