What is a Plie? A plie is a movement in which a dancer bends the knees and straightens them again, with the feet turned out and heels firmly on the ground. It should be a graceful movement that shows no body movement. The only movement should be the bend in the knees. The body should remain centered and straight with the stomach pulled back to the spine and bottom pulled in.
In a plie the knees should bend over the toes with the thighs being pushed out. Heels need to be on the ground with your posture centered. Ensure hips are in line and head is up.
