Hard core fitness:
Pick up a big log and throw it. Walk up to it, pick it up, throw it again. Repeat.
Fill a backpack with sand. Climb a tree.
Carry a dog through a waist-deep mud bog.
Hard core fitness with a bike:
Pick up a bike and throw it. Walk up to it, pick it up, throw it again. Repeat.
Tie a bike to your back. Climb a tree.
Carry a bike through a waist-deep mud bog.
If those things are not hard core enough:
Bring a friend and have him punch you while you do it.
Or hit you with a broom handle.
Or some sort of giant piece of metal.
