Having had to travel so extensively in the military for many years and often finding myself in places with no gym, it's interesting to think back on the things I once used to get a workout in. Often using bags of water, rocks, pull ups or climbing the ocassional tree and even other people. The sky is the limit when one has to resort to alternate means for a workout. This was a fantastic read and brought back a lot of memories some of which gave me a good laugh. Thanks..
