Pick up the current edition of Men's Fitness (UK) - June 2011 and there is a free 33 page guide. A workout manual for those new to training and for those who are experienced but want a different perspective on training.
Another reason for the plug is because I have contributed to the Training Toolkit. Here's a quick sample on how to motivate yourself with activity outside a gym environment:
"You shouldn't think that the only thing you can do outdoors is run or play sports. Use your imagination and the environment as a gym. Interact with nature as well as urban features. For example use a tree branch to do a pull-ups.
Base your circuit on what you can see around you, keep your mind focussed on the process as well as the end result."
