With only a pullup bar, I can do one of the best workouts that I have ever done.  Even with a gym full of equipment, we still often just do this super simple workout.  If I am truly relegated to the hotel gym for safety reasons (like in Africa) I can complete this workout with a pullup bar and a treadmill which most gyms have.

Often when traveling for trade shows, fishing tournaments, or filming time; space and equipment can be severely restricted.  I have collected a ton of different ways to stay in shape while traveling whether I am in a hotel, a Mothership or a secluded island in the Bahamas.  Here is another of my favorite workouts for limited time, equipment and space:

Simply run 3 miles and at any time, anywhere at your discretion, complete 300 pushups.  These can be done before, after or during.  Lots of times, I have completed 50 right at the starting line and then run for a while and periodically hit another 50.  Traffic lights or intersections are great opportunities to drop and do 50.
