As a senior myself, my own favorite kind of machine is the appropriately named “Air Walker.” Seemingly, only Tri-Active America offered one in years past. (It’s a popular favorite in Tri-Active’s “exercise zone” facility that's located within Debs Park's multi-use sports zones in the city of Bell, for example.) But Greenfield now makes one as well; Norman Houston Park in Los Angeles City Councilman Bernard Parks District happens to have such a Greenfield Air Walker in it.
Well, anyway, I certainly do hope that this specific machine (whether made or sold by Tri-Active America or Greenfield) is indeed among any excellent exercise machines selected for installation in the new Maryland Avenue Park.
