Being generous in assuming you mean while remaining in the USA: The Amish are quite prevalent in Pennsylvania, Ohio, and Indiana. They've already done the hard work. Joining them may take some small amount of personal sacrifice, perhaps — there is no such thing as a free lunch — but is quite doable for someone who wants it. Like the six pack, all you have to do is jump in and do it.

Alternatively, you can produce your own metaphorical weights and food supply that is to your exact liking, but that is obviously going to take singificantly more input for you to setup and is going to be heavily dependent on other people to buy into your exacting specifications. This route would not allow you to just jump into building the metaphorical six pack at your leisure. It could take many years before you are even able to first produce weights/food, let alone starting to apply them to your six pack journey. But the best time to plant a tree was 20 years ago, as they say. It will never happen if you don't do anything, that much is certain.
