How to Do the Exercise

Setup

Lie on your back with the working knee slightly bent and the heel resting on the surface.

How to perform it

Press the heel into the surface and gently pull it toward your body as if bending the knee, without allowing the foot to slide. Hold the contraction, breathe normally, then relax.

Dosage

2 sets, 10 repetitions with 5-second hold, Rest 30 seconds

Use it well

What to Focus On

Key cues

  • Dig the heel gently into the surface
  • Keep the pelvis down and relaxed
  • Breathe normally during the hold

Why use it

Restores hamstring activation and knee-flexion control with minimal joint movement.

When to use it

Useful when low-load hamstring activation is appropriate but active knee-flexion exercise is not yet well tolerated.

Common mistakes

  • Lifting the hips into a bridge
  • Contracting so hard that the hamstring cramps
  • Holding your breath
Adjust the challenge

Know When to Progress or Scale Back

Use your movement quality and symptom response to decide whether the current version still fits.

Progress when

  • You can maintain a smooth contraction for the full hold
  • The pelvis stays relaxed and still
  • Symptoms settle appropriately after the exercise

Scale back if

  • The hamstring cramps repeatedly
  • Pain increases and remains elevated afterward
  • The pelvis lifts or the foot slides during the hold

Was This the Right Challenge Today?

Use the same three signals that matter inside Therapeutic Edge recovery plans: how challenging the exercise felt, how well you controlled it, and how your body responded afterward.

Answer after the exercise and, when possible, after you know your later or next-day response. This checks one exercise today; it does not change or save a rehab plan.
