The present invention relates to an exercise mechanism for muscle strength enhancement that is capable of using one or more of a pressurization exercise using a lower body and a hand, a twisting exercise using a hand, and a massage function based on vibration at the same time so that health can be maintained through muscle enhancement and blood circulation promotion, can be conveniently used by being stored nearby with a stand, and can provide decorative effects. The exercise mechanism for muscle strength enhancement according to the present invention includes: a pipe-shaped main body having upper and lower guide rods and multiple locking pieces where steps are formed at tips； a pair of coil springs providing an elastic force with respective ends in contact with both sides of a wall surface of the main body； and a pair of operation units respectively inserted into circumferential surfaces at both ends of the main body and then capable of moving in a horizontal direction and performing a rotary motion at the same time by the coil springs while a deviation is prevented by the locking piece. The operation unit is made up of a grip portion having an inside cover having a coupling hole formed at the center to be inserted into the circumferential surfaces at both ends of the main body and an outside cover screw-coupled with the inside cover and a guide bracket where a flange part is screw-coupled in the inside cover. Upper and lower arc-shaped guide grooves are formed in a wall surface of the guide bracket so that the guide rod of the main body is inserted and passed through. In this manner, a rotation angle of the grip portion is controlled. A plate spring is included so that a restoration force is provided during grip portion rotation.본 발명은 하체 및 손을 이용하는 가압운동과, 손을 이용하는 비틀림운동 그리고 진동을 통한 마시지 기능을 단일 또는 중복하여 사용할 수 있도록 하여 근육 강화 및 혈액순환 활성화를 통해 건강을 유지시키고, 스탠드를 이용하여 근접한 곳에 보관하여 손쉽게 사용할 수 있음은 물론 장식효과를 제공할 수 있도록 한 근력 강화용 운동기구를 개시한다.본 발명에 따른 근력 강화용 운동기구는 관 형태를 이루면서 상하부 가이드봉과 선단에
