The agonists are the muscles that help you to do this exercise. The antagonists are the muscles that bring you back to a regular position instead of being stuck.
Deltoid
in the arm: bicep contracts (agonist) triceps relax (antagonist) in the leg: hamstrings contract (agonist) quadriceps relaxes (antagonist) remember the agonist is the muscle "agonising" to do the work - like pulling the joint.
The two functional characteristics used to classify muscles into classes are agonist and antagonist. Agonist muscles are responsible for causing movement, while antagonist muscles work in opposition to the agonist to help control the movement.
Any time you are doing an exercise where you are pushing a secondary mover will be be the tricep. An antagonist when doing a pushing exercise will always be the bicep.
the agonist of the muscle is a motion that contracts the body to move in its opposition the antagonist is the muscle that causes movement of the posterior and anterior terms of the human body.
Rectus abdominis is the prime agonist and the superior and inferior oblique muscles are synergists. Erector spinae is an antagonist including a number of other muscles of the back.
The primary muscles used in the lateral raise exercise are the deltoid muscles, specifically the lateral deltoid.
The lateral raise exercise primarily works the deltoid muscles in the shoulders.
During a lateral raise exercise, the muscles primarily worked are the deltoid muscles in the shoulders.
During a dumbbell lateral raise exercise, the muscles primarily worked are the deltoid muscles, specifically the lateral deltoid.
During a shoulder lateral raise exercise, the muscles primarily worked are the deltoid muscles, specifically the lateral deltoid.
