Adductor Rocks

Adductor Rocks are a dynamic mobility exercise designed to mobilize tight inner thighs and improve hip joint flexibility. By extending one leg and rocking the hips back, this movement actively stretches the adductor muscles while reinforcing a neutral spine.

How Iridium Helps

While this is a bodyweight mobility drill, the AI tracks your perceived exertion and pain feedback to gauge your hip health and readiness for heavy lifting. If you report tightness or discomfort here, the system can adjust your upcoming lower-body compound lifts or suggest additional recovery protocols based on your training load. Additionally, tracking completion of mobility work helps the AI correlate flexibility improvements with your squat depth and deadlift performance over time.

Form Cues

Do
  • Start on all fours with one leg extended straight out to the side
  • Keep the sole of your extended foot flat against the floor
  • Maintain a flat back as you push your hips backward toward your heels
  • Exhale deeply as you sink into the stretch
  • Return to the starting position with a controlled forward motion
Don't
  • Don't allow your lower back to round or arch excessively
  • Don't let the foot of the extended leg lift off the ground
  • Don't bounce or use momentum to force the stretch
  • Don't hold your breath while rocking back

Common Mistakes

  • Rounding the lumbar spine
  • Lifting the foot edge
  • Rocking too fast
  • Hyperextending the neck
  • Overstretching into pain

Muscles Worked

This exercise primarily isolates the adductor magnus, longus, and brevis muscles of the inner thigh, promoting length and tissue quality. It also dynamically mobilizes the hip capsule and engages the core stabilizers to maintain pelvic neutrality during the rocking motion.

Primary

Hip Flexors

Secondary

Quadriceps
