An exercise device includes a cylindrical housing closed at one end and having a spring arranged therein. A plunger is connected with the housing and abuts against the spring. The plunger is adapted to reciprocate within the housing against the force of the spring. More particularly, the plunger includes a handle exterior of the housing which is grasped by the user. The closed end of the housing includes a pad which is placed against the chest of the user. The user grips the handle and displaces the plunger against the force of the spring to exercise the biceps muscle.
