An adjustable-weight club exercise device is provided having improved safety, adjustability, and manufacturability. The club body includes multiple recesses designed to receive removable weights. The recesses are all accessible individually to insert or remove weights in a motion perpendicular to the longitudinal direction. The recesses are formed by ridges designed to secure the weights to prevent any movement in the longitudinal direction. The device may be operated with any or none of the recesses filled. A door and latch design are provided to allow access to the recesses and securely close the club body.
