Target muscles
The hip flexors of the back leg are stretched. The adductors of both legs are loaded — the front leg's adductor through inner-thigh stretch, the back leg's adductor through hip flexion. The hip mobility of the front leg is challenged. As a mobility movement, the frog lunge targets the hip and groin region brutally.
How to perform
Setup
Begin in a low lunge position — one foot forward, hands inside the front foot on the floor. The back leg extends straight back.
Execution
Rock the hips back and forth in a small range, feeling the stretch through the hip flexors and groin. To switch sides, walk the hands and feet through the center, transitioning to a low lunge with the other foot forward. Continue rocking.
Common mistakes
- Forcing depth that the body isn't ready for.
- Hunching the upper back. Stay open through the chest.
- Going too fast through the rocks. Slow controlled rocking.
- Doing it cold. Warm up the hips first.
- Forgetting to switch sides.
Progressions and regressions
Regress to a static low-lunge hold without rocks. To progress, deepen the position over weeks, or add a goblet weight at the chest for added trunk demand.
Programming notes
Mobility work. 2-3 rocks per side, repeated 2-3 times in a warm-up. Daily light work pays off for desk-job hip tightness.
