South America is a great continent to travel on a budget, though you would be wrong to assume that every country in South America is cheap. The cheapest and most backpacker-favored countries are Peru, Ecuador and Bolivia, each attracting large numbers of budget travellers.
Latissimus Dorsi. The main muscle mover in the lat pulldown is the latissimus dorsi, or lats. They are located on the sides of your middle-to lower-back. You probably recognize the lats on bodybuilders because the muscle looks like wings that extend from underneath the shoulder to the lower back.rms. The three muscles that make up your biceps -- the biceps brachii, the brachialis and the brachioradialis -- are also used during the lat pulldown. When the bicep group contracts and shortens, your arm flexes. This flexion occurs when you pull down the lat bar and decrease the angle at your elbow.
Oh the Lats! Easily one of the internetâs favorite muscles. Canât reach overhead? Gotta be the lats. Canât do pull-ups? Better train those lats. On a trip to bat wing swole town? Gotta hit those lats! I must say, these muscles get a lot of attention. However, one area where I think they also play a role is in shoulder pain. Before I explain, a little anatomy about the lats, also known as latissimus dorsi: The lats attach from the humerus (upper arm bone), down to the thoracolumbar fascia, which inserts directly into the pelvis. You can see this in the picture of the lats in red. The lats function to extend and internally rotate the arm as well as to extend the lumbar spine (the latter being a lesser known thing I find)
