It may be a rare sight to see an American child practicing yoga. “But yoga helps kids let out stress, relax and concentrate（专注）at school,” a California teacher said. Besides, children already have an advantage over adults in taking up yoga: flexibility（柔韧性）.
“Physically, children are already flexible, so it helps them to keep that flexibility that they already have; it helps them get stronger and have healthier bodies,” said Linda Masuhara, a teacher at the Yoga Seed Studio. The Yoga Seed is a charity group offering free yoga classes for kids.
To make her training fun, Masuhara has her students pretend（假装）they’re trees, frogs or butterflies. She said her yoga class doesn’t include religious（宗教的）training.
Yoga is a kind of meditation（冥想）that relaxes the mind and body, and a key point of yoga is breathing. Masuhara teaches her students to take deep breaths before reacting to something stressful（有压力的）. It is a problem-solving（解决问题的）tool for children, helping them think clearly in a stressful situation.
Gus Russell, 11, has been doing yoga for about three years. “It is something fun to do in the morning before school,” he said. “It makes me feel like I don’t have any requirements（要求）. No one is like, ‘You have to do this! You have to do that!’”
