Abstract: Exercise apparatus comprises a mounting member in the form of a bar and weights for location at the ends of the mounting member. Each weight has a substantially planar base and a mounting channel above the centre of gravity of the weight. The bar has mounting portions of complementary non-circular cross section to the mounting channels in the weights. The coupling between the channels and the weights and the mounting portions of the bar are configured to prevent rotation of the weight on the bar, such that during exercises the centre of gravity of the weights remains below the bar. A rotatable grip portion is provided on the bar, to accommodate rotation of the grip of the lifter on the bar.
