abdominal muscle anatomy, The activity of the muscle tissue is completely dependent on its position! Yes, your personal hip adductors move your own legs inward toward one another if they are abducted, BUT they will certainly extend the hip in case you are in the hip is completely flexed, or extend often the hip if it is fully flexed. If you are just starting out, don't get baffled, just focus on the most obvious muscle action, but keep in mind that every single muscles function is positional, and will change based on the place of the joints.
Each muscle mass has some kind of function in most plane, and it has an unconventional action, concentric action, in addition to isometric action. Oh, through every plane, I avoid mean all 3 aeroplanes because there is an INFINITE # of planes (another main yet common anatomy error. ) What plane is usually cutting a diagonal together with your arm? If this blows the mind, I recommend taking the RTS accreditation ASAP!
