A children's book about fitness, written by a local personal trainer, warns its readers to use the book with caution as it may cause the likes of tiredness, sore muscles, happiness and a sense of accomplishment.
For Instinctive Fitness personal trainer and author of Safari Fitness Wild New Zealand, Calvin "Mitch" Mitchell, health and fitness has been a massive part of his life.
He says it made him sharper and more decisive while in the army, and made him mentally stronger when in 2011 his oldest daughter was diagnosed with cancer.
Mitch says the children's book is predominately about fitness.
It is written in both English and Māori, and has fit tips throughout the book.
