Callisthenics is a form of exercise consisting of a variety of movements which exercise large muscle groups, such as running, standing, grasping, pushing, etc. These exercises are often performed rhythmically and with minimal equipment, as body weight exercises.  Consciousness is being present in whatever you do.
