An exercising and/or amusement device supported by a ground surface and on which a person may stand. The device includes a walking beam having first and second platforms at opposite ends thereof for supporting the feet of a person, each platform having an upper surface adapted to support one of the person's feet. A ground engaging element is associated with each platform. Each ground engaging element has a bottom surface for engaging a ground surface, a hemispherical supporting surface, and a pin extending from the hemispherical supporting surface. Each platform is pivotably connected to an associated ground engaging element by a pivotable connection including a curved concave bottom surface on each platform shaped complementary to the hemispherical supporting surface of the associated ground engaging element and having a slot therein through which the pin of the associated ground engaging element extends. A plurality of resilient members engages the pin and urges it toward a neutral position. The resilient members are oriented such that extension of at least one of the resilient members applies a restoring force to the pin along a longitudinal axis of the walking beam.
