A base supports the support members. Each support member bears synchronously and selectively movable, horizontally projecting spotting arms which are disposed in substantially the same horizontal plane. These support members are adapted to receive the barbell. Each spotting arm is coupled with a rod and cylinder assembly and each assembly is fluid actuable for synchronous movement of said spotting arms. An actuator or switch is provided for actuating said assemblies.
