These were one of the first things we bought a few years ago (via Amazon). We also bought a wooden set but found these plastic ones held up better outdoors. Additionally, they work well for adult exercise.
SLACKERS NINJA LINE INTRO KIT
When it became obvious we needed more than just the rings, we added this Slackers Ninja Line Intro Kit (via Amazon) to our setup. My oldest became super strong and was very pleased with the calluses she built up on her hands.
CLIMBING ROPE LADDER
To assist with getting up to the Ninja Course, we then added a rope ladder similar to this one found here on Amazon. We purchased ours from Dick’s Sporting Goods (ours wasn’t rainbow colored unfortunately), but I don’t see it listed on their website anymore.
SLACKERS NINJA WHEEL
When we were at Dick’s Sporting Goods awhile back, my husband found this Ninja Wheel to add a little challenge to our course. They still had it available online here, but I am sure you can also find something similar online at Amazon if you want to do one-stop shopping.
TRAPEZE SWING BAR
This was one of our latest additions (when it became obvious COVID life was going to be the norm for awhile) and I personally think it looks like the most fun. We got ours here on Amazon.
CLIMBING CARGO NET
Because one climbing ladder is apparently not enough, my husband bought this one from Amazon. While I originally thought is was unnecessary (no one asked me though), it actually works out well for my younger one because it is sturdier and easier for her to climb.
Our kids love to climb so these climbing holds from Amazon are the perfect setup to help them get up a big tree. Unfortunately, our backyard tree isn’t that big so my oldest wasn’t too impressed, but they are fun anyways. If you have a big tree, these would be awesome.
Lastly, because my kids have also become obsessed with the new game show Floor is Lava, my husband found these riverstones online at Fat Brain Toys to create a full backyard course complete with chairs, skateboards and whatever else we had lying around. He chose these particular riverstones because they had rubber all the way around them (rather than just at the corners) to help prevent slippage.
The great thing about these pieces are that you can pick and choose what works for your backyard setup, child’s age, ability or interest, and can be purchased slowly over time (breaking up the cost). Before we had the monkey bars installed, we just attached the rings and other pieces to our existing pergola. Both setups were great, and have been perfect for helping to work off some of that endless energy my kids have. Who knows, maybe someday I will even be able to do the monkey bars as easily as them!
