Is there a kinesiology book that discusses exercise routines and attempts to break down muscle action into simple vector physics (fiber direction/fiber friction?
Supertraining by Dr. Mel Siff is probably the best book ever written on strength training/kinesiology/biomechanics...anything you need will be covered in there.
I'll second the late Dr. Siff's book Supertraining. Excellent book covering the physiology and biomechanics of strength training. Not your typical workout book though. It's a very dense text.
I would also check out stuff by Vladimir M. Zatsiorsky, first his Science and Practice of Strength Training and then you might also check out his biomechanics textbooks.
Where do you get this book? I checked online and there is no book called supertraining on amazon or barnes and nobles or any of the used bookstores.
Does anyone have a used copy they can sell to me?
To add to the list, one of my favorites is "Anatomy of Movement" and "Anatomy of Movement: Exercises" by Blandine Calais-Germain (a physical therapist)
