Abstract
A weight lifting bar has a plurality of hand grip portions rotatably mounted relative to the bar to include an outer ring fixedly mounted to the bar, with the outer ring diametrically aligned relative to the bar, with an inner ring rotatably mounted relative to the outer ring capturing a layer of bearings between the outer ring and the inner ring. A modification of the invention includes a hand grip bar mounted within the inner ring apertured to direct powder rosin therethrough to enhance grasping of the bar during use.

- a central bar, the central bar including a first distal end spaced from a second distal end, the first distal end including a first collar mounted adjacent the first distal end, with the second distal end including a second collar mounted adjacent the second distal end, and
- the central bar including a first and second outer ring fixedly mounted to the central bar between the first collar and the second collar, wherein the first outer ring and the second outer ring are mounted and secured to the central bar, and
- each outer ring includes an inner ring rotatably and freely mounted concentrically oriented relative to and within the respective first and second outer ring, and
- a plurality of individual bearing members mounted between each outer ring and each inner ring, and
- each inner ring includes a bar diametrically mounted fixedly within each inner ring, and
- each bar includes a first semi-cylindrical tube fixedly mounted within each inner ring, and each first semi-cylindrical tube includes a second semi-cylindrical tube hingedly and pivotally mounted relative to the first semi-cylindrical tube, and a porous bag member received between the first semi-cylindrical tube and the second semi-cylindrical tube, and the first semi-cylindrical tube and the second semi-cylindrical tube including a matrix of apertures directed therethrough, and powder resin contained within the porous bag.
