A dual action weightlifting machine has a stationary frame including a racking portion and spaced vertical guides slidably mounted on opposite sides of the frame for horizontal movement relative to the frame. A horizontally extending exercise bar assembly has spaced first and second vertical slides slidably mounted on the vertical guides, a user engaging portion for gripping by a user, at least one rack engaging portion having a smooth cylindrical surface which directly engages a selected support portion of the rack assembly in a racked position of the exercise bar assembly, and opposite first and second end portions for receiving one or more selected weights. The user engaging portion is located between the opposite sides of the frame and has a central longitudinal axis which is aligned and coaxial with the cylindrical surface of the rack engaging portion.
