Human Growth Hormone

Back in Girl Scouts we would go on a hike at a park that would have a fitness trail. Along the fitness trail there would be stations set up where you do jumping jacks, pull-ups, walking a beam, etc. I have seen them by office buildings and apartment complexes too. What I want to do is find out what they are officially called so I can do a search online. Thanks! (PS: I am from the Schaumburg, IL area if that helps.)

Usually it is called a fitness trail.
