Question

a warm - up routine prepares the body for vigorous exercise, especially the

a. joints
b. legs and feet
c. muscles
d. bones

Explanation:

Warm - up routines increase blood flow to muscles, which helps to loosen them and prepare them for more intense physical activity. Muscles need to be warmed up to function optimally and reduce the risk of injury during vigorous exercise. Joints (A) are also important, but the primary focus of a warm - up in terms of preparing the body for exercise (especially in a general sense) is on muscles. Legs and feet (B) are body parts that contain muscles, but the question is more about the general body part category. Bones (D) are less directly the focus of a warm - up routine compared to muscles.

Answer:

C. muscles
