I'd read a fair amount of the SuperSlow articles that were freely available on the internet - there are several here - so I knew roughly what I was getting into. Renaissance Exercise's marketing strategy was to drip feed blog posts, generating interest and then to launch their machines at a major event following up with the book itself. Well it worked for me, and I ordered the book. The price put me off initially but I viewed it as a text book / investment and went for it. I emailed Drew Baye as well and he highly recommended it and he always comes across as a harsh critic.
320 pages, hardback, ribbon bookmarks, dense with information. This will be an interesting read. You can find more on the book here
