A "tendu" is a fundamental ballet movement where a dancer extends one leg straight out from the body while keeping the toes pointed. The foot glides along the floor, maintaining contact until the toes reach a fully extended position. This exercise helps develop strength, flexibility, and control in the legs and feet, which are essential for more complex ballet movements. Tendus are often practiced at the barre during ballet classes as part of a warm-up routine. They can be performed in various directions, including front, side, and back, allowing dancers to work on their alignment and balance. This movement is crucial for building the foundation of many other ballet techniques, such as pliés and jetés.
