<p>A weighted exercise apparatus 1 comprises a hollow body section 2 containing a flowable weighted material that is movable within the housing. The housing has a longitudinal axis A and longitudinally opposed end sections 6. A connection socket 16 is located at each end section. A pair of handle members 4 are provided corresponding to the connection sockets, each having a connection end sized and configured to be received within an open end of the corresponding connection socket. Each handle member includes at least one radially extending retractable locking pin (figure 4, 52) and a radially extending rigid projection (figure 4, 54). The corresponding socket includes a channel extending around part of the inner circumference for rotationally receiving the projection and at least one aperture configured to receive the at least one locking pin. The projection and at least one locking pin are arranged such that when the locking pin is aligned with and received within the aperture the projection is received and longitudinally restrained within circumferentially extending channel to provide a secure yet easily releasable means of rotationally locking the handle relative to socket. There is also disclosed a flowable weighted material, comprising spherical metal pellets and a lubricating oil, in the volume of 0.5ml to 1.5ml per 1kg of metal pellets.</p> |
