Abstract
Apparatus for improved alignment of the components of a freeweight barbell system include a weight tray employing spacing members for lateral support of the weights when stored upright thereon. The bar includes sleeves having shoulders to further align the weights when mounted on the bar. Guide channels include rearward downwardly disposed ramps to minimize contact of the weights with the tray surface until the bar has been moved to the rearward position. Interior weight support channels minimize bending of a weighted bar to ease movement and prevent lateral misalignment of the weights. Two alternate retaining clips are provided to improve the securing of the weights which themselves have been reformed to also improve support, guidance and alignment of the weights whether stored or secured to the bar.
