The gyms sport everything from pullup & parallel bars to vertical presses to elliptical machines. Clapham Common, where I exercise, possesses at least three outdoor gyms that are heavily used every day and have surprisingly low maintenance plus resistance to the elements.
"Great; loads of gyms! Now what?"
The phrase weary traveler is fairly descriptive of the effects of travel on people. Whether you are walking, sitting or sleeping for a long time, the effects are similar: you are tired! And the last thing you want to do when you’re tired is exercise. This needs to change.
Do you have a good work ethic? Are you rarely late to work or meetings? What is it about these that make you attend and do so in a timely fashion? You probably say, "This is something I have to do, so I am going to power through and do it, even if I don’t want to." So why not treat exercise in this manner?
In short, you need to learn to treat exercise like an unavoidable daily event; like a meeting. If you can do this, then all procrastination and "I’ll do it when I feel like it" excuses go right out the door.
If you are worried about not having a place to work out in the area you are traveling to, do a little research beforehand.
Ultimately, all of these decisions come down to you. Whether you are on a short trip or are doing extensive traveling, if you take it upon yourself to strive for a sound mind and body, you will find a way to better yourself while on the road.
