I read a good strength training book over the weekend by Mark Lauren called "You are your own gym":

It is an awesome approach to building elite fitness. Mark Lauren shares his years of training elite SpecOp military forces with the rest of us. I really enjoy these exercises because they can be done anywhere at anytime with just your body and some common household items like phone books and broom handles. His approach is not a very long program -about 6 weeks- and is designed to get SpecOps ready for the battle field as quickly as possible. After 9/11, there was a need to ramp up special forces in the shortest amount of time to get them into the field quickly,ready for any physical challenge. Each exercise is fully explained and has a few different variations depending on your fitness level. I plan on using these exercises as a way to ramp up fitness in order to compete in cross fit regionals next year.

There is also a DVD by Mark Lauren with the same title I am thinking of ordering. It will help form ritual-based motivation for these types of exercises. Right now I do not have it in me yet to set up my own programs based on the book alone.

These are more geared towards men, but women can do the exercises also and achieve the same type of results. There is another book called "Body by You" which is also by Mark Lauren

This one is focused on exercises for women to get into elite shape.

One of the PA's from my doctor's office recommended that. I see that there is a phone/tablet app out there as well. I may have to give it a try.
