An exercise device for conducting push and pull type exercises includes a non-track slippery member for being moved toward and away from a stationery member. A spring biasing member may bias the slipper member toward the stationery member, and may couple the members together when the members are superposed together to form a compact case structure. The spring biasing member preferably includes an endless loop structure received in grooves of the members. The stationery member has one or more anti-slip pads, and the slippery member has a slippery layer.
