I was just gonna mention that if you want to hike and strengthen your core, wear a pack with some weight in it. Preferably sand you can dump if you can't make the hike back. you puss.

:edit I have the advantage of a treadmill. I can adjust uphill, get off when I'm tired I just ease it down to a slow walk and get off. I can also take off my backpack of ankle weight and not have to worry about lugging them any further.
