Fan Stretch

The Fan Stretch is a seated mobility exercise that opens the hips by stretching the inner thighs and hamstrings in a straddle position. It improves lower body flexibility and range of motion, which is essential for squat depth and overall hip health.

How Iridium Helps

While this is a bodyweight stretch, the AI optimizes your recovery by analyzing data from your previous leg sessions to recommend the ideal duration and frequency. If your training log indicates heavy squatting or deadlifting volume, the app adjusts this exercise to focus on gentle restoration rather than aggressive flexibility, preventing strain on recovering tissues.

Form Cues

Do
  • Sit on the floor with legs extended wide in a V-shape
  • Keep your toes pointing upward throughout the movement
  • Hinge forward from your hips, not your lower back
  • Maintain a tall, neutral spine as you lean forward
  • Breathe deeply into the stretch to release tension
Don't
  • Don't round your back aggressively to reach further
  • Don't let your feet or knees roll inward
  • Don't bounce or use ballistic movements
  • Don't hold your breath while stretching
  • Don't force the stretch beyond a mild discomfort

Common Mistakes

  • Rounding the spine excessively
  • Allowing legs to rotate internally
  • Bouncing to increase range
  • Lifting glutes off the floor
  • Tensing the neck and shoulders

Muscles Worked

This exercise primarily targets the adductors (inner thigh muscles), which are often tight in sedentary individuals and runners. It also provides a significant stretch to the hamstrings and glutes while requiring the erector spinae to work isometrically to maintain a neutral spine position.
