Pulley Row.

The back runs out of weight before it runs out of reps.

Rowing is the exercise where you most quickly hit the ceiling of what the machine has to give, which is why there is 120 kg in the stack here, changed with a pin in 5 kg steps. The pulley does not lock you to one grip: a wide handle, a narrow grip or one handle at a time pull from the same load, so you can change the angle of attack between sets instead of changing machine. And since no pad sets the distance for you, you hold the upper body yourself and get the full range, from a full stretch forward until the shoulder blades meet. The frame is 1830 × 1090 mm, 1770 mm high and weighs 225 kg empty. The back is built from pulling, not from enthusiasm.
