Mobility

In training, mobility usually means the ability to reach and actively control a useful range of motion at a joint or during a movement. It combines available range with the strength, coordination, and control needed to use that range. Mobility is therefore commonly distinguished from flexibility, which is more often associated with passive range or the extensibility of muscles and other soft tissues.

This distinction is practical rather than universal. A 2026 review of the terminology notes that professional organizations and researchers define mobility, flexibility, and range of motion in different ways. When comparing advice or studies, check what was actually measured instead of relying on the label alone.

Mobility is specific to a joint, direction, and task. Someone may have enough hip flexion for a deep squat but limited shoulder motion for an overhead press. A restriction can reflect bone and joint structure, soft-tissue tolerance, current temperature, pain, or insufficient strength and skill near the end of the range. It is not always a "tight muscle" that needs more stretching.

To improve mobility, practice the movement you want to perform and address the factor that limits it. Options include controlled dynamic drills, pauses or light resistance near the end position, and full-range strength exercises. A systematic review and meta-analysis found that resistance training with external loads increased joint range of motion and, on average, did not differ significantly from stretch training in the available comparisons.

More mobility is not automatically better. The useful target is enough range for your activities, together with stability and control. In strength training, judge a mobility drill by whether it improves the required position and form without creating pain, instability, or fatigue that interferes with the session.
