Techniques for storing attributes of motion and sharing the motion are described. The motion of a first user is captured and analyzed, where the attributes of motion are stored on a server or cloud. The attributes of motion are represented in a 3D anatomical coordinate system to ensure a reliable representation of an anatomy behind the motion. When accessed by a second user, an avatar is animated per the stored attributes of motion while capturing similar motion made by the second user. A stream of showing the differences in the motion by the second user and the avatar is provided to a device associated with the second user.
