The present invention relates to a rotation exercise device and, more particularly, to a portable rotation exercise device that is configured to be rotatable based on facing in a single shape such that its configuration can be simple and production cost can be significantly reduced and is capable of simultaneously providing a waist strengthening effect based on a waist twisting exercise and an acupressure effect based on an acupressure disc. The present invention includes: an upper disc having the shape of a disc and having a circumferential protruding portion protruding to an upper side along its circumference a lower disc having the shape of a disc and having a circumferential groove portion recessed to a lower side along its circumference a plurality of bearing balls placed in a space between a lower side of the circumferential protruding portion and the circumferential groove portion that is formed by the upper disc and the lower disc facing and being coupled with each other a fastening member allowing the upper disc and the lower disc to be coupled with each other in a state where the bearing balls are accommodated and the acupressure disc on an upper side of the upper disc where a part of a user&primes body is received. The fastening member is coupled with the acupressure disc through central portions of the upper disc and the lower disc. The acupressure disc and the upper disc are configured to be rotatable about the fastening member. The upper disc and the lower disc are configured to be placed to face each other in the same shape.COPYRIGHT KIPO 2017본 발명은 회전운동기구에 관한 것으로서 더욱 상세하게는 하나의 형상으로 마주하여 회전가능하도록 구성함에 따라 구성을 단순화하여 생산원가를 대폭 절감할 수 있음은 물론 휴대가능하도록 하며 허리 트위스트 운동을 통한 허리강화 효과와 지압원판을 통한 지압효과를 동시에 제공할 수 있는 회전운동기구에 관한 것이다. 이를 위해 본 발명은 원판형태로 형성되며 원주를 따라 상부측으로 돌출되는 원주돌부가 형성되는 상부원판과 원판형태로 형성되며 원주를 따라 하부측으로 함몰되는 원주홈부가 형성되는 하부원판과 상기 상부원판 및 상기 하부원판이 마주하여 결합됨에 따라 형성되는 원주돌부 하부측과 원주홈부 간 공간에 배치되는 복수개의 베어링볼과 상기 상부원판과 하부원판이 베어링볼을 수용한 상태로 결합되도록 하는 체결부재 및 상기 상부원판의 상부측에는 사용자의 신
