Ok i have 1 hour during the day of free time that i can work out. I dont even have time to go to the gym. Im wondering can i accomplish anything doing just situps and pushups? Can i get toned or bigger or will this accomplish nothign for me? Im very skinny and my metabolism is through the roof. I smoke a pack of cigarettes a day and weed every day. Im lazy and drink a lot of beer. This isnt a joke. Im trying to get off on the right foot. I eventually would like to be in shape, quit smoking and cut down on drinking.
