Set both attachment points to slightly above your head.
Feet positioned in an athletic stance slightly outside shoulder-width. Your knees are slightly bent and toes pointed straight ahead.
The core is braced and engaged with your shoulders pinned back and chest up.
Grab the left handle with your right hand and the right handle with your left hand. Stand in between the two stacks of weight, slightly away off the center line.
With your elbows slightly bent, retract and use your posterior shoulder to abduct both arms across your body.
The finished position should feel as if you are squeezing a quarter between your shoulder blades.
*Tips*
Keep your chest up. Don't let your shoulders roll forward.
You do NOT want the feeling of your upper traps elevating or shrugging.
Keep your shoulders blades down and back throughout the whole exercise.
Do not arch your back excessively, keep your core tight to combat this.
