Below is a link to an article by Ross Enemait on the benefits of training outdoors with whatever you happen to have around you-
“One of the obvious themes throughout this site is our ability to exercise with minimal equipment. As I have stated many times before, much of my training is performed with homemade tools or objects that were not initially intended for exercise. I am a firm believer in the simple premise that if you want to exercise, you have everything that you need to get started. It does not matter where you are or what you own, there is always something that can be done.
Training with minimal equipment is a way of life for me. There are few things I’d rather do than exercise outdoors and enjoy the fresh air around me.”
