A stretching exerciser includes an elongated base with an upright prop. The prop has a top end formed with a forwardly extending limiting projection. A seat member is mounted on the base. A connector includes a horizontal lever portion with a front end, a rear end which is mounted pivotally on the top end of the prop, and a bottom side which abuts against the limiting projection on the prop when the connector pivots forwardly. The connector further includes a vertical lever portion and a pair of curved connecting plates. A backrest member includes an elongated connecting frame unit with a bottom end that is mounted pivotally to the connecting plates. The frame unit is provided with a limit plate, and the connecting plates abut against the limit plate to limit rearward pivoting movement of the backrest member relative to the base. A resistance cylinder is connected pivotally to the vertical lever portion of the connector and to the connecting frame unit of the backrest member to resist forward pivoting movement of the backrest member relative to the base. A handle unit is secured to a top end of the backrest member. A biasing unit interconnects the base and the connector to resist rearward pivoting movement of the backrest member.
