Abdominal.

More reps is not progression.

Ab training stalls because the only tool people have is doing even more reps, and after two hundred sit-ups you have trained endurance, not strength. Here you add weight instead: 100 kg in the stack, a chest pad that spreads the pressure over the upper body and a position that keeps the neck out of it, so you can go heavy without pulling on the head. The machine is 1440 × 1050 mm, 1688 mm high and weighs 275 kg. Stop counting. Start adding.
