What muscles make up your posterior chain and why are they such a big deal? Other than having plump glutes, what’s the point of building the backside of your body?

S&C Priority #1: Build That Back

I’ve worked with athletes of all levels — everyone from strength and power athletes to the general population of weekend warriors. One common trend I’ve seen through so many people is the lack of awareness of just how important the body’s backside is for everything fitness.

It’s easy for people to get fixated on the beach muscles of the front of the body (aka “show muscles”), like your chest, biceps, abs and quads, but true performance typically comes from the musculature of the posterior chain (aka “go muscles”).

Your hamstrings, glutes, lats, and the muscles of your upper back usually determine the output and capability of the movement patterns from the beach muscles on the front of your body.

Let’s look at a breakdown of the musculature that determines show from go muscles.

Long vs. Short Muscle Fibers

Longer muscles typically have an architecture of parallel fiber arrangements, which bias them for fast-twitch contractions and power generation. Many shorter muscles have pennated (wing-like) fibers, which have a greater concentration of slow-twitch/high-force capacity.

When we look at the posterior chain, we see a lot of long muscles with parallel fiber arrangements, which means tons of power potential from the movement patterns associated with them. Think squats, deadlifts, cleans, and sprinting.

In many cases, the movements dominated by anterior (front-body) chain muscles are limited in output based on the development of the posterior (back-body) chain muscles.

Why Are Your Posterior Chain Muscles So Important?

Everything involving the backside of your body should be priority #1 from an exercise selection standpoint if you care at all about your overall strength & performance.

Programming Methodology

No matter what kind of training split you run, prioritizing the pulling muscles early on in a session or prior to big push/pressing days is the way to go. Executing your meaty pulls first and focusing on good form can set your body up for optimal output in exercises like your bench press or squat.

If you’ve achieved a significant strength level with anterior-chain dominant exercises like squats and bench press, then you know how the setup works. Before you execute the “push” or concentric portion of the lift, you start with a controlled full-body “pull” or eccentric lowering of the weight first.

The stronger you are at pulling anything with neuromuscular efficiency, the higher your chances of gaining strength/power in the concentric portions of other lifts involving similar joints.

Here’s a quick list of posterior chain dominant exercises and guides on how to execute them with solid form.
