How to find an irl workout partner

Posting for a friend. No really, I prefer at-home videos or runs in the nearby park.

How do I find a workout buddy as a late 40s man? I’m not a social media person, always lurking on Reddit and now Lemmy/kbin. No FB, IG, linked in… But I can push myself better when I’m not alone. I like to vary between bicycle, jogging, calisthenics, cardio, also with changes in venue. Our Midwest city has various parks thankfully.

What strategies do you suggest for connecting with other people?
