SERRATUS ANTERIOR, UPPER-MIDDLE-LOWER TRAP
– 3 Variations of the Push-up
Serratus anterior and traps during different phases of push-up+ on different surfaces and hand positions – 2016 – Gioftsos
– Thirteen healthy male right-handed subjects who led a sedentary life
Procedure

SERRATUS ANTERIOR, UPPER-MIDDLE-LOWER TRAP
– DB Overhead Press, Push-up Plus, Prone Flexion “Y”
Scapular Muscle Activity from Selected Strengthening Exercises Performed at Low and High Intensities – 2011 – Andersen
– 17 healthy women
Results – High Intensity
Serratus Anterior: Overhead Press 80 · Pushup Plus 70 · Prone Flexion “Y” 55
+ Upper Traps: Prone Flexion “Y” 75 · Prone Abduction “T” 70 · Overhead Press 60
+ Middle Traps: Prone Abduction “T“ 90 · One Arm Row 70 · Prone Flexion “Y” 70
+ Lower Traps: Prone Flexion “Y” 70 · Prone Abduction “T” 70 · One Arm Row 50
Exercises
1. Prone abduction with external rotation “T“: bench; abduct shoulders with thumbs pointing up until upper arm is horizontal; elbows slightly flexed
2. Prone flexion “Y”: bench; flex shoulders with thumbs pointing up until upper arm is horizontal, elbows slightly flexed
3. Shoulder (Overhead) Press: sit upright; DBs in front of the shoulders; push DBs straight up until the arms are straight
4. One-arm 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
