Dude that's awesome you have lost so much! Get under the bar and start squatting and dead lifting. If you want to really build muscle drink a gallon of milk a day. You will gain some fat with this method true, sounds like you know how to take that back off fairly easily, but the mass gains from that are ridiculous! People will literally link your on steroids. As Rip says, "you are a baby lamb until your not so eat like one"
