Question for sahms

So my son is almost 9 months and I’m a stay at home mom. I have two elementary aged kids who are in school during the day. I’ve been wanting to join a group or team sport/activity that I can do maybe once or twice a week while my kids are at school but I haven’t been able to find anything that I could do except for in the evenings. I want to be finished before my kids get out of school so I can be home with them and my husband when he gets out of work. Basically my question is, how do you stay active? And do you have a group that you meet up with during the week? If so, how did you find them?
