According to an embodiment of the invention, a casual exercise device includes a pedal movably attached to a base by a hinge at the base of the pedal. The base may be configured to lie flat on a floor or the ground, and force may be exerted to elevate the edge of the pedal distal from the hinge, such as by a spring incorporated into the hinge. This force may also resist a user's pushing down on the pedal. A counter may count the number of times the user taps the pedal, where a tap includes the user's pressing the pedal to the base, or within a specified angle or distance of the base, and then allows the pedal to rise again past a predetermined point.
