Description

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

From this position, the heels are raised so the body lifts onto the ball of the foot (chusoku) with slightly bent knees.

The heels are then lowered back toward the floor while the legs extend, creating a stretch in the calf muscles and Achilles tendon.

The movement alternates rhythmically between: - rising onto chusoku
- lowering toward kakato


Purpose

  • strengthen the calf muscles
  • increase elasticity of the Achilles tendon
  • improve ankle stability
  • prepare for push-off and movement

Key technical points

  • controlled upward and downward motion
  • centered balance
  • full contact at the bottom
  • consistent rhythm

Comment

This exercise introduces elastic loading of the lower leg and prepares the body for explosive movements.
