The range of motion is a term which is used to describe the range through which a joint or muscle can move. The range of motion of a joint is dependent on several factors such as the stiffness of tendons or ligaments, activity level, age, gender and structure of the particular joint.

During training it is important to move through an as large as possible part of the available and safe range of motion. This results in a more effective training for the active muscles and flexibility is maintained or even increased. A limited range of motion can be detrimental to performance in sports and is related to developing physical problems such as low back pain. In addition a limited range of motion also increases risk of injury.
