Today I briefly worked my lats at the gym.
The lat is a big muscle that climbers love to use. They are best worked with either the lat pulldown or the pull up.
As I said, lats are big muscles that you use almost every time you go climbing, so they should be well trained, especially if you plan on climbing very steep terrain like the Riffelhorn.
They also play a role in stabilizing your entire spine. Little wonder they are the largest muscles in the upper body!
Have a fantastic day!
