Final answer:
Muscles often come in pairs for balanced movement, such as the hamstrings and quadriceps which move the legs during running. The cour four stretch likely involves stretches for these muscle groups plus others involved in lower body function.
Step-by-step explanation:
Yes, muscles commonly come in pairs within the human body, which allows for balanced movement and control. For example, the hamstrings located at the back of the thigh are paired with the quadriceps muscles on the front of the thigh. Together, these muscle pairs are essential in activities like running, as they work in concert to allow the legs to move back and forth efficiently.
The cour four stretch sequence typically includes stretches that target these key muscle groups. Although not specified in the question, a typical 'core four' sequence might involve stretches for the quadriceps, hamstrings, hip flexors, and gluteal muscles, as these are all essential for lower body function and stability.
