Leg Length Test

Body WeightBeginner

The Leg Length Test assesses leg length discrepancies. This test helps identify potential issues related to posture and alignment.

  1. Lie flat on your back on a firm surface.
  2. Ensure your legs are straight and together.
  3. Measure the distance from the anterior superior iliac spine to the medial malleolus on both legs.
  4. Compare the measurements to determine any discrepancies.

How to perform the Leg Length Test

  1. Set up. Set up in a stable, balanced starting position appropriate for the Leg Length Test using your body weight.
  2. Brace and execute. Brace your core, control the descent, and move through a full pain-free range of motion while emphasizing your primary working muscles.
  3. Reset. Reverse the movement under control and reset between repetitions, keeping your form crisp on every rep.

Coaching cues

  • Move with intent — every rep should feel deliberate, not rushed.
  • Drive force through your working muscles rather than momentum.
  • Keep your breathing steady: exhale on the hard part, inhale on the reset.

Common mistakes

  • Using too much weight and losing positional control.
  • Cutting the range of motion short and missing the target muscle.
  • Letting your spine round or hyperextend instead of staying neutral.
