A tilting inversion exerciser includes a table rotatably supported on a supporting stand, a foot retaining device for being powered and actuated to clamp and to retain ankle portions of the user to the table without being operated manually by the user. A motorized coupling device may move and adjust the table relative to the stand. A safety device may be used for switching off the foot retaining device to prevent the ankle portions of the user from being disengaged from the foot retaining device inadvertently when the table is operated by the user, particularly when the table and the user are rotated to a vertical position relative to the supporting stand and the ground.
