Exercise demo
In one line

A flowing lunge-and-rotate sequence that mobilizes hip flexors, hamstrings, and the thoracic spine in one movement — a high-value dynamic warm-up drill.

Detail

A multi-joint dynamic mobility drill that strings several positions together:

  1. Step into a deep forward lunge (right foot forward), back leg long — stretching the rear-leg Hip Flexors.
  2. Place both hands inside the front foot and let the hips sink (hip and adductor mobility; The Hip Complex).
  3. Drop the rear knee or keep it long, and rotate the trunk, reaching the inside-arm (right) hand up toward the ceiling — opening the thoracic spine (see Thoracic Rotations (Open-Book / Quadruped)).
  4. Return the hand down, then straighten the front leg to feel a hamstring stretch.
  5. Step back and repeat on the other side.

Performed as flowing, controlled movement (not a held static stretch), it develops active mobility (see Mobility vs Flexibility) across the hips, hamstrings, and thoracic spine simultaneously — which is why it is a favorite single drill in dynamic warm-ups (see Dynamic Warm-Up (Mobility-as-Training)). It pairs well after an inchworm (Inchworm).

Coaching:

  • Keep the spine long; rotate from the thoracic spine, following the hand with the eyes.
  • Move through each position smoothly; ~3–5 reps per side.
  • Front knee tracks over the foot; don't let it collapse inward.

Key facts

  • Lunge → hands inside foot → trunk rotation/reach → straighten front leg → switch.
  • Mobilizes hip flexors, hips/adductors, hamstrings, and thoracic spine in one flow.
  • Dynamic (flowing) mobility, not a static hold; ~3–5 reps per side.
  • High-value single dynamic warm-up drill.

The Hip Complex
The musculature spanning the hip — including the iliopsoas, tensor fasciae latae, sartorius and the iliotibial band — that flexes, extends, adducts, abducts, and rotates the hip.
Hip Flexors
The 4 major hip flexors — iliopsoas, rectus femoris, tensor fascia lata, sartorius — plus secondary flexors.
Dynamic Warm-Up (Mobility-as-Training)Closely related
A pre-activity routine of active, moving drills that take joints through increasing range while raising temperature and priming the nervous system — building usable mobility, unlike a static hold-and-relax stretch.
InchwormClosely related
Fold forward, walk the hands out to a plank, then walk the feet back in — a dynamic warm-up drill that mobilizes the hamstrings and posterior chain while bracing the core.
Thoracic Rotations (Open-Book / Quadruped)Closely related
Drills that isolate rotation to the mid-back (thoracic spine) — the joint-by-joint "mobility" segment — while keeping the lumbar spine stable.
Mobility vs FlexibilityClosely related
Flexibility is how far a joint can be moved, often with outside help. Mobility is how much of that range you can reach and control with your own muscles. Build both by stretching and by strengthening through full range.
