My next project is to explore local outdoor gyms and exercise equipment. Growing up I remember that the New Hartford Town Park had a series of mostly wooden contraptions with instructions that formed an exercise course including things like stations for doing pull-ups, sit-ups, etc. I'm not sure I noticed anyone ever using them besides folks like me, a kid, wandering up to one, poking at it, shrugging and running off to pick dandelions. But now I am a little curious. It could be a fun excuse to see what's out there in my area. I have a few leads though I'm not expecting much.
The only fitness trail I have seen that seemed to actually get a little decent usage is the Burlington Greeway Fitness Trail. A cool idea for sure. While looking for places near me, I happened to come across this web page covering 35 Outdoor Gyms in Atlanta, Georgia which shows some really impressive options alas, in Georgia, but a good example of what could be.
Halfmoon Town Park
Address: 162 NY-236, Halfmoon, NY
The park map shows an official "Fitness Loop" along the trail:

I don't see much online but there is at least one photo of a step-up station:

I expect this will be the first park I check out since it is pretty close to my house and even closer to work.
East Side Recreation Park
Address: 226 Lake Avenue, Saratoga Springs, NY
Saratoga's East Side Recreation Park boasts a "walking/jogging path throughout the park with fitness equipment". Recent online discussions support the existence of an "adult fitness area" that was exactly one one person was looking for. I can't find any pictures of it, but satellite view shows some plausible images:

Wilton Town Gavin Park
Address: 10 Lewis Rd, Saratoga Springs, NY
Someone on Reddit mentions "Gavin Park also has a couple outdoor workout equipment pieces along the trail that circles the park!".
