Staying home doesn’t mean you can’t keep climbing, surfing, or riding your bike. It just means you have to get creative—and finally finish those indoor training tools you’ve always wanted, including hangboards, balance boards and bike trainers.

Building these outdoor fitness optimizers at low cost lets you productively feed your stoke until you can gear up and head out once again.
Here are four DIY guides to inspire home-built training tools for your outdoor activity of choice. Like the outdoor sports themselves, constructing and using any of these trainers is at your own risk. Be smart and use proper safety measures when building (and recreating) indoors.
