Which is a fancy way of saying the ridge on the upper outer part of the upper arm. Those of you who haven’t studied anatomy are probably sighing with relief after trying to learn all the origins! Nestled between the pec major and teres major, the lat inserts on the intertubercular groove of the humerus. Insertion: Despite numerous points of origin, the lats only have one point of insertion.Finally, there is the scapular origin - located on the bottom tip of the scapular - called the inferior angle. The vertebral portion is attached to the spinous processes on vertebrae T7-T12, running from the bottom of the neck to the top of the ribs. The former - as the name suggests - comes from the bottom 3 ribs. Going up the back, we have the costal and vertebral origins. Firstly, the iliac attachment located on the top of the iliac crest, at the top of the back of the pelvis. Origins: The lats have 4 different points of origin.The lats - alongside the trapezius - are the most superficial muscle in the back, covering everything from the iliac crest up (excluding where the traps are).īeing the widest muscle in the body, the lats are spread thin and have multiple attachment points and functions. Narrower grips underhand pulldowns require greater bicep contribution, while wide overhand pulldowns stress the teres major more. While the biceps contribute to the movement by flexing the elbows.įorearm position and grip width influence the degree of involvement of these muscle groups. The teres majo r has a supporting role in the pulldown, assisting in adduction (pulling the arm in towards the body). The lower traps depress the shoulder blade as you pull down, while the mid traps and rhomboids retract the shoulder blades, pulling them together. However, this compound movement requires a lot of support from surrounding muscles to execute it efficiently. Unsurprisingly the primary target and mover of lat pulldowns are the latissimus dorsi. Lat Pulldown Muscles Worked (the Clue is in the Name) This article will outline the anatomy and function of the lats, before providing 9 alternatives that are more accessible or hit the lats in a way pulldowns just can’t. Further, a lot of people understand the benefits of altering exercise selection for the development of their muscles. However, with the rise of at-home training and limited access to gyms people have had to get more creative, thinking outside of the box when it comes to packing on mass. Anyone with the aim of developing a wide, V-tapered back would turn to make lat pulldowns their first port of call. Lat pulldowns have been the primary weapon of choice to build a bigger back for gym rats and bodybuilders for decades.
