When you travel, there's no need to put fitness on hold. If you're traveling by plane and time permits, stroll through the airport terminal rather than sitting at the gate. When traveling by train walk through the cars occasionally. If you're driving, take breaks to get out and stretch. Choose a hotel that has fitness facilities. Or pack your jump-rope or resistance tubes to use in the hotel room. When you arrive at your destination, set the tone for your trip by working out right away.
