Steps
Step 1: Stand upright facing the TRX anchor, keeping your feet slightly staggered.
Step 2: Insert your arms into the TRX handles, and maintain them at wrist level.
Step 3: Proceed to engage your back and shoulder muscles by pulling back on the TRX straps; the straps are fully extended and taught.
Step 4: While keeping the tension, process to lift your arm above your head, and back down, as if creating a Snow Angel in the snow, focusing on keeping your shoulders and upper back muscles engaged.
Step 5: Repeat this movement several times.
How to progress the exercise
Using a weighted vest will add more resistance to this exercise. Executing this movement either on one leg, or pulling with only one arm, or doing the whole movement with one leg and one arm is much more of a challenge that will require greater core control and concentration. Of course, you can always add a BOSU or stability disc for greater workout intensity.
Additional Information
A solid plank position is important for maintaining good posture during this exercise. If uncertain, revise the TRX Plank.
