When extending an arm into a straight position, the triceps is considered the agonist muscle and the biceps is the antagonist, since the triceps muscle generates the motion to straighten the arm and the biceps contracts to return the arm to the original position.
This exercise targets your shoulders, triceps, back and biceps. During arm circles you engage in a dynamic stretch, which means that you're stretching as you're moving. In addition to warming up your shoulder joints, arm circles increase circulation to you arms, fingers and shoulders. If you hold a set of lightweight dumbbells in your hands during arm circles, you can optimize the toning effect of the exercise. You'll notice the muscle tone when your excess arm fat reduces.
