They should be unsteady but relatively safe, making it a great way to walk across, non-linear “ground” and activate all the muscles and connective tissue in your lower body (and balancing neurons in your brain). The key is to get stones that are flat enough that you can stand on them but also have some wobble to them. Then, make a walking path using the stones that players have to traverse. Or just head down to the landscaping supply store and fill your truck/trunk with some decent sized stones. River stones for a balancing pathwayĮvery time you spend a day at the creek or river, grab a few large flat-ish stones and take ’em home. You can use them for crawling-bear crawls along a 2×4 is a great exercise and a nice change of pace for an obstacle course. 1×2 if you really want to learn to balance.2×4 if you’re not very comfortable on a balance beam.It’s also safer, since you’re not “falling” off anything. Simply laying the pieces directly on the ground works too. You could attach support pieces underneath on either end running perpendicular to raise the beam off the ground and provide more stability, but you don’t really need to. Long pieces of lumber are relatively inexpensive balance beams that are easy to transport. Here’s some of the supplies I’d recommend getting your hands on and what you can create with them. It can be a different course every single time. You can bring them to the park or the beach and set up an obstacle course wherever you want. You can adjust the layout, bringing the jumps closer together or farther apart as you progress in skill and strength. The beauty of these types of obstacle courses is that they are endlessly modular. It’s a bit more attainable that way for the average person. I’m more interested in constructing ad hoc adult obstacle courses using simple objects you might already have lying around or can easily obtain at Home Depot. If you’re handy, you can do it yourself, but, again, it will take a lot of time. There are prefabricated adult play structures you can buy or companies you can hire if you want to go that route. Building an adult obstacle course a la Tough Mudder or Spartan Race or Ninja Warrior is a noble goal, but not everyone wants to spend their weekends building a complex network of lumber-heavy structures that fill up your backyard.
