Hiking takes a lot out of you, this is the full equipment I take with me for a couple of days Bushcrafting - hike, keep in mind that I carry a lot for my wife as well.
Hiking is way better than just mindless walking on a treadmill, and it's challenging work let me tell you guys.
You burn up to 5k of Calories per days hike depending how much you carry and regarding the terrain.
I have just completed my kit with two essential kits items:
1) Hand made Bushcraft knife, I tested it already on a 3 day full hike and it is amazing, lays very well in the hand and so sharp you can shave yourself.
2) Snugpak Elite, very good and very light
