What are the synergists in a push-up?
ExRx.net notes that when you perform a push-up correctly, you’re using three synergist muscles. The clavicular head of the pectoralis major, the anterior deltoid and the triceps brachii are found in your chest, shoulders and rear of your upper arms, respectively.
What is the stabilizer muscle in a push-up?
During the push-up exercise, the short head of the biceps brachii muscle acts as a dynamic stabilizer. This means the muscle activates at both ends—the elbow and the shoulder—to help stabilize the joints.
What is the purpose of a ninety degree push-up?
90 degree push-up is a calisthenics and total body exercise that primarily targets the chest and to a lesser degree also targets the glutes, lower back, shoulders and triceps.
Does the antagonist muscle relax?
In an antagonistic muscle pair, as one muscle contracts, the other muscle relaxes or lengthens. The muscle that is contracting is called the agonist and the muscle that is relaxing or lengthening is called the antagonist.
What is the opposite of a push-up?
The exact opposite of this would be a “pull” exercise, where you are pulling your body away from the ground using the strength of your arms — primarily your biceps — and your back. Your core stabilizers, hamstrings and glutes are also at work. Do push-ups for your chest and inverted rows for your back.
Is a push-up flexion or extension?
So the agonist muscles for a push-up are the pectoralis major, biceps (shoulder flexion), triceps (elbow extension), and serratus anterior, pec minor (scapular protraction). They are working concentrically during the up phase, and then eccentrically during the down phase—they are the agonists for both phases!
