The Posterior Chain.

In CrossFit, one of our favorite concepts to throw around is that of training the “posterior chain”.  We talk about it with regards to most of the power and Oly lifts as well as the majority of lower body movements that we do.  What exactly, you may ask, is the posterior chain?  The posterior chain is the group of muscles that runs from your lower back down behind your legs, hence the name, posterior. These muscles include the erector spinae (low back), the glutes (butt), the hamstrings, and also the calves.  These muscles are ignored in most people’s gym training because they can’t be seen in a mirror without turning yourself around and who has time for that when the water fountain or pec deck might be free!  Now you know.
(By the way, the muscles that comprise the anterior chain are often referred to as the beach muscles. These include the chest, abs, and quads.  We don’t need to worry about those until it starts to get warmer out.)
