I mentioned before that we were going to talk about exercise. It's so important that it deserves its own section.

To start out, I put "work out" in quotes because I don't want you to think you need to have your child in the gym seven days a week working out really hard. Starting small, as we talked about in the first section, is an excellent way to start.
There are tons of different ways to work exercise into your child's life, along with encouraging a more active lifestyle in general. Remember, it's best if you do it with them.
It turns out exercise is a major win for children with autism. A meta-analysis that looked at 16 different studies found that there were "robust benefits of physical exercise on the patients' motor and social functioning [51]." To be more specific, they saw a 35% improvement in the ASD symptoms as a result of exercise.
What was interesting, and something to take into consideration is the individual programs (think your child and you or their therapist) had a bigger impact than group programs. This was surprising since their social skills improved more in the individual exercise programs, which seems counter-intuitive, but it's what they found.
The problem with group vs. individual is that they couldn't find any study that looked at exercise that was "naturally grouped based," such as soccer or basketball. It appears that all the studies that did group exercises were more like an exercise class you'd see at your local YMCA.
Exercise looks like it can be a big win for your child, especially since it doubles down on a lot of the things we mentioned before.
