The last post of this three part series will cover your shoulder complex and upper body positioning. I will discuss the three common postural distortions observed in my clients, and recommend flexibility and strengthening exercises to combat these asymmetries, or muscle imbalances.
Arms Fall Forward
Overactive (tight) Muscles
- Latissimus Dorsi: O – T7-T12, Iliac Crest (pelvis), Thoracolumbar Fascia, Ribs 9-12; I – Scapula (lowest point), Intertubercular Groove of Humerus
- Pectoralis Major/Minor: O – Clavicle, Sternum, Ribs 1-7; I – Greater Tubercle (humerus), Coracoid Process (scapula)
- Teres Major: O – Scapula (inferior portion); I – Lesser Tubercle (humerus)
- Coracobrachialis: O – Coracoid Process (scapula); I – Humerus (medial portion)
Underactive (weak) Muscles
- Mid/Lower Trapezius: O – T1-T12; I – Spine and Acromion Process (scapulae)
- Rhomboids: O – C7-T5; I – Scapula (medial portion)
- Rotator Cuff Muscles – S.I.T.S. Muscles
Subscapularis: O – Scapula (anterior portion); I – Lesser Tubercle (humerus)
Suprapinatus: O – Scapula (upper, posterior portion); I – Greater Tubercle (humerus)
Infraspinatus: O – Scapula (lower, posterior portion); I – Greater Tubercle (humerus)
Teres Minor: O – Scapula (lower, lateral portion); I – Greater Tubercle (humerus)
- Posterior Deltoid: O – Scapular Spine; I – Deltoid Tuberosity (humerus)

Overactive (tight) Muscles

- Sternocleidomastoid: O – Sternum (top portion), Clavicle (medial 1/3 portion); I – Mastoid Process (lower, lateral portion of skull, near jawbone)
- Scalenes: O – C3-C7; I – Ribs 1 and 2
Underactive (weak) Muscles
- Deep Cervical Flexors
Longus Coli: O – T1-T3; I – C1
