Frog Stretch

The Frog Stretch is a floor-based mobility exercise that deeply targets the inner thighs, groin, and hips. By widening the knees and sinking the hips back, it helps improve hip abduction range of motion, which is essential for squat depth and lower body flexibility.

How Iridium Helps

This app optimizes your mobility work by tracking the duration and intensity (RPE) of the hold relative to your recovery status. By integrating HealthKit data, the AI can detect factors like high fatigue (low HRV) or specific phases of your ovulation cycle that affect ligament laxity, adjusting the prescribed hold time to ensure you stretch effectively without risking injury or over-mobilizing.

Form Cues

Do
  • Start on all fours with knees wider than hip-width
  • Turn feet out so inner ankles touch the floor
  • Push hips back toward heels gently
  • Keep your spine neutral throughout the hold
  • Breathe deeply into your belly to relax the hips
Don't
  • Don't arch your lower back aggressively
  • Don't force your knees wider than comfortable
  • Don't hold your breath while stretching
  • Don't let your hips shift too far forward

Common Mistakes

  • Excessive lumbar arching
  • Rounding the spine forward
  • Tensing the inner thighs
  • Shifting weight onto hands
  • Forcing the stretch causing pain

Muscles Worked

This exercise primarily targets the adductor group (inner thighs) and the groin, muscles that are often tight in sedentary individuals. It also provides a secondary stretch to the hip capsule and glutes, helping to open the hips for deeper squatting mechanics.
