On a recent trip to Portland, Oregon I was inspired to make a video about practicing in places with limited space and came up with this video. Unfortunately I didn't have a microphone available so some of the sound levels are pretty low. You can adjust the sound or better yet just click on the "Closed Captioning" [CC] icon and you can read without adjusting your volume.
Practicing in a smaller environment is not difficult. It is a matter of adapting your movements to the area you have. I hope you find this video helpful.
