Set up the same way you would for the Band Chest Press and then press the band until the arms are fully extended.
This is where it gets different.
Instead of reversing the motion of the press, you are going to open up your arms in that hugging motion like the Dumbbell Fly.
The difference is instead of doing it from a lying position, you're now standing.
This means you'll likely have to activate your core to greater extent to execute the move properly.
Once the arms are fully open, you're going to focus on using your chest to bring them back together.
Again, adjust your distance from the pole to create changes in resistance.
