Triathlon encompasses swimming, biking, and running, and so it involves almost all of your muscles. Your "tri muscles" are those muscles that carry the bulk of the muscle load for swimming, biking, and running. For swimming, it's your lats, chest, and shoulders. For biking and running, it's your quads, hamstrings, glutes, and calves. Another key muscle group area is commonly referred to as your "core muscles," which include the abdominal muscles, the lumbar region (or lower back), and the thoracic and cervical region of the spine. These muscles serve to provide stability, support, and a solid base for the rest of the body to function maximally.
