The importance of Oblique work

March 14, 2016

There are 3 types on contractions : eccentric (think breaking,deccelereation),isometric (stabilization),concentric (action created by shortening the muscle).All muscles are created equal but their function differs.Some are better suited for concentric contraction like the quads or the triceps,whereas some muscles are designed more for eccentric or isometric.This has nothing to do with their composition but more to do again with their function

For example let's take a look at the abdominals (rectus abdominis).Concentric contraction for those means flexion of the trunk,which is not something you need a lot of in lifting.You'll use flexion for bodyweight movement but under heavy load that is something you would try to avoid (hopefully),the abs are mostly there for breaking and stabilizing.We are built a certain way and there is no denying evolution (again hopefully) so even though you can train your abs by doing crunches (flexion of the trunk - concentric) it would be wiser to respect the function of the abs when you are trying to build a strong core

By the way,this can be said about many different muscle groups in the body.I actually classify them in 3 categories : movers - stabilizers - breakers.Muscles can do all 3 obviously but usually are better at one than the others
