Listen to your body

If jet lag or schedule changes leave you exhausted, make your workout shorter or lighter than usual. It's OK to take it easy once in a while. Because travel can be so disruptive to how you sleep and what you eat, it's not always the best time to try to increase your fitness level.

Remember, however, that regular exercise can help reduce stress and feelings of low energy, which might be just what you need to get down to business.
