Here are a few tips to make it easier: stay hydrated, choose water over alcoholic drinks, pack your own quality snacks and eat often (to avoid expensive shops and not eat poorly), stretch, eat well, walk or bike more often, eat vitamins, take a good sleep and stay active for a long time.

Try to manage to find the time and motivation because working out during a rightly deserved vacation can be difficult. Try getting creative and swimming laps at the hotel pool or asking the concierge to help map out a scenic run. You can also bring your morning routine with you. Starting the day correctly is important, so stick to the routine you maintain back home when staying in a city for more than a day.
