I fail to understand; lifting heavy things is killing you??
Now I might get flamed for this but I interpreted that to mean you don't like going to the gym. Since you are just a begginer you can make many great gains from home so long as you eat like a horse. Just improvise, use a rucksack with weight plates for squats, use the tabata method, chins off a doorframe, calf raise on your stairs, hindu pushups, king deasdlifts and eat a lot. This isn't ideal though, get to a gym if you can.
