Three Planes of Movement
The human body moves in three planes:
2) the Frontal plane — differentiates between our front and back sides, anteriors and posteriors, whatever you want to call it. Movements that travel vertically or horizontally, up and down or side to side, fall in this plane.
3) the Transverse plane — separates our upper and lower halves. A movement in the Transverse plane involves a kind of rotation or twisting, in which your upper and lower halves oppose each other.
Now think for a moment: in the world of CrossFit, which movements fall into which plane(s)? I’ll give you a hint. A better question to ask would be, “Which plane of motion is often left out?”
The answer? The Transverse plane. Even the Nine Foundational Movements all take place in the same plane, and it isn’t the Sagittal. In the real world, we don’t just move up and down, left and right, up and down, back and forth. We twist, we turn, we bend! If we truly want to develop functional fitness, shouldn’t we be moving in all three planes of motion?
