Karate: Front Stance
In karate, the front stance, known as zenkutsu-dachi (前屈立ち), is a fundamental position emphasizing stability and power. It’s widely used across various techniques, including strikes, blocks, and transitions in kata (forms).
Key Characteristics of Zenkutsu-Dachi:
- Foot Positioning: The front foot points straight ahead, aligning with the direction of the technique, while the rear foot turns outward at approximately 30 to 45 degrees. 
- Leg Placement and Weight Distribution: The stance typically spans about two shoulder-widths in length and one shoulder-width in width. The front knee bends so that it aligns over the ankle or slightly beyond, ensuring stability and readiness for movement. The back leg remains straight or slightly bent, with approximately 70% of the body weight distributed on the front leg and 30% on the rear leg. 
- Hip Alignment: Hips face forward (shomen) to facilitate effective execution of techniques.
Zenkutsu-dachi serves as a versatile stance, providing a solid base for delivering powerful offensive and defensive techniques. Its structure allows for effective hip rotation, crucial for generating force in strikes and maintaining balance during movements.
