If you want to get into better shape but you can't afford a gym membership there is good news! You can get a great chest workout from home.  Most people aren't even ready to use weights when they sign up for a gym.  Your body can get a great workout for months in the comfort of your own home.  Sure, if you want massive pecs you will need to lift some serious weight eventually, but the first 2 months can be done at home.

Working the chest is all about feeling the pump while you are lifting.  If you are doing pushups and you can't feel you chest getting tighter with each rep, you are doing them wrong.  This is why it is so important to start with something simple like a push up.  You don't want to go heavy fast because you might get stronger but your chest won't look as good.  So focus on going slow and squeezing your chest at the top of every movement.  You will have to make a conscious effort to do this until it becomes habit to feel every rep in your chest.  This is the only way you are going to get a full chest.  Focusing on the contraction will fill out your chest more than doing heavy weight but not feeling the burn in the chest.  This is why it is always great to start with a home chest workout before hitting the weights at the gym.
