Development of the back muscles is tied in closely with development of the shoulder, posterior thigh and hip muscles . To better understand the role of each exercise, it is necessary to understand the various joint and muscle actions.
- Joint Actions and Muscles Most Involved
-
- Lower back:
- Extension hypertension – erector spinae
- Lateral flexion of the spine – erector spinae, quadratus lumborum, internal and external obliques and rectus abdominis
- Backward shoulder rotation – erector spinae
- The Pelvic Girdle (Hips):
- Anterior pelvic girdle rotation – erector spinae, psoas, iliacus, pectineus, rectus femoris
- Upward (lateral) pelvic girdle rotation – internal and external obliques, quadratus lumborum, erector spinae, latissimus dorsi
- Shoulder Joint and Shoulder Girdle:
- Shoulder joint extension – latissimus dorsi, teres major, lower pectoralis major, posterior deltoid, long head of the triceps
- Shoulder joint flexion – upper pectoralis major, anterior deltoid,serratus anterior, upper and lower portions of the trapezius
- Shoulder joint adduction – latissimus dorsi, terres major, lower pectoralis major, rhomboid, and pectoralis minor
- Shoulder joint abduction – deltoid, supraspinatus, serratus anterior, upper and lower trapezius
- Horizontal abduction – middle trapezius, rhomboid, upper latissimus dorsi posterior deltoid, teres minor, infraspinatus
- Horizontal adduction – serratus anterior, pectoralis minor, pectoralis major, anterior deltoid
