First off I am not in peak condition. However, I am in reasonbly good confdition for my age, and do excersize pretty regularly except for last week when I stuffed my face on all the Hoiday left overs! [:D]. Some how eatings mass quantities of very rich food makes one lethargic...
If you bowhunt, staying physically fit is essential. The bow, no matter if it is compound, or traditional is a martial weapon. In reality is an extension of ones body. You owe it to the game you pursue to stay fit and practiced to give yourself the best possible chance of making a clean and ethical kill.
Other methods of hunting really depends on your terrain. The more rugged the better in shape you should be. I doubt I could hop on a plane, land in Alaska, and chase game for several days regardless of what type of weapon you give me, and make it back without wheezing and puffing. I would need to build up to that type of activity prior to going.
Veni, Vidi, Sagittam Mittere, now I'm ready for my nap
