Horizontal shoulder abduction is a great way to strengthen your shoulder and upper back muscles. Targeting these muscles helps promote good posture, and strengthening these muscles helps avoid injuries while doing everyday activities such as lifting or reaching.
Stand tall with your feet hip width apart.
Hold a resistance band with both arms straight out in front of you with your elbows extended.
Your arms should be at about a 90 degree angle to your body and your palms should be facing up. Your arms should be shoulder-width apart.
Keeping your arms straight and at chest level, pull the band out to the sides with both arms as far as is comfortable while squeezing your shoulder blades together. If it’s possible for you, you can extend until your arms are out to your sides in line with your shoulders, but don’t go beyond that. Then slowly return to your starting position.
Think about squeezing a pencil between your shoulder blades.
