For those who often have to raise their arms at work
For those who often raise up their arms at work, such as hair stylists, musicians, cooks, please lower your shoulder blades firmly by turning your shoulders behind.
When the shoulder blades are raised, the arm muscles are often used to lift the arms, causing fatigue and pain in the arms.
When the shoulder blades are lowered, the muscles of the back support the movement of the arm. Simply remember to "store your shoulder blades into the back pockets of you jeans !"
