i think is the deltoid muscle but I'm not sure tbh
The fixator is one of many muscles used during situps. The fixator muscle stabilizes one part of your body when you move another part.
muscles of the pharynx could be used with a muscle that is associated with the chin costalis popliteus cleido genio nuchal.
Mainly back and bicep. Or specifically the sternal portion of the pectoralis major, latissimus dorsi, teres major, posterior deltoid, the rhomboids, the middle and lower portions of the trapezius, and the elbow flexors.
Medial surface of the tibia.
So you don't lean back when you are doing leg lifts or chin ups
Chin-ups, just as most exercises use a primary & secondary muscle group. The primary muscle group would be the back (or latissimus dorsi). This is what helps to give that "V" - shape in the torso area. (along with slimming down the torso area, of course) The secondary muscle group would be the biceps. Depending on your grip position, you can focus either more on your "lats", or arms.
When muscles get used to doing an exercise a lot, and remember the exercise.
Stomache, side, and sometimes your back will hurt!

No muscle cells push, it just depends which muscle is doing the pulling. In a common joint, one muscle is used to pull the body part one way, and a different one is used to pull it back.
The fixators prevents any unecessary movement, Look into biomechanics for more detail. Is all about the way that the muscles moves. ie BICEP CURL: Agonist - Prime mover muscle: Biceps Antagonist - Opposing muscle group: Triceps. Synergist - Helping muscle group(assists): Brachioradialis. Fixators - Prevents unecessary movement: Abs and Back and Shoulders and wrists.
