With the hips squared forward in attacks and half-turned (hanmi) during defense, Zenkutsu-Dachi shifts the center of gravity forward, distributing approximately 70% of the body weight onto the front leg.

The front knee is bent with outward tension so that the knee sits vertically above the big toe. The rear leg is straight with the rear heel rooted firmly to the floor and the rear foot pointing as far forward as possible.

Stance Dimensions & Footwork

  • Width: The stance width varies between hip-width and shoulder-width depending on the flexibility and skill of the practitioner.
  • Length: The length is approximately twice the shoulder-width, creating a low, stable platform capable of absorbing direct head-on impact.
  • Rooting: The soles of both feet adhere firmly to the floor, anchored by outward torsional tension from the knees.
  • Stepping: Transitions between stances use the grounded supporting foot as an immovable pivot while the moving foot glides smoothly. Keep the hips on an even plane — avoid rising or bobbing during movement. The torso remains erect, upright, and without tilting.

Blocks in Zenkutsu-Dachi

Age Uke • Rising Upper Block

The arm moves upward and diagonally across the centerline, accompanied by axial rotation of the forearm. The movement originates from the hips, traveling along an exact trajectory to intercept overhead or facial strikes.

  • The wrist must finish higher than the elbow, with the back of the fist angled toward the face.
  • The lats (latissimus dorsi) absorb the shock of impact, while the core connects the upper body to the grounded foundation.
  • The half-facing hip position (hanmi) directs the line of force straight through the rooted rear heel into the floor.
  • The torso rotates smoothly without losing vertical alignment.

Gedan Barai • Downward Sweeping Block

The arm travels diagonally downward and across the body in a sweeping motion outward. It is primarily used to deflect powerful direct kicks to the groin or abdomen.

  • Focus intently on the final muscular expansion of the chest and the downward snap of the forearm.
  • The final position of the fist must align directly above the front knee, approximately one fist-width above it, preventing the incoming strike from slipping over or under the guard.
  • The chambering arm's retraction (hikite) must synchronize precisely with the hip rotation and the grounding of the lower body into hanmi.

Ude Uke • Middle Forearm Block

This block travels parallel to the chest, originating from the hip on the side opposite the blocking arm and driving outward until the arm forms a right angle (90°).

  • Deflects incoming direct punches aimed at the chest, solar plexus, or abdomen.
  • At completion, the blocking fist sits directly in front of and level with its shoulder.
  • The opposite fist chambers firmly at the hip.
  • In Zenkutsu-Dachi, the body settles into hanmi (profile), though this block is equally effective when delivered from other stances.

Uchi Komi / Uchi Te • Inward Sweeping Block

An exceptionally effective sweeping block against middle and upper-level strikes.

  • Both arms begin extended forward, with the blocking arm positioned above the retracting arm.
  • The blocking arm executes an unbroken, sweeping circular path that meets the opponent's forearm without clashing, redirecting the incoming momentum.
  • The movement terminates with the fist level with the ear, resting above the shoulder with the knuckles facing toward the ear.
  • The retracting arm pulls smoothly to the hip.
