Essentials of Strength Training and Conditioning, 4th Edition. Ch 9, pg 181-182 Which muscle is directly targeted during the pec-deck? a. deltoids b. pectoralis major c. triceps brachii - ANSWERANSWER: b. pectoralis major EXPLANATION: In the pec-deck movement, the idea is to create a long level out of your arms, therefore putting more pressure on the primary and secondary muscles. The pec-deck directly targets the pectoralis major, and does so in a way different than a bench press because the elbows are unlocked throughout the whole range of motion. This length in the arms makes the movement much harder. The deltoids and triceps brachii are assistance muscles, working with the pectoralis major to create the movement.
