What is the Rotator Cuff ? 🏋🏼♂️
I was talking to a client earlier this week about the shoulder joint and rotator cuff, which she happened to mention how often we use the word “rotator cuff’’ but don’t entirely understand what it or they actually are…
The rotator cuff is a group of 4 muscles that surround and anchor the head of the upper arm bone to the socket of the shoulder joint, making the joint stable and supported for movement.
To get a better understanding of why they’re important, I like to compare the shoulder joint to the hip joint…
Like the hip joint, the shoulder has a ball and socket joint whereby the top of one bone fits cupped within a hollow socket of another.
However, where the hip joint fit securely, tight and stable, the shoulder joint is more like a golf ball resting on a tee. —
Therefore, the shoulder relies on 4 muscles which we know as the Rotator Cuff, which anchor and stabilise the shoulder to allow movement. —
because they play such an important role in enabling movement, it is another reason why niggles and injuries are so common; especially amongst gym goers. —
So remember, always warm up, always use appropriate weights and always maintain good form. - 1 month ago
