A body roller apparatus is provided which enables therapy routines to be performed on various body muscle groups. A frame structure is part of the apparatus and comprises a base frame with a generally horizontal user support member having an opening being mounted thereon. The upper end of a roller structure rotatably supports a spherical roller, while its lower end mounts to the base frame so that at least a portion of the spherical roller extends through the opening of the user support member. The user operates the apparatus by positioning themselves upon the user support member and engaging with their body the portion of the spherical roller which extends through the opening. The vertical position of the spherical roller may be adjusted, and the frame structure itself may be collapseable for storage.
