I've noticed that A LOT of the work we do in crossfit deal more with the back muscles while there isn't much of an emphasis on the chest muscles. What is the rationale for that?

I'm not complaining, I'm just wanting to know why.

Thanks,

Kris

The muscles of the posterior chain are simply more important in nearly every athletic movement. The glutes and hamstring are fundamental to explosive movements and enguaging the back is usually part of most exercises targeting them. Think of sprinters, football players, olympic lifters, powerlifters, ect. In most power/strength oriented sports extremely developed posterior muscles can be observed among the best athletes.

Another problem is the average person and even athlete does not realize the posterior chains importance. The muscles of the front like the quads and chest tend to be more showy so people tend to overwork them.

Many people also wind up with flexibility issues after overworking all of those front muscles. Most people who train the chest hard have fairly inflexible shoulders, for example.

It's not that back muscles are over-emphasized with CF, they're just drastically underemphasized everywhere else.

The anterior muscles are not more showy to other people, they are just more visible to the trainee.

Guys work their biceps in hopes of making their arms bigger, but it's the triceps that are the biggest muscles of the upper arm. Big triceps=big arms; big biceps=big biceps. Studies have shown that women respond more positively to a man with a V-torso (big back, narrow waist) than to a big chest. Ask any woman which she notices first - muscular quads or a muscular butt. There's no contest there. And as Matt said, the posterior chain is more important in athletics. The biggest muscles in the body are in the posterior chain and it's for a reason. It's the hamstrings that put the speed in the sprinter, the butt that puts the power in the pull and the back that holds it all together.

Back muscles are predominantly muscles of extension and external rotation. They are what keeps us upright... the muscles that fight gravity. Virtually every weight bearing endeavor relies on these "postural" muscles. Since humans are bipedal, strong posterior muscles are a must. Having said that, did you see Nicole and Eva's abs on todays WOD post?

We are hairless monkeys, with brains that are slightly more evolved. Climbing trees does not resemble (to my knowledge) pressing a bar up on a bench press station.

Crossfit = mad monkey skills.
