A hula hoop, comprising a hoop body which includes a plurality of unit sections connected end to end, two adjacent unit sections are detachably connected to each other through a connecting member, and each unit section has an accommodating groove for inserting the connecting member. The front section and the rear section of the connecting member are inserted into the accommodating grooves of two adjacent unit sections, and the unit section has a locking mechanism for keeping the connecting member in the accommodating groove. The hoop body comprises a plurality of unit sections connected end to end. Two adjacent unit sections are connected to each other through a connecting member, which can realize the rapid disassembhly and assembly of the unit sections. By increasing or reducing the number of unit sections, the inner diameter of the hoop body can be changed to adapt to exercisers with different body shapes, and the hoop body can be opened at any position, which is more convenient to operate than the prior art.

The present invention aims to provide portability and ease of storage and mobility by allowing housing when a hula-hoop is not in use and connection in a circular form by withdrawing when in use, so as to be utilized for exercise and play. The hula-hoop comprises: a main body capable of being divided into a plurality of parts having a circular cross-sectional shape and a two-dimensional arc shape; a plurality of middle bodies which are housed in and withdrawn from one side of the main body; and an end body housed or withdrawn by being coupled to the last middle body from among the middle bodies and which connects to the other side of the main body, wherein the main body, the middle bodies, and the end body are constituted so as to be housed and withdrawn in multi-steps as in the form of an antenna or a fishing rod.

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.
