Low-Pulley Crossover

I’m doing the Superhero Program by Christian Thibaudeau, and I’m about to start weeks 5-8. So I need to know how to do a low-pulley crossover. I tried googling it, but found no information on it. I don’t have the pulley setup to do crossovers, but I’d like to know what the movement is so I can maybe figure out a replacement exercise.

Do incline DB flyes instead.
