Abstract
To satisfy one or more of the foregoing objectives, embodiments of a spring collar are provided for removably securing a disc weight to the sleeve of a barbell. In one embodiment, the spring collar includes a resilient wire form having a permanent magnet mounted thereto. The spring collar includes a coiled body having a central aperture, and first and second radial arms extending from the coiled body. The first and second radial arms can be moved toward one another to increase the diameter of the central aperture and permit a user to slide the coiled body over the sleeve. The permanent magnet enables a user to removably secure the spring collar to a ferromagnetic surface when the spring collar is not in use.
