Flexibility

Also searched as: passive flexibility

Flexibility is the ability of tissues and joints to move through a range, often with an emphasis on stretch tolerance or passive range.

WBC translation

WBC treats flexibility as one ingredient, not the whole goal. The practical question is whether the range is useful, controlled, and appropriately loaded.

Why it matters

  • 1Helps readers understand why stretching aids are not magic lengthening devices.
  • 2Separates passive range from active control and joint capacity.
  • 3Encourages gradual loading rather than forcing a position.

Do not overclaim

  • Do not promise permanent tissue lengthening from a single stretch or tool session.
  • Greater flexibility can be unhelpful if it lacks control or irritates symptoms.

Evidence note

Stretching and range-of-motion research is substantial but context-specific; claims should distinguish short-term tolerance changes from durable capacity.
