Many people take pain-free shoulders for granted, especially lifters. While it isn’t every day that you see someone get injured, you do see plenty of people with pains, pinches, weakness, or an inability to do any pressing movements.
Rotator cuff injuries are somewhat common due to many reasons such as poor posture, bad shoulder mechanics, and even from overdeveloped front delts. Mix in a touch of poor warming up and you have the recipe for a shoulder injury.
The rotator cuff is a collection of muscles that all have a specific function. Let’s see what the rotator cuff is made of so we can see how to help keep us injury free.
What Is The Rotator Cuff?
The rotator cuff is comprised of four different muscles in the shoulder:
- Teres Minor
With four different muscles controlling your shoulder, you see how easy it could be to pick up a shoulder strain or injury.
The teres minor’s main function is to stabilize the shoulder joint, helps draw your humerus into your scapula correctly, and works closely with the infraspinatus.
The supraspinatus acts as an abductor of the shoulder girdle and helps your arm move up and down on a horizontal plane. The infraspinatus attaches on the back side of the scapula and is one of the larger muscles in the rotator cuff.
Lastly, the subscapularis is the largest and strongest muscle in your rotator cuff. Its job is to medially rotate the shoulder joint itself.
Rotator cuff injuries are common among weight lifters due to the finicky nature of the muscles, the joint itself, and the effect your posture has on your shoulders.
