Sаm is gоing tо the gym; he wоuld like to improve his upper body muscle strength, аnd feels most comfortаble using weight machines to perform isolation exercises.  He starts by working his triceps brachii muscle. What movement will he be doing during the concentric phase of the exercise? [1] What movement will he be doing during the eccentric phase of the exercise? [2] Next, Sam wants to work his biceps brachii, brachialis, and brachioradialis muscles. What movement will he be doing during the concentric phase of the exercise? [3] What movement will he be doing during the eccentric phase of the exercise? [4] Sam finds a machine that allows him to perform both resisted (concentric) abduction of the arm at the shoulder and, separately, resisted (concentric) adduction of the arm at the shoulder. Which muscles will this machine target? Abduction: [5] Adduction: [6]
