\nThe agonist in a movement is the muscle the produces the majority of force during a movement. If the movement is unweighted, the antagonist of the prime mover will provide resistance that gives the agonist something to work against and helps to control the movement. When a movement is resisted (like in weight training), there is no need for the antagonist to do this, as the weight itself is the antagonist. For example, if I was to bend my elbow to scratch my nose, my triceps would resist against the biceps as they bend the elbow. However, if I was to do a bicep curl using a dumbbell, the weight plays the role of the antagonist, and my triceps wouldn\u2019t need to work. \n<\/div>\n"},"keywords":[{"options":{"points":1,"occurrences":1,"caseSensitive":false,"forgiveMistakes":true,"feedbackIncludedWord":"none","feedbackMissedWord":"keyword","feedbackMissed":"you forgot to mention the agonist.
