i discovered scooby through a friend of mine a long time ago and his tips really helped getting me started with weight lifting. i have lost all my back problems since then. just remember, as long as an exercise feels good, it is unlikely to hurt you. i had to learn this the hard way, i pushed too hard on an exercise, ignored the pain and was left with a typewriters cramp, not so great if you are in front of a computer typing all day long. so start small and build your way up.
