Cable crossover

Place the pulleys above your head and stand in between them and hold them in each hand.

Step forward. Bend a little forward from the waist. Put your hands forward with a small bend on your elbows. This is the starting position. Now, keeping your arms and torso stationary, start extending your arms to the side in a wide arc and breath in. You should feel your chest stretching. Now, as you breathe out, get return to the starting position using the same arc movement. That is one repetition.
