The fitness bar is cylindrical, with a central through hole in the axial direction, and convex points evenly distributed on the surface. CN2117178U discloses a fitness stick, the surface of the stick is covered with a plurality of conical convex teeth, and the tops of the convex teeth are smooth. CN201098501Y discloses a fitness stick, which includes a stick body and an elastic band. The two ends of the stick body are fitted with telescopic rods and are fixed by telescopic sleeves; The elastic belt is composed of an elastic rope and a connecting belt. The connecting belt is divided into three rings: upper, middle and lower. The middle ring is set on the end cap, the lower ring is equipped with a gasket, and the upper ring is an empty ring; A resistance ball is arranged inside, and the two ends of the elastic rope are set in the lower ring of the connecting belt through a washer. These above technologies do not provide specific guidance schemes for how to make the fitness stick simple in structure and improve the use effect.

The axial directions of the three rod segments are distributed in a spiral manner, the helixes of the above-mentioned plurality of first protrusions are opposite to the helixes of the above-mentioned third protrusions, and the second rod segment A plurality of second protrusions distributed at intervals are arranged on the circumferential surface of the.

In the above technical solution, the length of the rod is preferably 45-55 cm, and the diameter of the rod is preferably 3-4 cm. The diameter of the second rod segment is preferably 1/2 of the diameter of the first rod segment, and the length of the second rod segment is preferably 1/2 of the length of the first rod segment. The shape of each first protrusion, each second protrusion, and each third protrusion is preferably a spherical crown, and their sizes are preferably equal.

The rod body described in the utility model has a first rod body segment, a second rod body segment, and a third rod body segment, and a plurality of first protrusions distributed at intervals are arranged on the circumferential surface of the first rod body segment. The first protrusions are distributed in a spiral manner along the axial direction of the first rod segment, and the circumferential surface of the third rod segment is provided with a plurality of third protrusions distributed at intervals, and these third protrusions are distributed along the third The axial direction of the rod segment is distributed in a spiral form, the helix of the above-mentioned plurality of first protrusions is opposite to the helix of the above-mentioned third protrusions, and the direction of the helix of the second rod segment is A plurality of second protrusions distributed at intervals are arranged on the circumferential surface. In this way, it can run and roll on the palms, soles and other parts of the body to achieve massage and fitness. The rod body can also be used for massage and fitness by rolling the rod body back and forth; at the same time, it is simple in structure, economical and practical, low in cost, convenient to use, and good in use effect (good effect in curing chronic diseases). It can be used not only for the rehabilitation of patients with chronic diseases, but also for massage and fitness for teenagers, middle-aged and elderly people.
