A weight training assembly includes a frame includes a first rail to which a slide member and multiple weights are connected. The slide member has a main rod with multiple through hole. Each weight has a transverse holes and longitudinal holes, each transverse hole has a pin received therein, and each longitudinal hole has a push rod received therein. A first spring is located between the pin and the weight. A second spring is located between the push rod and the weight. A push unit includes a push member which is located corresponding to the front sides of the weights. When the push member pushes the push rod from the first position to the second position, the pin moves from the third position to the third position and extends through one through hole to lock the weight to the main rod.
