OP, are you looking for different exercises to do when hitting each muscle group, or an alternative to going to the gym? If it is the former, what are are you currently doing at the gym each seperate day? What is your height, weight, and body fat percentage? What's your diet like?
As a gym rat I could probably help you switch up a mundane routine and make things more exciting. I could also help you with food tips to reach the goals you mentioned in another post which generally derive from good dieting
