Single-Leg Balance

A foundational proprioceptive exercise that challenges ankle stability, foot intrinsic activation, and neuromuscular control on one leg. The simplest and most specific prehab drill for runners.

  1. 01Stand barefoot on one leg with a soft bend in the standing knee.
  2. 02Lift the opposite foot off the ground, bending the knee to 90 degrees.
  3. 03Keep your hips level and your gaze fixed on a point ahead of you.
  4. 04Allow the ankle and foot to make small corrections to maintain balance — this is the training stimulus.
  5. 05Hold for the prescribed duration.
  6. 06To increase difficulty, close your eyes or stand on an unstable surface.
Why it matters

Running is a series of single-leg stances with a flight phase in between. If you cannot balance on one leg for 30 seconds with eyes open, you lack the baseline proprioceptive control needed for safe running. Poor single-leg balance is correlated with ankle sprains, calf strains, and even stress fractures — the foot and ankle complex needs this neuromuscular challenge to maintain its protective reflexes.
