An apparatus and method is provided for quadrupedal exercise, i.e. exercise by walking or running on all fours in a manner similar to four-footed animals. The apparatus is composed essentially of a forward continuous tread and a rear continuous tread, in which the forward continuous tread is disposed at a higher level than the rear continuous tread, the relative heights of the two being adjusted so that when the hands of the user are placed upon the forward tread and the feet are placed on the rear tread, the angle of the body through the spine will be essentially horizontal, or a little greater than horizontal. In most cases, the tread for the hands or support of the upper portion of the body will be divided into two parallel treads while the tread for support of the feet will be a single tread positioned more or less in a central position with respect to the forward tread. A method of exercising involving movement relative to a two-level track is also disclosed.
