A "plié" is a fundamental ballet movement that involves bending the knees while keeping the feet flat on the ground. This exercise is essential for developing strength and flexibility in the legs and is often performed at the beginning of ballet classes. There are two main types of pliés: demi-plié, which is a half bend, and grand plié, which is a full bend that allows the heels to lift off the floor. Pliés help dancers maintain proper alignment and balance, making them crucial for executing more complex movements. They also serve as a warm-up to prepare the body for the physical demands of ballet. Practicing pliés regularly can enhance a dancer's technique and overall performance.
