Little Britches - book by Ralph Moore. Some notes about the author .
Lessons from Milo of Croton
A small body will not be as heavy as a well-nourished Big'un. It is also not as thick, so it should not sink in as much as the Big'un for proper back support and weight distribution. A firm mattress will not kill you...
European beds tend to have flexible slats that supposedly adapt to your countour. This rarely works, especially when there is more than one person in the bed. I do much better with the mattress on a firm support. In other regions it is common to sleep on a futon laid on the floor.

The Physics of Resistance Exercise - book by Doug Brignole. I don't agree with all of his conclusions, but it certainly gets you thinking. Real biomechanics are a bit more complicated as we are not 2D stick figures.

Shut your Mouth and save your Life by George Catlin.
This book was originally published in 1861, so you will have to put up with some antiquated views and language. It is still worth a read, given the glimpses it gives at ancestral living. The author was a lawyer turned painter. He was fascinated by American Indians, and visited a large number of tribes. He observed their good facial and dental development, and their low mortality rate compared to "civilized" countries of the time. He pointed out that they were resolute nose breathers. Mothers closed the mouth of their babies after nursing.
Jaws: The Story of a Hidden Epidemic by Sandra Kahn and Paul R. Ehrlich
This book is about oral posture and the development of the jaw. Again, mouth breathing is the root of all evil... Interestingly, your overall posture (e.g. head position) can have knock-on effects on your oral posture and thus jaw development. Chewing tough food has a big influence on how the jaw develops. More on good oral posture exercises. In brief: Breathe through your nose. Your tongue should rest against the top of your mouth (the palate). Your teeth should be lightly together.
