Target muscles

The hamstrings of the kicking leg are stretched dynamically. The hip flexors of the kicking leg drive the kick. The quadriceps and gluteus maximus of the standing leg drive the steps and stabilize. The trunk braces against the alternating loading. As a dynamic stretch and warm-up movement, this opens the posterior chain while priming the legs for activity.

How to perform

Setup

Stand tall with feet together. Take a breath.

Execution

Walk forward, kicking each leg straight out in front to hip height with the knee fully extended. Reach the opposite-side arm forward to touch the raised foot — this increases the stretch through the hamstring and adds shoulder mobility. Keep the torso upright; don't fold forward to chase the foot. Continue alternating legs forward across the room.

Common mistakes

Bending the kicking-leg knee to make the kick easier. Keep the knee extended.
Folding forward with the torso to reach the foot. Let the foot come up to the hand.
Rushing the steps. Slow controlled kicks for the dynamic stretch benefit.
Not alternating arms. The opposite arm reaches each time.
Doing it cold. Warm up with some easy walking first.

Progressions and regressions

Regress to lower kicks (waist height) until the hamstring flexibility allows higher. To progress, kick higher (chest height for very flexible lifters), or chain with knee hugs and lunges for a complete dynamic warm-up.
