dynamic tension exercise results? is it worth the time?

[matthewb]

i'm interested in the charles atlas program, and dynamic tension exercise in general. i was wondering if it's worth my time. can anyone help me choose. i have no money for equipment or the gym, so this is all i got. charles atlas occasionally used weights, so getting an idea of the effectiveness of the exercise ain't so great from his example. could anyone help me on this. btw, pic of before exercise and after a few months, or a general time-line would be great.
