The mother of all fitness manuals, this 85-page guide based on the popular Crossfit London i-Course is your passport to all the essential functional fitness skills, from the olympic lifts to kettlebells to gymnastic rings and more. Whether you are a Crossfitter or simply a functional fitness enthusiast, this manual should keep you busy for the next few years – at least!

From the blog: “The overall thrust of the manual is not: here’s an ideal way to do this difficult move that only super-flexible 12-year-olds can pull off, but more: here are some safe progressions that you can practise on your own. Eventually you will be able to put them all together.”
