An abdominal exerciser device includes a self-standing casing that freely movably supports an exercising member such as a ball with an exposed surface protruding upward from the casing for contacting a user's body part. The device also includes a hollowed cover connecting to the casing to protect the exposed surface from outside environment when the device is unused, and a handgrip for hand-carrying the same. The device can include a carrier having an adjustment member mounted thereon to adjust position of the casing relative to the carrier.
