The chest – also known as pectorals or simply pecs – and tricep muscles are two unique groups in the upper body. The pectorals are large muscles originating from the sternum (sternal head) and clavicle (clavicular head). Both heads insert into the humerus and produce shoulder and arm motions (1<\/a>). <\/p>\n\n\n\n Specifically, your chest muscles are responsible for activities like horizontal adduction (such as bringing your arms in from the sides) and shoulder flexion<\/a> (raising your arm forward and up).<\/p>\n\n\n\n In contrast, the tricep is a minor muscle that consists of three heads and produces elbow extension (2<\/a>). Two of its three heads originate from the top of the humerus and insert into the elbow. The third (long) head originates from the scapula and inserts into the elbow. Thus, it crosses the shoulder, as well as the elbow.<\/p>\n\n\n\n\n\n Though unique in their functions, both muscle groups work together on all pressing exercises, which is why training them together is so beneficial (3<\/a>). In other words, you can train the two muscle groups in the same workout without one impeding the growth of the other. <\/p>\n\n\n\n Plus, given their synergistic functions, teaching the two muscle groups to work together has real-life benefits. For instance, you develop superior pressing strength, benefiting from some everyday activities and improving your sports performance.<\/p>\n\n\n\n Try Hevy<\/a> to create your own chest and tricep workout. <\/p>\n\n\n
