Scaption and shrug increases strength and stability throughout the shoulders with an emphasis on the traps.
Standing tall with your feet shoulder-width apart, hold a pair of dumbbells at your sides with your palms facing each other. Keeping a slight bend in your elbows, raise your arms 45 degrees out from your sides. Stop when your arms are parallel to the floor.
Keeping your arms in the same position, shrug your shoulders up towards your ears. Pause, and then slowly lower the weights back to the starting position.
Avoid letting your back round throughout the movement. Instead, keep your chest up and stand tall throughout the exercise.
Do not raise the weights too high. Stop when your upper arm is parallel to the ground.
