Rond de jambe on the ground. An exercise at the bar or in the centre in which one leg is made to describe a series of circular movements on the ground. Both legs must be kept perfectly straight and all movement must come from the hip, along with the arching and relaxing of the instep. The toe of the working foot does not rise off the ground and does not pass beyond the fourth position front (fourth position ouvert) or the fourth position back. This is an exercise to turn the legs out from the hips, to loosen the hips and to keep the toe well back and heel forward. There are two kinds of ronds de jambe à terre: those done en dedans (inward) and those done en dehors (outward).
