Sightsee

You don't need a gym to get an energizing workout. If you're vacationing in a city, rent a bike and pedal around town. If you're in a place surrounded by natural beauty, explore the terrain with a daily morning hike. (Bonus: Walking in nature can significantly boost your self-esteem and mood, according to a 2009 study.) Reluctant to leave the resort? The natural resistance of water makes the swimming pool a great place to do strength exercises like leg lifts and arm raises.
