"Get some weights. Pick up the weights. Put down the weights. Eat healthy food."
There is no real secret. No need for a gym to do those.
But now more seriously - I'd suggest just getting a pull up bar.
You can then do pull-ups in addition to push-ups, squats and some core work, and that'll hit all of the main muscle groups. You can do that at home.
A finger board is also great if you are interested in rockclimbing. I’ve got one installed just above my kitchen door and I have to pay the “Troll Toll” to enter the kitchen ;)
