Abstract: A power rack adjustable telescopically in height, width and depth to work in conjunction with any barbell lift and any weightlifting equipment a first upright subassembly, a second upright subassembly, a third upright subassembly and a fourth upright subassembly. A first lateral subassembly is releasably connected to the first and second upright subassemblies. A second lateral subassembly is releasably connected to the first and fourth upright subassemblies. A third lateral subassembly is releasably connected to the second and third upright subassemblies. A weight safety catch is releasably mounted on each of the first and second upright subassemblies. The first and second upright subassemblies define an adjustable height of the power rack, the first lateral subassembly defines an adjustable width of the power rack, and the second and third lateral subassemblies define an adjustable depth of the power rack.
