Two must haves for any martial artist's library: "The Science of Martial Arts Training" by Charles Staley, and "Renegade Training for Football" by Coach John Davies. Both books are loaded with information about training for functional strength.
My personal favorite lifts are: deads, squats(front, back and box), cleans, push presses, snatches to name a few.
I also incorporate some more unconventional lifts (renegade style of dinosaur training to some) :lifting sand bags, tire flips(320lb truck tire),sled pulls, sledge hammer swings, farmers walks and others.
