A barbell collar apparatus features an elastomeric, flexible cylinder with a magnetic inner and an outer layer. Magnets are disposed adjacent to the inner layer, in various arrangement embodiments, to selectively secure the apparatus to a bar, typically disposed immediately adjacent to weights chosen, so that weights are retained against shifting and slippage along the bar. The apparatus is spread apart as needed for installation and removal from a bar. The apparatus is provided in pairs. The apparatus is provided in various colors to be easily identified and located. The light weight of the apparatus provides that additions to the weight and bar are negated in figuring the total weight lifted.
