description	Practice aikido as a defensive martial art emphasizing harmony, redirection, and controlled resolution. Covers centering and grounding, ukemi (safe falling and rolling), core techniques (irimi-nage, shiho-nage, kote-gaeshi, ikkyo), blending and tai sabaki (body movement), randori (multiple attacker practice), weapons awareness, and applying principles off the mat. Use when learning a defensive martial art that prioritizes de-escalation, developing the ability to redirect aggression without causing unnecessary harm, building safe falling skills, or cultivating calm centeredness under physical pressure.

Practice Aikido

Aikido practice → centering, blending incoming force, resolve conflict via controlled technique not strength vs strength.

Use When

• Learn defensive martial art → de-escalation + controlled resolution
• Redirect aggression → no unnecessary harm
• Build safe falling (ukemi) → any physical activity/emergency
• Cultivate calm centeredness under pressure
• Complement tai chi/meditation w/ partner practice (see tai-chi, meditate)
• Train awareness + response → multiple simultaneous threats

In

• Required: Practice space, padded/yielding (tatami, judo mats, grass; no concrete)
• Required: Comfortable clothing, full range (gi preferred; loose exercise OK)
• Optional: Training partner (essential for techniques; solo covers centering, ukemi, movement)
• Optional: Practice weapons (wooden: jo ~128cm, bokken ~102cm, tanto ~30cm)
• Optional: Exp level (beginner, intermediate, advanced; default: beginner)
• Optional: Time (min 20 min; rec 60-90 min)

Do

Step 1: Ground + Center

Every technique begins centered. No center → muscular struggle.

1. Hanmi (half-facing stance): one foot forward, shoulder-width, 60°
2. Knees bent slight → weight sinks → one-point (seika tanden), 5cm below navel
3. Shoulders relax fully → drop from ears
4. Extend awareness outward, anchor at one-point
5. Test: partner pushes chest gently
   • Resist upper body → not centered → relax, sink
   • Stable no effort → centered
6. Weight underside: heavy part of arm = underside; upper surface light, buoyant
7. Extend ki: project calm forward thru fingertips — intention, not tension

→ Stable, relaxed stance. Pushes absorb thru structure → ground, not muscles. Quiet mind, broad awareness.

If err: Rigid → holding tension. Shake arms/legs, 5 breaths, restart. Pushes displace → lower center (bend more), focus one-point. Centering deepens months — initial wobbliness normal.

Step 2: Ukemi (Falling + Rolling)

Receive technique safely. Most important skill — thousands of falls.
