Try a few different CrossFit gyms near you; at least one is likely to have a strong social element. CrossFit is the closest thing there is to secular church, and most of the reason people go to church is for the social aspect.

CrossFit has its downsides (much ink has been spilled elsewhere), but the social element makes up for a lot.

You can easily end up doing 5-7 sessions a week there, with a consistent cohort of people that you develop relationships with.

Edit to add: CrossFit classes also add an element of structure to a daily routine that is not work related. This is really important. You don't have to plan anything for the class, other than show and and do the workout. But showing up at social event consistently has an impact all through your day.
