Abstract
This invention relates to an inertial force, accommodating resistance exercise device and method. The subject device includes a nonrotating structure of enhanced mass and at least one wheel connected to the nonrotating structure to permit the device to be rolled to enable a user to perform accommodating resistance exercise. The mass of the nonrotating structure may be varied according to the requirements of the exercise by substituting inertial disks of different size and/or an inertial cradle or cage member. In exercises utilizing the instant invention resistance is accommodating in direct proportion to the speed with which the mass of the nonrotating structure is translated and direction in which it is translated.
