Toy Soldier Walk

The toy soldier walk, sometimes called the Frankenstein walk, opens the hamstrings on the move by kicking a straight leg up to meet the opposite hand. The kicking leg gets a dynamic stretch while the hip flexors and core drive the leg upward. It is a lively way to finish a warm-up and rehearse the long-leg action of sprinting and kicking.

How to do it

  1. 1

    Stand tall with your arms extended straight out in front of you.

  2. 2

    Step forward and kick one straight leg up toward the opposite hand.

  3. 3

    Keep the kicking knee straight and reach the toes toward the fingers.

  4. 4

    Lower the leg under control and step onto it.

  5. 5

    Kick the other leg up to the opposite hand on the next step.

  6. 6

    Keep walking forward, alternating kicks with a tall posture.

Tips

  • Keep the kicking leg straight; height matters less than a locked knee.
  • Stay tall rather than folding the chest down to meet the foot.
  • Start with modest kicks and let the range grow as you warm up.

Variations

Common mistakes

  • The kicking knee bends to force the foot higher, trading the straight-leg hamstring stretch for a knee-driven high kick.
  • The standing leg's landing gets rushed and heavy instead of stepping down under control before the next kick starts.
  • The arms drop lower with each step instead of staying up at a consistent target height for the kicking foot to reach.
  • The reaching hand chases the foot downward to meet it halfway, instead of staying at a fixed height and letting the leg do the work of reaching up.

Frequently asked

How many reps of the toy soldier walk should a beginner do?
8 to 10 kicks per leg across a short walking distance works well as a warm-up finisher before running, sprint drills, or lower-body training. Let the kick height grow across those reps instead of adding more total reps early on.
How do you make the toy soldier walk easier or harder?
Make it easier by kicking to knee height or below and walking slower between kicks. Make it harder by kicking higher toward the hand each step, adding a brief pause at the top of each kick, or walking at a slightly faster pace while keeping the knee locked.
What is the toy soldier walk good for, and when is it not a good fit?
It dynamically stretches the hamstrings while rehearsing the long-leg action used in sprinting and kicking, making it a lively warm-up finisher for runners and field-sport athletes. It is not a good fit as a static hamstring stretch replacement for someone who needs to hold and calm down a genuinely tight, achy hamstring rather than move it.
