The invention relates to a weightlifting device comprising a longitudinally extending bar, the bar comprising at least one weight bearing section adapted for accommodating one or more free weights comprising an opening adapted for surrounding the weight bearings section. The weight bearing section comprises an end stop for the one or more free weights at a first end of the weight bearing section, a recess at or adjacent to a second opposite end of the weight bearing section and a free weight locking member for locking the free weights and for preventing the free weights from unintentionally falling off from the second end. The free weight locking member is movable in a longitudinal direction of the weight bearing section between the recess and at least one free weight locking position located between the recess and the end stop. The free weight locking member is further movable in a second direction at the recess between an immersed position and an elevated position, the immersed position being a position where the free weight locking member is completely, or at least mainly, immersed into the recess, and the elevated position being a position where the free weight locking member is elevated with respect to the immersed position and extends at least partly outside the recess.
