The SHIIT Workout: Get Fit While You Sh*t

The hilarious Sunday Times bestseller! Reached number 5 in the paperback non-fiction chart - sadly not number 2!

Get fit while you sh*t with this rather amusing and slightly silly parody of the HIIT workout phenomenon

This is for the multitaskers, the toilet-lovers, the bottom-tooters, the widdlers, the toilet-paper origamists - yes, I'm talking to you! You thought there would never be an exercise regime that you could enjoy in the comfort of the smallest room, but here it is: The SHIIT Workout. It even has pictures and planners to log your workouts.

Getting into shape has never been more fun, as you go through the (bowel) motions from jumping jacksies and push-outs to bottom burpees and skidders.

This is the essential guide to getting fit while you SHIIT.

Just make sure you have plenty of toilet roll handy as it's going to get messy - you're going to do more than sweat.
