CanFitPro Personal Training Specialist Practice Test

Flexibility refers to the ability of a joint to move through its full range of motion. This allows for greater movement in the joints and can lead to improved posture, balance, and physical performance. Option A is incorrect because it is referring to the body's composition, not its ability to move. Option B is incorrect because balance is a separate concept from flexibility. Option D is incorrect because cardiovascular exercise focuses on the heart and lungs, not joint movement.
