Hip External Rotator Strengthening
Strengthens the hip external rotators with a resistance band. Focuses on restoring balance between the piriformis and its synergists, reducing focal overload on the piriformis itself.
How to perform
- Starting position. Lie on your side with your knees bent at 90° and a resistance band around your thighs, above the knees.
- Step 2. Keep your feet together and engage your core.
- Step 3. Externally rotate the upper hip (opening the knee) against the band's resistance.
- Return. Return with control.
When not to perform
- Acute gluteal pain during the movement
- Trochanteric bursitis in an acute phase
