Key difference
This is the same seated vertical pull, but the handles follow a fixed arc set by the machine instead of a free cable path. The guided path removes the need to balance the bar and keeps the range of motion identical from set to set, at the cost of less freedom in hand position and bar path.
When to choose it
Choose this when the cable station is unavailable or when a stable, repeatable path is preferred for hard sets close to failure. On models with independent handles, it also allows one side to be trained at a time.
