Description

The practitioner stands with the feet approximately shoulder-width apart and holds the sides of the belt.

From this position, the heels are lifted so the body rises onto the balls of the feet (chūsoku). The knees remain slightly bent throughout the movement.

The heels are then lowered in a controlled manner back toward the floor.

The movement is performed rhythmically between:

  • rising onto chūsoku
  • lowering toward kakato

Purpose

  • strengthen the lower legs
  • improve ankle control
  • develop movement rhythm
  • prepare for push-off and movement

Key Technical Points

  • controlled rising and lowering
  • keep balance centered
  • full contact in the bottom position
  • even rhythm
  • work through the full range of motion

Comment

This exercise prepares the lower legs for power and movement in training.
