If you need to rally your energy, and cure your body of exhaustion without sleep, get dancing. Listening to fast-tempo music you like pushes you to workout harder. So to score the combined effects of music and fitness (and taste the local vibe) find a strip of nightclubs. “Hitting a nightclub is a great way to get some exercise and have fun at the same time,” says John E. DiScala, founder of travel website JohnnyJet.com. “Plus, you really get a sense of the local flavor of your destination.” Ask your concierge for a list of local hot spots to work up a sweat.
