Abstract:
1. A system for exercising, comprising: a rotatable shell having an inner riding surface and an enclosed chamber defined at least in part by the inner riding surface, the enclosed chamber being dimensioned to receive a user that rides equipment along the inner riding surface; a frame that movably supports the shell such that the shell is rotatable about a first axis of rotation that extends through the shell; a drive system adapted to cause rotation of the shell about the first axis of rotation independent of a user's movement in the chamber, the drive system is configured to rotate the shell at a sufficient speed to simulate traveling down a slope as the user rides non-motorized equipment that travels along the inner riding surface; a controller communicatively coupled to the drive system, the controller is positioned outside of the rotatable shell and is inaccessible to the user riding the non-motorized equipment along the inner riding surface such that an operator positioned outside of the rotatable shell is capable of using the controller to command the drive system to adjust the rotational speed and orientation of the first axis of rotation, the controller including a first gravity sport program and a second gravity sport program, the controller being configured to selectively execute the first gravity sport program to command the drive system to rotate the shell about the first axis of rotation at a first speed to cause a first rider to travel along the inner riding surface towards a bottom of the shell such that the first rider is positioned at a first height to simulate traveling down a shallow hill, the controller being configured to selectively execute the second gravity sport program to command the drive system to rotate the shell about the first axis of rotation at a second speed to cause a second rider to travel along the inner riding surface towards the bottom of the shell such that the second rider is at a second height, the second height being greater than the first height; and a second axis of rotation about which the frame and the shell rotate and the second axis of rotation is spaced apart from the shell.
