I'll paraphrase a friend of mine from the seventies:
"I started out backpacking.
Then I started climbing mountains because it made the backpacking more challenging.
Then I started rock climbing because it made me a better mountaineer.
Then I started bouldering because it made me a better rock climber.
Then I started lifting weights because it made me better at bouldering.
Now I spend all my time in camp lifting weights."
