Step by Step Guide
Begin standing with the feet hip distance apart and arms straight up in a “T” at shoulder height with the palms down.
Swing the arms in front of you and cross each other so that one is on top of the other. Go as far as you can to feel a stretch in the shoulders and upper back.
Return the arms back to the “T” start position.
Repeat for the desired reps.
A common mistake is performing arm crossovers while in a shrugged position. The focus of this is to stretch and warm up those upper back - not contract it. So instead, keep a nice and tall posture with the shoulders down while performing these arm swing crossovers.
