Have you ever looked up Meetup.com on the web ? You put in your area and groups you might be interested in. That is how I started my hiking group that now has over 1000 members. In my area there are tons of groups that involve exercise where you join for free. You just meetup with people like yourself. It is a very interesting site. There are groups for just about everything and most of them are free or just a small voluntary fee, to pay for the small fee to keep the group running on the site.
Take a look, you might find some exercise buddies.
