Ever wondered what makes your back muscles so strong? It is where muscle strength and power reside in a complex structure. Among these mighty muscles, let’s shine the spotlight on the latissimus dorsi, affectionately known as the “lats.” Picture this: with the help of a dominant muscle, which is under your armpit and reaches down to the bottom of your lower back, the key player, which exudes force and determination.

Now, the question “what are the lats?” becomes relevant. They are not really just sitting there all stretched-out and flaunting their beauty! These are all about movement, lift up your shoulders and do the flourish (envisage gracefully lower your upper arm) and bring the elbows back to the middle of the back, but with elegance. Well then, whenever you think about your back, always remember the tremendous lats and their central role in keeping you firm and provided with strength.

Origin and Insertion Points

The lats are comprised of an originating point that runs along the spine and extends down to the lower thoracic and lumbar vertebrae. This originating point also attaches it to the iliac crest of the pelvis and the sacrum. The muscle fibers that emerge from here fan out and intersect to form a thick tendon that inserts into the upper arm bone, referred to as the humerus. Its sheer size and prominence make it impossible to ignore in any discussion about back anatomy.

Functions of the Lats Muscle

So, to cut it short, what are the lats responsible for? Well, they’re versatile performers, primarily responsible for two key movements: shoulder flexion and shoulder abduction.

Shoulder Extension: The lats have an important function in the extension of shoulder joint, which allows you move your upper arms down and back. This does occur when executing the exercise such as pull-ups or lat pulldowns.

Shoulder Adduction: Along with that, the lats perform shoulder adduction, which is movement of the upper arms into the middle of the body. This process plays a major role on such movement as rowing and pulling a load closer to the upper body.

So, from the next time on, when going to the gym or doing any of the workout take a moment to acknowledge the incredible work that your lats are doing behind the scenes. They may be out of sight, but the power they are contributing to your strength and well-being is all too evident.
