Abstract
Abstract Spring-loaded platform provides a workload for jogging in place. The platform is attached to an upright post and to a counter positioned in the post at visible level. The counter only operates upon a predetermined jog stroke length. The post is foldable and the platform pivotable into a handy carrying case. A horizontally positioned diaphragm provides a limit stop for the platform.
