When training outdoors, it is inevitable that I'll do some kicking practice; using an actual target is much better practice than just air kicking.
It turns out that it is often easy to find a tree with a trunk with a size similar to a kicking bag, but not only can the hard trunk be bad for your feet, rough bark also won't be kind to your training shoes.
What are good options to overcome these issues?
I have tried putting a Taekwondo body protector around the trunk, but didn't like the result; it isn't easy to fasten it to the tree, and with each impact, the bark can make holes in the body protector.
Perhaps using a (cheaper) foam gym mat fastened to the trunk with an elastic band could work?
Or maybe this is not such a good idea (yes, a part of me tells me that it looks weird)?
