Abstract: A personal exercise device comprising a hoop-form tube containing ball weights for circulation, a handlebar cross-bridge spanning the tube diametrically and formed by a pair of bars extending side-by-side in spaced-apart, parallel relation across the tube. Pairs of elongate hand-grips are mounted transversely on the cross-bars such that the hand-grips can be grasped to orbit the device overhead to inevitably train core muscles of the trunk/torso when training muscles of the body extremities such as the arms and shoulders. The hand-grips can be parallel for exercising core muscles on opposite sides of the boy evenly; divergent for a semi-supinated grip; or convergent for a semi-pronated grip. Alternative handlebars are a single, zig-zag bar with hand grips on successive straight portions; a circular/wheel with hand-grips at intervals, mounted concentrically within the hoop by resilient supports bridging the hoop and handlebar; two arcuate bars spanning the hoop with hand-grips at intervals.
