Here's a few that I would suggest..."Combat Conditioning" by Matt Furey, "You are Your Own Gym" by Mark Lauren and Joshua Clark, and "The Naked Warrior" by Pavel. All have a mixture of strength and flexibility exercises. As another post mentioned, CC is another good source. One source from a different perspective that I would offer is "Yoga for Regular Guys" by D.D. Page. For just women there is "Gym Free and Gorgeous" Angelina Thiri, or "Body by You" also by Mark Lauren and Joshua Clark
That being said...I offer you will still might want some basic equipment, such as a pull-up bar. However, in many cases for ~$100 you get get a good deal on a Power Tower if you look around, and it will have a pull up bar, Roman Chair, and dip grips for BW exercises, plus sometimes have extra stuff such as grips for neutral push ups.
