Ross Enamait has a really nice article up on his site about training in a new environment:
Improve Productivity By Changing Scenery
It's a good article. It brings me back to two of my "early days" training experiences.
First one - I used to lift in a friend's weight room in his yard. He'd converted a patio and shed into an enclosed dojo/garage gym. I used to train there in the winter, and I didn't bother to put on the heat. Partly this was not wanting to deal with lighting and running a kerosene heater. But also because it drove me to work hard and work fast. I'd go in, lift cold barbells and freezing dumbbells while sitting on or laying down on cold benches. I'd get my work done, then walk home or bike home in the cold.
Second one - I lived in Japan for a few years. I did a lot of outdoor training. I biked to parks and did pullups and muscle-ups on playground bars. I did pushups in the dirt outside. I dragged a home-made sled loaded with random heavy things (and neighborhood kids who wanted a ride) while I ran with the sled behind me. I train in and out of bad weather, bike in the snow, and otherwise go new places and train in new ways. It was limited by what I could access in the way of gear, but it didn't matter. It was all good, positive, effective training.
So read Ross's article, and go try training in a totally new place. Ignore any discomfort and make some training happen. It can make you better.
