Glute Trainer.

The glutes, without the lower back paying for it.

A hip thrust with a bar usually means a bench, a mat, a bar you have to roll over your hips and a lower back that complains long before the glutes do. Here the upper body rests against the pad while the hips extend against the load, so it becomes pure hip extension from the first rep to the last and nothing else is allowed to help. The plates go on pegs in the frame, so you add weight when you want without rebuilding anything. The machine is only 807 mm high, but measure 1791 × 1562 mm on the floor before it arrives. Dead weight 189 kg. No bar to roll. No mat to fetch.
