How can I possibly start working out?

I want to start working out, and one of my friends who already does so suggested we could go to the gym together, but I can't. My parents say I don't have time for it, and they won't pay for it. With my job I don't earn enough to pay myself. I have considered working out at home, but I don't have the necessary space and equipment to work out. I can't think of any solutions for this problem. All suggestions are welcome!
