The Solar Savings Angle to Training in the Park: With as little natural Vitamin D as people get, as many taxes paid, it seems only right to be able to use one’s park for personal self-training so long as you take responsibility for yourself, the risks, and making sure you are using common sense, going slow, and testing yourself at your level of growth. Besides, economics sometimes make gyms and clubs too expensive, too logistically tedious, and yet again, more indoors activity.
Other Safety Tips: Make sure park rules don’t prohibit what you’re doing, and that the fixtures are stout enough to handle you. Some parks have weight limits. Some equipment is rusty. Don’t do this stuff over concrete, or thinly covered concrete or hard dirt. Find a park with soft ground under your swings. If you’re an adult, give kids first dibs on the park. If they’re using it, use a nearby field for calisthenics, sprints, i.e. whatever else you are cleared to handle by your doctors and physical configuration.
