Anyone else like to do this stuff? Strapping a pack on your back and hiking up a mountain is good stuff, steep trails make for good cardio.
Try carrying a rifle if you feel frisky. You would be surprised how hard it is just to carry an extra 20lbs on your back for 5 or 6 hours.
I love this kind of stuff, hiking trails, being in the woods, I only carry the rifle in case I see some coyotes, I have declared war on coyotes here.
