Strength and Physique

In this video I talk about developing the pec minor, which is a chest muscle located underneath the pec major.   The pec minor is a thin, flat muscle about equal in size to your biceps muscles.   When you build up the pec minor, it can contribute some serious thickness your chest. The great upper-chest development of swimmers is due to the activation of the pec minor, which is responsible for half of the freestyle stroke. Most chest exercises stress the pec major as  a prime mover and the pec minor as a stabilizer.   Very few exercises target the pec minor  specifically as prime mover.   The best exercise to target the pec minor is the LaLanne push-up with a narrow hand placement.   The LaLanne push up with a narrow hand placement targets the pec minor, which in turn will "push out" the pec major, making the chest look thicker.
