5. Short Description¶

The practitioner stands in the starting position for Jumbi Undō with the body upright and the hands holding the sides of the belt. The feet are placed slightly apart and the body weight is distributed evenly over both feet.

The movement is performed simultaneously with both feet and alternates between two positions:

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

The movement is performed rhythmically following the instructor’s counting. The body remains stable without leaning forward or backward.

6. Purpose¶

The purpose of the exercise is to:

activate the small muscles of the foot
improve neuromuscular control of the toes
increase mobility in the distal joints of the foot
strengthen the stability of the foot’s support structure
prepare the feet and lower legs for load-bearing in stances and movement

In Kyokushin training methodology, stable contact between the foot and the ground is emphasized because the foot forms the foundation for balance, stances, and power transfer in techniques.

This exercise therefore functions as the first activation of the body’s support structure, before the warm-up continues with mobilization of the ankle, knee, and hip in the following stages of Jumbi Undō.

Comments¶

1. Romaji

The instruction ashi no yubi o ugokashite kudasai literally means “move the toes.”
In dojo practice the instruction is often shortened, but the full form is kept here for clarity.

2. Terminology

The term ashi no yubi refers specifically to the toes (literally “foot fingers”), which is standard terminology in Japanese anatomical description.

3. Structure in Jumbi Undō

Many Kyokushin warm-up sequences begin with activation of the toes before progressing to ankle and knee mobility, reflecting a movement sequence that develops from the ground upward.
