Snatch Drill for Shoulder Activation

Using a PVC pipe and a long band for resistance start with your hands spaced out in a wide grip (snatch grip) position.
Part 1
Step 1: Pinch your shoulder blades together without arching your back
Step 2: Maintain that position (ISOMETRIC shoulder activation) as you hinge your body forward, do not let the bar slide down your leg or your shoulders round forward. This is the most challenging part of the drill.
Reasoning/Disclaimer: This drill is not meant to exactly simulate the bar path of the barbell during a snatch, but rather it is designed to specifically challenge the endurance and activation of your posterior cuff, lats, and core organization as you breathe and hinge.
Part 2
Step 1: Pinch your shoulder blades together without arching your back
Step 2: Bring the bar to your chest, elbows higher than your wrists. No other body part moves here. Performed for the specified # of reps.
