This was something I've never considered before, but found it very interesting. Researchers found that by having your child do yoga, it can help with their ADHD:
Researchers in India assigned 69 schoolchildren with ADHD to a once or twice weekly yoga program. The "Climb-Up" yoga program was conducted in classrooms for one year. The therapeutic yoga based curriculum included yoga, meditation, and play therapy.
The participants behaviors were assessed with Vanderbilt questionnaires completed by parents and teachers.
The researchers found that 46 percent of students had significant improvement in teacher ratings of behavior and 92 percent of students in parent ratings.
How do you think your child would respond to it?
