An exercise apparatus for providing resistance to a motion of a user. The apparatus is provided with a bar having a pair of buoyancy chambers which causes the bar to float. A user may exercise by submersing the apparatus in a body of water against a buoyant force provided by the chambers. An anchoring system for both the user and the apparatus is provided to secure a position thereof in the body of water. In addition, the chambers may be inflated by a pressurized gas canister contained within the bar. The buoyancy chambers are retained between collars and circumferential journals on the bar. Pivotally openable clasps engage the journals. Cylindrical retainers are positioned over the clasps to prevent the clasps from opening, thus retaining the buoyancy chambers on the bar.
