Look what we stumbled across on the folks' bookshelf!
Developed by the Royal Canadian Air Force. This edition of the book was published by Penguin in 1964 but an earlier abridged version came out in 1958.
It may be vintage but the exercises, tips and advice are still very relevant.
For example, on P19 it reads:
"'It won't do you any good to exercise unless you do it until it hurts', the saying goes. This is absolutely false. Although you may get some benefit from doing exercises until 'it hurts', this is not necessary in order to acquire an adequate level of physical fitness. As a matter of fact, greater benefits can be derived from exercise by avoiding stiffness and soreness."
