A few years ago I got a lend of the Warrior Guide to Underground Fitness by a guy called Ross Enamait (recommend you have a look). Well, he popped back into memory there and it prompted me to google him and I found his website, http://www.rosstraining.com. His site has completely changed since I last visited years ago. It’s a brilliant resource, the forum has literally tens of thousands of posts on all kinds of underground fitness. I recommend you go over and check it out. He also has a load of handy guides for making your own fitness gear for home. Can’t beat it!
