The complete movement capability of a joint; train through the full ROM a joint safely allows.

Detail

Range of motion is the complete movement capability of a joint, especially the bones. To ensure proper development of strength, every exercise should be performed through the full range of motion that the joint safely allows — deep squats are not recommended. An important caveat repeated in the source: ROM is not measured by how far the weights move; the user's actual joint ROM should be determined before performing exercise movements.

Key facts

  • ROM = complete movement capability of a joint.
  • Train through the full ROM the joint safely allows (deep squats not recommended).
  • ROM is NOT measured by how far the weight moves.

Full Range of Motion Principle ("ROM Is Not How Far the Weight Moves")
Strength develops over the range a joint actually travels — train through the full safe ROM, and remember ROM is the joint's movement, not how far the weight moves.
Deep Squats Not Recommended (Full-ROM Exception)
Every exercise should go through the full ROM a joint safely allows — but the squat is the exception: deep squats are not recommended; the safety range is thighs/quads parallel to the floor.
