There's a big difference between being in shape, and being a body builder.
To look like Arnold or Ronnie Coleman you need a gym (and steroids) To stay in shape, you can take a much simpler approach. Just use your own body weight, and when that gets easy do more of it or wear some weights while you do it.
You'd be surprised how much 10Lbs on each arm and leg effects you in a run![]()
That's pretty much what I said.
I have a backpack with a 10 to 15lbs weight when I'm doing push-ups and pull-ups.
