Can someone tell me how much weights armor, because I want to buy it to train with it... if it has 7 or 8 pounds, I would like to run with it and do all kinds of exercises.Is there any types of them that are smaller like I saw in the movies when agents are wearing it under the clothes? :)

Just out of curiosity, why would you work out wearing body armor instead of clothing with weights in the pockets? At any rate - BulletProofME.com Body Armor / Bullet proof Vests (http://www.bulletproofme.com/)
