1. A method of spatially projecting a trainer into a three-dimensional (3D) virtual space rendered in a virtual reality (VR) head-mounted display (HMD), comprising:
upon initiation of a VR session by a user located in a physical space, rendering a training video within the virtual space, the training video having been generated by recording a trainer in front of a chroma key background, wherein the training video is rendered in the virtual space with the chroma key removed and in association with one or more interaction events;
as the trainer in the training video actively participates in an interactive workout with the user, and responsive to a movement of the trainer within the training video and an associated audio cue, displaying an interaction element that represents a target location in the virtual space for a movement of the user, together with an associated interaction lighting cue that represents a guide for the user movement in the physical space with respect to the target location of the interaction element; and
upon receipt of data indicating that the user's movement in the physical space corresponds to the target location of the interaction element in the virtual space, updating a score indicator.
