Start: Attach the stirrup handles to the high pulleys of the crossover machine. Stand between the stacks and hold the handles with a crossover grip. Stretch out your arms in front of your face and slightly bend your elbows.
Finish: Pinch your shoulder blades back together, then pull the handles back until your palms face forward at shoulder level and your arms are even with your torso. Pause, then slowly return to the starting position.
Do this one side at a time by standing sideways at the weight stack pulling the handle across your body.
