First off.................NEVER BE ASHAMED OF HOW MUCH YOU CAN LIFT!
We all have to start of somewhere. With proper diet and training you can achieve your goals. And never let someone stop you from achieving them. Your stats aren't embarassing, they are real. You have helped yourself out much more by posting real stats. There are many people that will lie about what they can lift, which makes no sense at all. If you are bodybuilding its not how much you can lift, its how much you can control when you lift. Don't get into the losing form for weight, thats when you can get injured and also hinder possible gains. With proper diet and exercise your strength will increase. As for you question about bodybuilder routines try to buy some magazines like muscle and fitness and flex. They tend to have great sample routines and articles where you can learn a lot about stuff. Even search for training routines online. Try a few and see what works for you. Listen to your body as everyone's reacts differently. I seriously haven't trained arms in a year because they grow ridiculously fast. I don't know why but they just do (wish I had that problem with my calves lol) But once you find out what works for you just stay determined and don't skip days or meals and really focus on your goals thats when you will be able to obtain them.
