Anatomy

Latissimus Dorsi (Lats)

The large, flat muscles of the back responsible for pulling movements.

The latissimus dorsi are the largest muscles of the back, giving the V-taper appearance. They are responsible for shoulder adduction, extension, and internal rotation - essentially all pulling movements. Pull-ups, lat pulldowns, and rows effectively target the lats. Wide grip emphasizes lat stretch while close grip emphasizes contraction.

Examples

  • Pull-ups are the best lat exercise
  • Wide grip pulldowns stretch the lats
  • The lats create the V-taper look
