Exercises
1. DB Prone abduction with external rotation T: bench; abduct shoulders with thumbs pointing up until upper arm is horizontal; elbows slightly flexed
2. DB Prone flexion Y: bench; flex shoulders with thumbs pointing up until upper arm is horizontal, elbows slightly flexed
3. DB Overhead Press: sit upright; DBs in front of the shoulders; push DBs straight up until the arms are straight
4. DB Row: 30º from horizontal; one knee on the bench; pulls DB toward the ipsilateral lower rib
5. Push-up plus: push-up position on hands and feet or knees; keep torso rigid; push the body as high as possible off the floor by protracting the scapulas
6. Press-up: sit upright, feet on floor; straight arms; palms on edge of bench fingers pointing forward; dip down moving just the shoulder girdle
7. Ring fallouts: on the knees with the hands in the gymnastic rings, which are suspended just above the ground level

UPPER TRAPEZIUS
– Unilateral Shoulder Shrug, DB Lateral Raise, Prone “Y”, DB Low to High, Prone “T”, DB Row
Surface EMG of exercises for the trapezius and serratus anterior – 2003 – Ekstrom
Results MVIC
Upper Trapezius: was activated maximally with exercises requiring a great amount of upward rotation of the scapula
120% – Unilateral Shoulder Shrug
79% – Shoulder Ab-duction in the plane of the scapula >120º: DB thumbs up raise in the plane of the scapula finishing above 120º
79% – Prone Arm Raise Overhead: in line with the lower fibers of the lower trapezius
72% – Shoulder Ab-duction in the plane of the scapula <80º: DB thumbs up raise in the plane of the scapula finishing below 80º
66% – Diagonal Low to High: DB shoulder flexion + horizontal flexion + external rotation
66% – Prone Shoulder Horizontal Extension with External Rotation
63% – Prone Unilateral Row: face-down on a bench
