The lunge with spinal twist (sometimes called the “world’s greatest stretch”) combines hip flexor lengthening with thoracic rotation in a single movement. It is one of the most efficient warm-up exercises for full-body mobility.

Setup

  1. Step your right foot forward into a deep lunge, placing both hands on the floor inside the front foot.
  2. Keep the back leg straight and strong, with the knee off the ground.
  3. Lift your right hand off the floor and rotate your torso to the right, reaching your right arm toward the ceiling.
  4. Follow your hand with your eyes and hold the rotation for 2–3 seconds.
  5. Return your hand to the floor and repeat for 5–6 reps, then switch sides.

Coaching Cues

What to feel:

  • A stretch through the hip flexor of the back leg
  • A rotational opening through the mid-back (thoracic spine)
  • The front-side groin area gently stretching

Common mistakes:

  • Rotating from the lower back instead of the thoracic spine
  • Letting the front knee collapse inward — keep it tracking over the toes
  • Rushing the rotation — pause at the top to get the full benefit

Programming

Parameter Recommendation
Reps 5–6 per side
Sets 2–3
Frequency Before every training session
When to do it Pre-workout warm-up, lower body focus, full mobility session

Progressions

  1. Beginner: Drop the back knee to the ground for stability.
  2. Intermediate: Full version with back knee off the ground.
  3. Advanced: Add a hamstring stretch by straightening the front leg after the rotation, then re-bending to continue.
