Landmine apparatuses
Landmine apparatuses include a mounting base and a receptacle for receiving a weight bar. The receptacle is coupled to the mounting base and rotatable about a horizontal axis and in 360 degrees about a vertical axis. A vertical pivot connects the receptacle to the mounting base such that the receptacle is retained in a single horizontal plane while rotating about the vertical axis.
