answer to your first Q: just do loads of press ups, sit ups squats, lunges, all without weights obviously and do different variations. its good to have a week off every now and again for optimum recovery. if you have milk jugs, you can do the milk jug workout which can be found on the web.
answer to your 2nd Q: if you are still new to bodybuilding, personally il just stick to basic supplements. but its your choice. show your mom the definititon of anabolic and it is not always linked to steroids. amino acids should create a anabolic environment in your body, therefore promoting growth e.t.c. supplements are ment for that purpose, supplementing a solid diet. DO NOT become dependant upon them. nothing can replace foods
thirdly, i suggest that you read tonnes of books and online articles, preferbally on bodybuilding.com to expand your BB knowledge
