Grab a rope attachment and set the pulley at upper chest height on the cable machine.
Grip the rope from underneath using a neutral grip with your hands facing eachother. Keep your chest up and retract your shoulder blades.
Pull the rope back towards your face while at the same time imagining that you’re trying to pull the rope apart.
Pause momentarily in the fully contracted position and focus on squeezing your rear delts and upper back before returning to the starting position.
