The classic barbell bench press is an internal rotator of the shoulders. Due to the constant seated/hunched position many people are in for the most of the day, the shoulders become excessively internally rotated. Unfortunately, the bench press promotes further internal rotation of the shoulders.

What does dumbbell external rotation work?
The external rotation exercise targets the infraspinatus muscle which is a very important muscle of the rotator cuff. The rotator cuff muscles help to provide some stability for the shoulder joint.
What are external rotation exercises?
Is external rotation of shoulder good?
Sufficient external rotation in shoulders helps keeping your shoulders healthy and improve your posture as well as the ability to reach and lift objects overhead.
What muscles do external rotation of shoulder?
The teres minor muscle externally rotates the shoulder; It is considered a fusiform muscle. The teres major provides internal rotation, extension, and adduction of the shoulder; it’s considered a fusiform muscle.
What is an example of external rotation?
Actions that use external hip rotation include getting into a car, pitching a baseball, and all other movements that require a person to rotate the pelvis while placing most of the body’s weight on one leg. The external rotator muscles can become weak due to injury, surgery, or prolonged periods of inactivity.
Are external rotation exercises important?
Why should you do it? This exercise strengthens the external rotators of the shoulder. Two of the four rotator cuff muscles are external rotators and they are important to stabilize the shoulder joint during movement.
Is external rotation the same as lateral rotation?
In lateral rotation, this movement is away from the midline of the body and occurs in the transverse plane. As with most twisting motions, strain, awkward positioning, and repetition increase the chance for a work injury. Another term for lateral rotation is external rotation.
How can I improve my shoulder external rotation?
What is internal rotation of the shoulder?
Your shoulder is capable of two kinds of subtle rotation, internal rotation and external rotation. Internal shoulder rotation involves rotating your upper arm toward the front side of your torso. External rotation involves rotating it away from the front side of your torso.
Is bench press bad for shoulder mobility?
Competitive weightlifters, he said, should avoid bench press “because it will restrict your shoulder mobility.
Does bench press restrict shoulder movement?
The bench itself can cause shoulder injuries by restricting the normal motion of the shoulder blades (scapulae). In turn, the shoulder joint (glenohumeral joint) will have to move excessively to compensate for the restricted movement of the scapulae.
What is normal shoulder external rotation?
Normal range of active movement of the shoulder has been specified by the American Academy of Orthopedic Surgeons (AAOS) to be 180° for flexion and abduction and 90° for external rotation [6].
How do you improve internal and external rotation of the shoulder?
Do you need to train internal rotation?
One of the most common questions I receive in reference to the shoulder is, “Do I need more internal rotation?” The answer is, “It depends.” More mobility isn’t always a good thing, especially when it comes to overhead athletes who often have excess motion at this joint.
What limits shoulder external rotation?
Ligaments. Superior Glenohumeral Ligament: Limits external rotation and inferior translation of the humeral head. Arises from the glenoid and inserts on the anatomical neck of the humerus.
What is the strongest rotator cuff muscle?
Subscapularis was the most powerful muscle and contributed 53% of the cuff moment; supraspinatus contributed 14%, infraspinatus 22% and teres minor 10%. The force-generating capacity of the subscapularis was equal to that of the other three muscles combined.
What muscle is the antagonist in shoulder external rotation?
Serratus anterior was defined as the antagonist muscle of the STJ for the external rotation.
What is external rotation of the arm?
External or lateral rotation of the arm represents the movement of the humerus when an arm flexed to 90° at the elbow is externally rotated around the longitudinal plane of the humerus such that the hand moves away from the midline of the body. It is the opposite of arm internal rotation.
What muscles are the external rotators of arm?
The prime muscle groups that externally rotate the glenohumeral joint are the posterior deltoid, infraspinatus, and teres minor.
What causes poor external rotation of shoulder?
Acromial impingement syndrome, also known as “shoulder impingement” – acromial impingement occurs when your acromion (edge of your scapula) impinges or presses on your rotator cuff during external rotation or when you lift your arm.
Where should I feel external rotations?
You want your shoulder to be tilted backwards and down, not pulled back, just activated down, and you’re supposed to feel the position to really feel it, and you should feel it in the back area here of the shoulder, not in the front and not down the arm.
What causes poor hip external rotation?
Prolonged sitting can contribute to weakness in the external rotators of the hip. Injuries and hip surgery are other common causes of weak hip external rotators.
What are the 6 deep external rotators?
The six deep external rotator muscles of the hip (piriformis (PI), quadratus femoris (QF), obturator internus (OI), obturator externus (OE), superior gemellus (SG), and inferior gemellus (IG)) play a role in both hip stabilization and rotation and are damaged and relocated during total hip arthroplasty surgery.
What does external rotation of the shoulder look like?
