Query: GREAT BOOK! GREAT WORKOUT!

I am sorry to see this book is currently out of print. Get Tough! is the toughest workout you will ever love. The exercises in this book are simple but strenuous. I liked the fact that the charts are easy to read and easy to photocopy so I can hang them on the wall. My favorite part of the book is the running schedule. (And I absolutely hate running.) It starts out easy and gradually gets harder. By the end of 12 weeks, you should be in the best shape of your life
