Input (English): [header] How to teach yoga to kids [title] Set time limits for children according to their age. [step] Kids' bodies are still developing, so poses should not be held for too long, and the overall yoga session should match their age and ability. [substeps] Allow children 5 years old and younger to spend up to 1 minute or 60 seconds on each exercise or pose. <sep> (A) Younger children should only focus on asana, or relaxation routines, where your concentration is broken. Other exercises will include bending your legs backwards and placing your hands on your hips. (B) The total yoga session for small children should not be more than 15 minutes. Allow children who are 6 and older to hold poses and do exercises for up to 1-1/2 minutes, or 90 seconds. (C) Instruct them not to lift any weights or, if asked to, only do so one at a time. Children should not lift anything heavier than a pencil weight. (D) Demonstrate the methods in the videos and accompanying publications, and enforce these rules. If more children may be performing yoga poses during the day, supervise them closely with their parents and encourage them to sign up in another class if appropriate.
