    Default Latissimus Dorsi Muscle Function

    I noticed last night that my mare is building quite a bit of muscle as she nears her 5 y/o year.
    I like watching the progress of muscle building to make sure she is using herself correctly.

    I noticed this muscle out of no where last night, I looked it up and it is called Latissimus dorsi.

    I know nothing of this muscle.... can anyone tell me how this muscle is built? Is this a good muscle to strengthen?

    It attaches to the humerus (front leg) and moves dorsally in a triangular fashion towards the spine; where it inserts on a large band of fascia over the spine from roughly T3 to the lumbar vertebra.

    It is involved in flexing the shoulder and movement of the front limb off the ground.

    It is normal for this muscle to increase in size with more training/exercise. It's one of the main muscles that can cause issues with saddle fit as it gets bigger so that may be something for you to look into.
