5. Short description

The practitioner stands upright with the hands at the sides of the belt in the same starting position as in the previous exercise.

On the instructor’s command, the left foot steps forward a short distance. The rear foot remains in place and carries most of the body weight.

The movement is performed only with the toes of the front foot.

Two positions alternate according to the count:

  1. The big toe is lifted upward while the other four toes remain pressed against the floor.
  2. The four smaller toes are lifted upward while the big toe remains pressed against the floor.

The movement is performed in a controlled manner without the heel leaving the floor. The upper body remains stable and upright throughout the exercise.

6. Purpose

The purpose of the exercise is to:

  • develop individual control of toe movements
  • strengthen the small stabilizing muscles of the foot
  • improve balance when body weight is distributed asymmetrically
  • prepare the foot for stances and movements where one foot carries more load than the other
  • improve ground contact and stability in stances

In the Kyokushin technical system, the structure of the foot and its contact with the ground play a central role in balance and power transmission.

This exercise therefore continues the mobilization of the foot and prepares the practitioner for the following stages of Jumbi Undō where the ankle, knee, and hip are activated.

Comments

1. Romaji

The instruction hidari ashi o dashite literally means “step forward with the left foot” and is commonly used in warm-up sequences.

2. Structure

This exercise continues the progression from the previous moment where both feet are activated to a moment where one foot is loaded individually.
