Muscle tone refers to the degree of steady tension in the muscle; an unconscious low level contraction as a result of motor unit activity even while at rest or sleeping. Essentially, muscle tone is what makes your muscles still feel somewhat firm while you are at rest and when you aren’t intentionally tensing them. In its more common use, the term refers to leanness in the body, muscle definition and shape.
