Most machines have diagrams of how they work at Planet Fitness. You can also learn by watching others. Get a good book on exercising. I don't know if they still sell it but, Arnold Schwarzenegger's Encyclopedia of Body Building is very good.

Buy this. Dont listen to anyone else about anything.
Cut out the carbs and the fat. Get a good book on lifting.
I recommend Arnold Schwarzenegger's Encyclopedia of Modern Bodybuilding.
