  • Patent number: 10118065
    Abstract: A spacer that is preferably made from high density polyethylene and has a diameter that is larger than a standard plate for a barbell. The spacer has a central hole dimensioned to accept a standard barbell and, when placed onto a barbell, will space the barbell apart from the ground a sufficient distance that a user can easily add or more plates from the barbell without having the lift the barbell. The spacer provides a more efficient way to add or remove weights from a barbell that is on the ground (e.g., when a user is performing deadlifts, snatches, and power cleans, etc.). The spacer may be placed on a barbell similarly to a regular weight plate, preferably before any other weight is added.
