Mobility Versus Flexibility: What Is the Difference?
'Tight' isn't always the problem. Understanding the difference between flexibility and mobility helps you choose the right tool for the actual limitation — instead of stretching something that doesn't need stretching.
Flexibility is available range. Mobility is your ability to actively control movement through a useful range. Most everyday limitations are about mobility, not just flexibility.
Definitions
Flexibility: the available range of motion of muscles and related tissues.
Mobility: the ability to actively control movement through a useful range.
Why stretching alone isn't always enough
A person may have plenty of passive range and still lack:
- Strength in that range
- Coordination
- Confidence
- Joint control
- Exposure to the movement
- Task-specific skill
A practical approach
- Identify the movement or task that is limited.
- Determine whether the person needs range, strength, control or practice.
- Use a suitable mobility drill where helpful.
- Follow it with a strength exercise that uses the available range.
- Reassess the task.
Example: struggling with squat depth
- Supported ankle movement
- Controlled squat to a comfortable box
- Leg-strength exercise in the range you have
- Gradual reduction in box height
- Reassessment
'Your hips are locked,' 'your body is out of alignment,' 'this stretch releases toxins.' These phrases sound scientific but they don't describe what's actually happening.
- 1.Range without control is fragile.
- 2.Mobility work is more useful when paired with strength in the range you're building.
- 3.The right drill depends on what's actually limiting the task.
